Thermowell │ Thermowell Supplier Malaysia

What is Thermowell?
Thermowell is small tubular fitting which is used in temperature measurement to protect the temperature sensor from damage that could occur during an industrial process. Thermowell is otherwise commonly known as solid drilled pockets as they consist of a metal bar stock that is drilled to create an open end where the sense is inserted. If the sensor was to break during application, the user could easily replace the existing sensor with a new one.

Common uses of thermowell is very similar to that of other components. Thermowell can be used in both an existing temperature sensor setup or can be added to a new design specification. Thermowell used in many high temperature applications because they can work effectively up to temperatures surrounding 1200 °C.


What Is The Advantage of Using Thermowells?
There are many reasons why you may choose to include a thermowell in your design specification. The main reason that people often choose to use them is because they are very durable, and provide excellent protection for the sensor from external damage caused by corrosive liquids or intense temperature.

We can provide a range of additional features to your new thermowell include addition of process thread or a custom made flange which we are able to weld and test to your specification

Expert Thermocouple Manufacturer Malaysia

We, dpstar Group have been designing and manufacturing thermocouples and heaters for clients all over the world for 30 Years.

What is a Thermocouple?
A thermocouple (TC) is a sensor that is used to measure temperature. It consists of two wire conductors made out of different metals. When these metals are welded together, a junction is formed. The temperature can be calculated by working out the voltage generated when a temperature change is detected. There are a number of different TC types and designs that each performs best at certain temperatures and in specific environments.

Type of Thermocouple

Rare Metal Thermocouple
Rare Metal Thermocouple, also called noble metal thermocouples or Platinum/rhodium alloy thermocouples, and can provide bespoke/custom designed sensors to your process or work to your specification and drawings. All types of rare metal TC can be supplied including Type R, Type S or Type B.

Base Metal Thermocouple 
Base Metal Thermocouple are commonly made from various nickel alloys. Different combinations of nickel alloys have become popular industry standards. We can manufacture bespoke/custom designed sensors to your process or work to your specification and drawings in all common thermocouple types including: Type K, Type J, Type N, Type E and Type T.

Mineral Insulated Thermocouples
MI thermocouples are a stable, durable temperature measurement solution. MI TC’s consist of an outer metal sheath, which has an inner filling of magnesium oxide powder. This powder surrounds the conductors providing great thermal conduction and also enabling the sensor to be bent into various shapes without affecting the measuring point.We are able to offer mineral insulated sensors in both simplex and duplex assemblies.

Cable Thermocouples
In cable thermocouples the sensor conductors are protected by flexible cable insulation. Depending on requirements the insulation can be PVC, Silicon rubber, PTFE or Glass fibre. There are many different designs of cable TC that are suitable for almost any application.

Thermocouple Inserts and Elements
Inserts can be inexpensive to produce and are ideal for insertion into an existing thermowell assembly. We can also supply various thermocouple elements for use in your own designs or to replace your existing broken elements.

Hand Held Thermocouple Probes
We can supply an extensive range of hand held thermocouple probes for use in a variety of environments. Most hand held probes come with a mini plug for connection to hand held instrumentation.

Today, we are considered the best choice for custom built temperature sensors in the Malaysia. We continue to apply our expertise and invest in the latest technology to provide our customers with the highest quality temperature sensors available.

Introduction of Aplisens Hydrostatic level probes


Hydrostatic level probes SGE-25S and SGE-25C for measurement of waste liquid levels

Aplisens Hydrostatic level probes SGE-25S and SGE-25C are applicable to measure levels of liquids containing contaminants or suspensions. A typical use for this probe is the measurement of levels of liquid waste in intermediate pumping stations, fermentation chambers, settling tanks etc.

Principles of operation, design for  Aplisens Hydrostatic level probes SGE-25S and SGE-25C

The probe measures liquid levels, basing on a simple relationship between the height of the liquid column and the resulting hydrostatic pressure. The pressure measurement is carried out on the level of the separating diaphragm of the immersed probe and is related to atmospheric pressure through a capillary in the cable. The use of a special separator with a large uncovered diaphragm minimizes the metrological effect of sediment deposit on the diaphragm surface. This enables the probe long lifetime and proper work in contaminated media (even in the presence of abrasives, such as sand) and facilitates cleaning with delicate stream of running water (washing with water under pressure may damage the probe).The active sensing element is a piezoresistant silicon sensor separated from the medium by an isolating diaphragm. The electronic amplifier, which works in combination with the sensor, and is meant to standardize the signal, is additionally equipped with an overvoltage protection circuit, which protects the probe from damage caused by induced interference from atmospheric discharges or from associated heavy current engineering appliances

Installation, method of use for Aplisens Hydrostatic level probes SGE-25S and SGE-25C

When lowered to the reference level, the probe may either hang freely on the cable or lie on the bottom of the tank. The cable with the capillary can be extended using a standard signal cable. For the cable connection a special Aplisens SG cable hanger is recommended. The cable connection should be situated in a non-hermetically sealed box (the internal pressure inside the box should be equal to the atmospheric pressure), preventing water or other contaminants from getting into the capillary. The Aplisens PP junction box is recommended For systems with long signal transmission lines, it is recommended the using of an additional Aplisens UZ-2 overvoltage protection circuit in the form of a wall-mounted box which allows the cables connection. When the probe cable is being wound up, the minimum winding diameter should be 30cm and the cable should be protected from mechanical damage. If there is a possibility of turbulence in the tank (for example, because of the mixer operating mixers or a turbulent inflow), the probe should be installed inside a screening tube (e.g. made of PVC). The line hooked on the lifting handle can simplify the operation of the probe pulling out. Cleaning the probe diaphragm by mechanical means is strictly prohibited.

Heating Element

Heating elements can be found as a core fundamental material within electric heaters and are typically consisted of an insulating core, a heat conductive coil wrapped around the insulation and a protected sheath made from stainless steel, aluminum, nickel or iron. Heating elements can have a short lifespan if the application is incorrect, hence the need and importance that a person/company using such heaters are consulted professionally so that the right material is used. Through dpstar’s Maltec – H (Malaysia) manufactured heating elements, our experience of nearly 30 years in the field allows us to give expert advice on the right heater for every application. Replacement of such heaters within a short time period can be very expensive and be a waste of a company’s expenditure. Most industrial companies that use such heaters acknowledge our heaters because they no longer need to replace heating elements part of regular equipment maintenance so frequently. Hence maintenance department can keep less of these parts and lower their inventory. When heating elements are used wrongly in consumer items such as hair dryers or toasters, it is typically easier and less expensive buy a whole new unit than replace a single element. dpstar’s manufacturing division goes through strict quality control processes and we manufacturers industrial heaters of high quality and customers are able to save on spare part maintenance. Using the right heating element material for every application is very critical and important, as the safety and effective operation of a heating element depends on it. Using wrong heating elements can potentially cause danger and risks such as fires, burning, product damage, equipment breakdown and many other problems.

dpstar’s Maltec H heating elements is able to offer our wealth of experience for heater applications so that such extra costs and problems do not occur to our customers.


Heating Elements

Most equipment or machinery that require heat to perform their processes use a heating element of one kind or another. Furnaces, heating process lines, oven dryers, water heaters, and other machine makers approach dpstar’s Maltec H range of manufactured heating elements for their heating requirements. The amount and wideness of the our customer base who purchase such heaters for their process application is almost uncountable. For example one of our biggest markets is in the packaging industry where these players use applications such as plastic fabricating, foam fabricating, metal fabricating and food processing industries, cartridge heaters are inserted into the machine where the heating is required. Immersion heaters and tubular heaters are used when the application required the heat to be transferred into liquid or air in industrial drying ovens, storage tanks for temperature control, pressure vessel heating, steam generation, furnace and boilers, water treatment facilities and many other applications.For instance, immersion heater elements are required when a process such as food manufacturing or drinks production takes place.

dpstar makes such heating elements and through our wealth of experience, we have been a renowned supplier and manufacturer of these heaters in the Malaysia market.
