Hydrostatic & Submersible level transmitters

Hydrostatic level transmitters use the static head pressure generated by a volume of fluid due to gravity. Hydrostatic level transmitters work in the same way as conventional pressure transmitter do, however they are located at the base of the intended measurement range and will output a signal proportional to the change of level in the fluid above. Our range of instruments are all provided with atmospheric references to ensure external pressure fluctuations don’t effect your measurement.

Aplisens’s range of Hydrostatic Level transmitters use advanced measuring cells that enable measurement of level as low as a few centimeters up to 500 meters of H2O. This makes them ideal for all sorts of applications ranging from small batch tanks to deep bores and wells. Our range of hydrostatic and submersible level transmitter also includes HART, Profibus and Modbus protocols complementing IECEx, ship building, PED and MID certification and approvals. Various materials such as 316SS, Hastelloy and Titanium are also available to suit corrosive fluids and environments.

Thermocouple – Leading Supplier of Thermocouples

Types of Thermocouples:-

Before discussing the various types of thermocouples, it should be noted that a thermocouple is often enclosed in a protective sheath to isolate it from the local atmosphere. This protective sheath drastically reduces the effects of corrosion.

1. Type K Thermocouple (Nickel-Chromium / Nickel-Alumel)
The type K is the most common type of thermocouple. It’s inexpensive, accurate, reliable, and has a wide temperature range.

Temperature Range:
Thermocouple grade wire, –454 to 2.300F (–270 to 1260C)
Extension wire, 32 to 392F (0 to 200C)

Accuracy (whichever is greater):
Standard: +/- 2.2C or +/- 0.75%
Special Limits of Error: +/- 1.1C or 0.4%

2. Type J Thermocouple (Iron/Constantan)
The type J is also very common. It has a smaller temperature range and a shorter lifespan at higher temperatures than the Type K. It is equivalent to the Type K in terms of expense and reliability.
Temperature Range:
Thermocouple grade wire, -346 to 1.400F (-210 to 760C)
Extension wire, 32 to 392F (0 to 200C)

Accuracy (whichever is greater):
Standard: +/- 2.2C or +/- 0.75%
Special Limits of Error: +/- 1.1C or 0.4%

3. Type T Thermocouple (Copper/Constantan)
The Type T is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers.
Temperature Range:
Thermocouple grade wire, -454 to 700F (-270 to 370C)
Extension wire, 32 to 392F (0 to 200C)
Accuracy (whichever is greater):
Standard: +/- 1.0C or +/-0.75%
Special Limits of Error: +/- 0.5C or 0.4%

4. Type E Thermocouple (Nickel-Chromium/Constantan)
The Type E has a stronger signal & higher accuracy than the Type K or Type J at moderate temperature ranges of 1,000F and lower.
Temperature Range:
Thermocouple grade wire, -454 to 1600F (-270 to 870C)
Extension wire, 32 to 392F (0 to 200C)
Accuracy (whichever is greater):
Standard: +/- 1.7C or +/- 0.5%
Special Limits of Error: +/- 1.0C or 0.4%

5. Type N Thermocouple (Nicrosil / Nisil)
The Type N shares the same accuracy and temperature limits as the Type K. The type N is slightly more expensive.
Temperature Range:
Thermocouple grade wire, -454 to 2300F (-270 to 392C)
Extension wire, 32 to 392F (0 to 200C)
Accuracy (whichever is greater):
Standard: +/- 2.2C or +/- 0.75%
Special Limits of Error: +/- 1.1C or 0.4%

6. Type S Thermocouple (Platinum Rhodium – 10% / Platinum)
The Type S is used in very high temperature applications. It is commonly found in the BioTech and Pharmaceutical industries. It is sometimes used in lower temperature applications because of its high accuracy and stability.
Temperature Range:
Thermocouple grade wire, -58 to 2700F (-50 to 1480C)
Extension wire, 32 to 392F (0 to 200C)

Accuracy (whichever is greater):

Special Limits of Error: +/- 0.6C or 0.1%

7. Type R Thermocouple (Platinum Rhodium – 13% / Platinum)
The Type R is used in very high temperature applications. It has a higher percentage of Rhodium than the Type S, which makes it more expensive. The Type R is very similar to the Type S in terms of performance. It is sometimes used in lower temperature applications because of its high accuracy and stability.

Temperature Range:
Thermocouple grade wire, -58 to 2700F (-50 to 1480C)
Extension wire, 32 to 392F (0 to 200C)

Accuracy (whichever is greater):
Standard: +/- 1.5C or +/- 0.25%
Special Limits of Error: +/- 0.6C or 0.1%

8. Type B Thermocouple (Platinum Rhodium – 30% / Platinum Rhodium – 6%)
The Type B thermocouple is used in extremely high temperature applications. It has the highest temperature limit of all of the thermocouples listed above. It maintains a high level of accuracy and stability at very high temperatures.

Temperature Range:
Thermocouple grade wire, 32 to 3100F (0 to 1700C)
Extension wire, 32 to 212F (0 to 100C)

Accuracy (whichever is greater):
Standard: +/- 0.5%
Special Limits of Error: +/- 0.25%

Introduction of Thermocouple

What is a Thermocouple?

A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then be interpreted using thermocouple reference tables to calculate the temperature.

There are many types of thermocouples, each with its own unique characteristics in terms of temperature range, durability, vibration resistance, chemical resistance, and application compatibility. Type J, K, T, & E are “Base Metal” thermocouples, the most common types of thermocouples. Type R, S, and B thermocouples are “Noble Metal” thermocouples, which are used in high temperature applications.

Thermocouples are used in many industrial, scientific, and OEM applications. They can be found in nearly all industrial markets: Power Generation, Oil and Gas, Pharmaceutical, Bio Tech, Cement, Paper & Pulp, etc. Thermocouples are also used in everyday appliances like stoves, furnaces, and toasters.

Thermocouples are typically selected because of their high temperature limits, low cost, wide temperature ranges, and durable nature.

Advantages of MI Cable

The metal sheath that clads MI cable helps to protect the thermocouple wires from oxidation when used in chemically active or wet environments. Corrosion resistance makes MI cable ideal for use in areas where failure and replacement could be dangerous or even impossible. For example, MI cable is used in nuclear plants to monitor core temperatures. It would be extremely dangerous if the temperature controllers were not receiving accurate readings, and it would be difficult to repair or replace cables in that environment.

The mineral fillings in MI cables provide excellent non-reactive insulation, preventing the thermocouple wires from contact with each other or with caustic substances such as oils, solvents or water. This helps to ensure that the thermocouple probes remain accurate, critical in applications such as heat treating or sintering where the quality of the product could be adversely affected by temperature fluctuations.

The insulation in MI cables does not burn, which makes it ideal for applications where fire could be catastrophic. Medical devices, power plants and oil rigs are examples of places where installation of MI cables makes operations safer.

Since the thermocouple probes are protected from contact with other electrically active wires by the insulation, they are not readily subject to malfunction or inaccurate temperature measurements. Carefully calibrated to meet international standards, MI cables provide accurate and precise temperature measurement over long duty cycles with little or no loss of accuracy.

Because of the mineral insulation, MI cables can operate in high temperature conditions with no loss of accuracy. This makes them ideal in kilns, firing ceramics or heat treating metals or in any high temperature process. MI cables retain their accuracy even during and after exposure to high temperatures, so they are ideal as a thermocouple probe in these operations. In addition, for industries such as medical devices or aerospace where safety standards are strictly enforced, process deviations could result in life threatening quality issues
