dpstar thermocouple sensors are temperature sensing devices that consist of two different metal alloys which will produce a voltage directly proportional to the temperature difference between the conductors. They are self-powered sensors requiring no external form of extraction. dpstar thermocouples sensors are less expensive, have greater temperature ranges then a traditional RTD, provide accelerated response times (less than one second) and are extremely robust. dpstar is the best Malaysia manufacturer and supplier.
