Precision manufacturing for demanding applications, Resisten temperature sensors are meticulously made to ensure reliability, quick response and accurate sensing. People involved in critical process control of food, plastics and metal rely on our sensors. There are three ways to detect temperature: RTD, Thermocouple and NTC.

Contain a sensing element which is an electrical resistor that changes resistance with temperature. This change in resistance is well understood and is repeatable. The sensing element in an RTD usually contains either a coil of wire, or a grid of conductive film which has a conductor pattern cut into it. Extension wires are attached to the sensing element so it’s electrical resistance can be measured from some distance away. The sensing element is then packaged so it can be placed into a position in the process where it will reach the same temperature that exists in the process

Contain two electrical conductors made of different materials which are connected at one end. The end of the conductors which will be exposed to the process temperature is called the measurement junction (hot end). The point at which the thermocouple conductors end, usually where the conductors connect to the measurement device, is called the reference junction (cold end)

NTC Thermistors:
NTC are thermally sensitive resistors whose prime function is to exhibit a large, predictable and precise change in electrical resistance when subjected to a corresponding change in body temperature. Negative Temperature Coefficient (NTC) thermistors exhibit a decrease in electrical resistance when subjected to an increase in body temperature. They are capable of operating over the temperature range of -50°C to +150°C. Because of their very predictable characteristics and their excellent long term stability, thermistors are generally accepted to be the most advantageous sensor for many applications including temperature measurement and control.
