Product Overview

The temperature transmitter product uses PT100 (1/3B level) as the signal measurement element, and has undergone computer automatic testing. It has been compensated for zero and sensitivity temperature over a wide temperature range using laser resistance adjustment technology. The amplification circuit is located inside a stainless steel casing, converting the sensor signal into a standard output signal, fully leveraging the technological advantages of the sensor and providing excellent performance to the temperature transmitter. It has anti-interference, overload, small temperature drift, high stability, and high measurement accuracy, making it an ideal temperature measurement instrument in the field of industrial automation

working principle

A temperature transmitter is a PT100 sensor that produces a resistance effect under the influence of temperature. It is converted by a dedicated processing unit to generate a differential voltage signal, which is amplified by a dedicated amplifier to convert the signal corresponding to the range into a standard analog or digital signal.
