Designed for industrial environments, it supports three-wire PT100 temperature measurement, provides 4-20mA standard signal output and dual relay alarm

The TT-SXWT-A temperature transmitter launched by Weite Technology Co., Ltd. is a set of​​High-precision temperature measurement​​、​​Standard current signal output​​and​​Dual relay alarm​​An intelligent industrial instrument with integrated functions. This product adopts advanced sensing technology and intelligent processing algorithms to accurately monitor the ambient temperature and convert the measurement results into a 4-20mA standard signal output. At the same time, it provides two sets of programmable temperature alarm thresholds to meet the temperature monitoring needs in various industrial scenarios.

Product core functions

Accurate temperature measurement

Our temperature transmitter supports three-wire PT100 platinum thermal resistance, and the measurement range covers​​-20℃～160℃​​, The resolution reaches​​0.1℃​​, To ensure that you get accurate and reliable temperature data. Stable performance can be maintained even in high-interference industrial environments.

Standard signal output

The equipment provides 4-20mA analog signal output, which can be easily connected to various acquisition equipment, PLC systems or DCS systems. Users can freely set the temperature values corresponding to 4mA and 20mA through the panel or MODBUS communication, which can be flexibly adapted to different application scenarios.

Dual alarm function

TT-SXWT-A type temperature transmitter is equipped with​​Two sets of independent programmable alarm relays​​, Each relay can set a separate alarm threshold and an alarm threshold. When the temperature exceeds the set value, the corresponding relay contacts are closed, which can directly control the field equipment or trigger the alarm system.
