Bimetal thermometer wssp-411 with thermal resistance

Description

overviews

WSS series bimetallic thermometers with thermocouple (resistance) and temperature transmitter are temperature sensors for local display and remote transmission of electrical signals. The platinum resistance element is installed in the temperature measuring rod of bimetal thermometer, which can not only indicate the temperature on site, but also transmit the signals of thermocouple (resistance) and two-wire temperature transmitter. As a new generation of thermometer, wssp-411 bimetal thermometer with thermal resistance can be widely used in metallurgical, petrochemical, electric power, light textile, food and other industrial sectors.

Product characteristics

1Thermocouple (resistance), bimetallic thermometer or temperature transmitter

2The utility model has the advantages of small temperature measuring probe, high sensitivity, linear calibration, long life and so on.

3Suitable for working in harsh environment for a long time.

4The remote electrical signal has high accuracy and stable operation. It can also be output directly in the form of two-wire system to improve the anti-interference ability of the signal in the process of long distance transmission.

5, high ratio of performance to pric
