  • Temperature Transmitter PCT202B

Temperature Transmitter PCT202B


High strength, high pressure resistance

Integrated structure

Long-term stability

Fast response

Good reliability

The PCT202B integrated temperature transmitter uses the resistance of platinum resistance to change with temperature and shows a certain functional relationship to measure the temperature of the measured medium. The product consists of a temperature sensor and a conversion circuit. It has the advantages of stable performance, high sensitivity, and strong reliability.

The PCT202B integrated temperature transmitter adopts a fully welded movable thread structure and is easy to install. It is widely used in automatic temperature measurement and control systems such as petroleum machinery, chemical machinery, pumps and compressors, electric power, boilers, and natural gas.
