The pressure thermometer and the serialized temperature measuring instrument developed thereby overcome the shortcomings of single instrument performance, poor reliability and large temperature accumulation, and reduce the volume of the temperature measuring component to 1/30 or 1/60 of the original. The sensor thermal resistance is installed in the temperature measuring element to realize the mechatronics temperature measuring function. A multi-function series temperature meter with long-distance transmission, anti-vibration, anti-corrosion, electric contact and temperature signal transmission with liquid pressure thermometer as the basic temperature measuring instrument is formed.

Divided into two series,

1. Normal type

2. Explosion-proof type.
