Application
Diffused silicon pressure transmitters are widely used in petroleum, chemical, steel, electric power, light industry, environmental protection and other industrial fields. It has the characteristics of convenient installation, stable performance, reliable operation, etc. It is widely used in the environment of positive and negative pressure measurement. The temperature sensing element adopts imported diffused silicon or ceramic core component, and the sensor is composed of electronic amplifier, which will measure the signal. Converted to 0-10mA or 4-20mA output signal, diffused silicon pressure transmitter can be used with digital display pressure gauge, or can be used with automatic adjustment system or computer system.
