JFA701 small oil pressure sensor

widely used in the field of petroleum, chemical, metallurgy, electric power, hydrology and other industrial pressure measurement and control

Category: pressure sensor/transmitter

产品描述标题.jpg

The pressure transmitter adopts a piezoelectric sensor with a stainless steel isolation diaphragm as 

a signal measuring element, and though the computer-auto-test. Temperature compensation of the 

zero point and the sensitivity of the temperature range is carried out by using a laser trimming process. 

Amplifier circuit is located in the stainless steel housing. The sensor signal will be converted to standard 

output signal. After the entire product components, semi-finished products and finished products rigorous testing.

Due to it have high reliability, wide adaptability, flexibility and variety. The product is commonly used 

in the field of petroleum chemical, metallurgy, electric, hydrology and other industrial processes' s pressure 

measurement and control.
