China Jfa701 Piezoresistive Silicon 4-20mA Small Miniature Pressure Sensor Transmitter

JFA701 Piezoresistive Silicon 4-20mA small miniature pressure transmitter
Description:
JFA701 miniature 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.
