HR320 series intelligence pressure transmitter uses top quality pressure components with mixed signal processing technology and unique compensation methods to realize F S digital linearity correction, full temperature digital temperature compensation to improve the precision of the transmitter. Circuit part with power and watchdog monitor improve the reliability of the whole transmitter.
Rich product series, they are widely used in pressure measurement of oil and gas industry, hydrology and water conservancy, geological prospecting, shipping industry etc.
Digital correction
High stable pressure sensing element
With strong over load, anti-corrosion
Anti-surge, electromagnetic interference
Reverse power protection, over voltage protection
Factory calibration, no need of potentiometer adjustment, with high reliability
