HPT-2 digital pressure transmitter uses piezoresistive OEM pressure sensor as sensing element, which amplifiercircuit transforms sensor signal into standard output signal. Through long-term aging and stability testing, the wholeProduct’s performance is stable and reliable. The transmitter with 2-wire 4~20mADC output and local display indicacator could be widely used on pressure measure in rugged environment, petroleum, chemi-industry,etc
