HW-180 series pressure transmitter

The HW-180 series pressure transmitter has advantages such as reliable operation, stable performance, easy installation and use, small size, light weight, and high cost-effectiveness. It can be widely used in various positive and negative pressure measurements. Imported diffused silicon or ceramic core is used as the pressure detection element, and the sensor signal is converted into a unified output signal of 0-10mA or 4-20mA through a high-performance electronic amplifier. It can replace traditional remote pressure gauges, Hall elements, differential transmitters, and has the performance of DDZ-II and DDZ-III transmitters. It can be used in conjunction with various types of dynamic coil indicators, digital pressure gauges, electronic potentiometers, as well as with various automatic adjustment systems or computer systems.
