HPM131 Air Pressure Transmitter is specially designed for measuring small air pressure. It is very convenient for measuring liquid level by air-gathering non-contact method. This product adopts imported pressure transmitter as signal measuring component and is processed though temperature compensation. The signal modulation circuit within stainless steel shell can transform the signal of transmitter to standard current signal output. It is delicate and easy to install, which can be used in narrow confines and hostile environment for a long time. This product can be widely used in industrial process control, the liquid level measurement for open vessels and other occasions.
