PW450D Differential Pressure Switch with display is a full digital measurement and control product integrating pressure / differential pressure measurement, display, contact control and transmission output. They mainly use silicon piezoresistive pressure sensor as the pressure sensitive core, and can also be equipped with pressure sensors such as ceramic capacitors, sapphire, sputtered film, etc., through programmable digital circuit correction and signal conditioning, output standard industrial signals, switches and quantity signal. Depending on the mode of use, the product can output 1 to 4 sets of switching signals for up to 4 pressure points. Customers can freely set switch points according to their needs. It can set zero point value, full degree value, contact pressure / differential pressure value and other parameters on site with the key.
Widely used in chemical, mechanical, hydrological, electric power systems, gas pressure control and automatic control, external intermediate relays can complete a variety of control functions.
