PW221D electronic Pressure Differential Switch adopts ceramic or film technology to ensure the high precision and durability of the sensor. With on-site display, LED digital display of on-site pressure or setting menu. Switch status, menu setting switch point, analog quantity starting and ending point, output function, storage function and display function, so the setting need not be completed on the spot. With high reliability, output can be directly used for PLC. M12 locking connector, easy to disassemble and connect, high level of protection. Positive or negative pressure can be measured. The sensor can be used as both a pressure switch and a pressure transmitter because it has both a switching output and an analog output. The display shell can rotate freely in the range of 270°, fully meeting the visual requirements.
PW221D electronic pressure switch Gas-liquid dual-use, suitable for: pump control, tank detection, liquid level control, filter plugging, monitoring, leakage monitoring, but also widely used in hydraulic and pneumatic occasions: such as mechanical equipment and process control.
Pressure switches are used in a variety of industrial pressure monitoring processes. If a preset pressure is reached, a pressure switch opens or closes a respective switch contact.
According to the functions, they can be divided into mechanical pressure switches or electronic pressure switches.
According to application, there have differential pressure switches, explosion-proof pressure switches, air compressor pressure switch, well pump pressure switch, oil pressure switch etc.
