PNP NPN 4-20ma Digital Water Air Electronic Vacuum Pressure Switches
Description
WNK-SPS OLED display pressure control switch Can provide a continuous pressure monitoring and set the pressure switching point without supercharging. User can easily set the switching point and back-to-switching point without supercharging equipment. And can define the switch type(normal open/close), damping time,the relay and NPN / PNP switch. The product can transfer the collected pressure signal into standard current and pressure signal output. The display and connection can rotate freely within 180 degrees so that it can be easily installed.
Applications
Gas-liquid dual-capable can be used in : pump control, storage tank monitor, liquid level control, filter blocking and monitor, leakage surveillance.
Industrial process testing and control
Self-controlled and constant-pressured water supply in building
Petrochemical, environmental protection, water conservancy, light industry, machinery, metallurgy
Measuring and control in other systems
