Smart 4-20mA 0-5V Electrical Pressure Switch with No Nc Switching
SPS pressure switch offers pressure monitoring and control in
liquid and gaseous media. The SPS is applied in general industrial
applications such as in mechanical manufacturing, in machine tool
systems, in hydraulic and pneumatic systems, for pressure
monitoring and control and for pumps and compressors. It is
pressure switch, transmitter and display in one device. In its
standard configuration it has optional two switching outputs (PNP
or NPN), an analog output signal (0...20mA| 4…20 mA or 0...5V| 0…10
V) as well as with RS485 Link.
Whole stainless steel housing and the core high accuracy diffused
silicon pressure sensor ensure good accuracy measurement of
excellent long-term stability. WNK SPS has various functions
including current or voltage + PNP +MODBUS outputs, NO &NC
function, switch delay, OLED display, display turnable 180° and so
on, providing easy installation and pressure control.
