4-20mA RS485 Smart Sanitary Pressure Sensor Switch with PNP/NPN
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.
Features: - PNP switching, voltage and current outputs
- Switching points settable
- Switching can be set normally open / normally closed
- Analog output span settable
- Offering Switching delay function
- Support MODBUS
- Displaying pressure peak value and environment temperature
- Various analog output ways available
- OLED display
- Display turnable 180°
- Housing with electrical connection against process connection
rotatable 330°
