RS485 Industrial Pressure Switch Transmitter with Rotable OLED Display
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.
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°
