To can add a pressure sensor you need:
- Pressure Sensor Transmission – DC 5V G1/4 0-1.2MPa
- Connector Hose Fittings Tube Connectors (Notice it must be “PCF8-02”)
- Plastic Joiner 8mm (5/16)OD x 6mm ID x 50mm Long connect
- A duotight T-junction.
- Some Teflon tape.
The assembly is pretty straight forward, but you need to tighten it well and teflon tape do help. Please notice you must attach signal cord of pressure sensor till G8 and use 5v for power as 3.3v as the pressure sensor must have 5 volt to messure correctly. The “Plastic Joiner” I got lying around fit perfectly with “Connector PCF-02” as “Plastic Joiner” is just a bit bigger in inside diameter (6mm) than the common 8mm/5mm duotight tube. Else I am pretty sure the tubes from most osmoses water can fit the “Connector PCF-02”. In the end you end with:
