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 cable, “Grove – servo splitter – 20cm – 5pcs“.
- 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 the “Plastic Joiner” might not be needed, but the one I got lying around fit perfectly with “Connector PCF-02” as it 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 can fit the “Connector PCF-02”. In the end you end with:
