Installation and Wiring Guide
Installation Steps
- Confirm that the pipeline pressure is within the range, close the valve and release pressure.
- According to the process connection specification, wrap PTFE tape or use a gasket.
- Screw the transmitter into the port and tighten with a wrench, avoiding excessive force that may damage the housing.
- Ensure the cable entry faces downward or sideways to prevent water accumulation.
- After checking the wiring is correct, slowly open the valve.
Wiring Definition
- Two-wire system: Red wire to power positive, black wire to power negative (also serves as signal output).
- Three-wire system: Power positive, power negative, and signal output correspond to red, black, and yellow wires respectively.
- RS485: A to yellow, B to blue, shield wire to ground.
Selection and Maintenance Points
Selection Considerations
- Select the range according to the actual pressure range; it is recommended that the working pressure be between 1/3 and 2/3 of the range.
- For corrosive media, select compatible wetted materials (such as 316L stainless steel, Hastelloy).
- For explosive hazardous areas, choose intrinsically safe or explosion-proof types.
Daily Maintenance
- Regularly check zero drift and calibrate if necessary.
- Keep the housing clean and avoid blocking the pressure port.
- Check grounding reliability during thunderstorm seasons to prevent surge damage.
FAQ
What to do if the output signal is unstable?
First check whether the power supply voltage is within 12～36V DC, then confirm that the wiring is secure and the shield wire is well grounded. If the problem persists, it may be a sensor failure and requires factory repair.
