CPS31D Product Overview
CPS31D is a pressure transmitter used for industrial process measurement, widely applied in fields such as water treatment, petrochemicals, power, and HVAC. Its core function is to convert pressure signals into standard electrical signal outputs, facilitating acquisition and processing by control systems such as PLC and DCS.
This product typically features high precision, anti-interference, and good long-term stability, making it suitable for continuous operation under complex working conditions.
Core Technical Parameters
The following table lists the typical technical parameters of the CPS31D. For specific values, please refer to the manual supplied with the product or the official data sheet.
| Parameter | Typical Value | Description |
|---|---|---|
| Measurement Range | 0~0.1MPa to 0~60MPa | Selectable according to working conditions |
| Output Signal | 4~20mA / 0~10V | Supports two-wire or three-wire system |
| Supply Voltage | 12~36V DC | Standard industrial DC power supply |
| Accuracy Class | ±0.5%FS | Including linearity, hysteresis, and repeatability |
| Process Connection | G1/2, M20×1.5, etc. | Various threads available |
| Protection Rating | IP65/IP67 | Adapts to on-site environment |
Selection Points
1. Confirm the Measured Medium and Range
- Clarify whether the medium is gas, liquid, or steam, and whether it is corrosive.
- It is recommended to leave a 1.5~2 times margin for the range to avoid overpressure damage.
2. Match Output and Power Supply
- If connecting to a PLC analog module, prioritize 4~20mA output.
- Confirm whether the supply voltage matches the loop load.
3. Choose Process Connection and Material
- Select G1/2 or M20×1.5 thread according to the on-site interface.
- For corrosive media, stainless steel or special diaphragm materials should be used.
Installation and Commissioning Steps
- Shut off pipeline pressure and confirm the system is depressurized before installing the transmitter.
- Connect the power and signal wires according to the wiring diagram in the manual, and note that the positive and negative poles must not be reversed.
- Slowly open the valve and observe whether the output signal changes linearly with pressure.
- If there is zero drift, calibrate it through the zero adjustment potentiometer or handheld communicator.
Common Faults and Maintenance
- No output signal: Check the supply voltage, wiring polarity, and fuse.
- Large output fluctuation: Check for medium pulsation, grounding interference, or blocked impulse piping.
- Zero offset: Re-zero, and if necessary, check whether the diaphragm is deformed.
- It is recommended to perform calibration and visual inspection every 6~12 months.
