Working Principle
The FTG20 uses a piezoresistive sensor. Pressure acts on the diaphragm to produce slight deformation, which is converted into an electrical signal through a Wheatstone bridge. The built-in circuit amplifies, linearizes, and temperature-compensates the signal, ultimately outputting a standard industrial signal.
This principle ensures high repeatability and low hysteresis, making it suitable for dynamic pressure measurement. Understanding the principle helps with correct installation and troubleshooting.
Installation Steps
Correct installation is key to ensuring measurement accuracy. Please follow these steps:
- Inspection and preparation: Confirm that the product model, range, and interface match the system, and prepare appropriate tools and seals.
- Mechanical installation: Screw the transmitter into the process connection, tighten with a wrench, and avoid excessive force that may damage the threads. It is recommended to install a buffer tube or shut-off valve between the pipeline and the transmitter.
- Electrical connection: Connect the power and signal wires according to the wiring diagram in the manual, paying attention to polarity. The shielded wire should be grounded at one end to reduce electromagnetic interference.
- Power-on inspection: After power-on, observe whether the output is normal and whether the zero point drifts. If abnormal, check the wiring and power supply.
- Calibration and commissioning: If necessary, perform zero and full-scale calibration, then slowly open the valve and put it into operation.
After installation, it is recommended to regularly check sealing and output stability.
Selection Guide
When selecting, consider the following factors comprehensively to ensure the FTG20 meets actual working conditions:
- Measurement range: Choose a range 1.5 to 2 times higher than the maximum working pressure to avoid overload.
- Output signal: Choose 4～20 mA, 0～10 V, or RS485 according to the control system interface.
- Process connection: Match the on-site pipeline thread specification, such as G1/4 or M20×1.5.
- Medium compatibility: Confirm that the wetted material (such as stainless steel) is compatible with the medium to prevent corrosion.
- Environmental conditions: Consider temperature, vibration, and protection class; select an IP67 model if necessary.

Common Problems and Maintenance
The following lists common problems and handling suggestions for daily maintenance reference:
- No output signal: Check the supply voltage and wiring polarity, and confirm whether the power supply is normal.
- Large output fluctuation: Check shielded grounding to eliminate electromagnetic interference or pressure pulsation.
- Zero drift: Recalibrate the zero point and check for overload or excessive temperature changes.
- Leakage: Check seals and threaded connections, and replace the sealing ring if necessary.
Regular maintenance can extend the service life of the transmitter. It is recommended to check every six months.
