Installation and Wiring Steps

Correct installation and wiring are the foundation for ensuring the long-term stable operation of the B 61-300. Please follow the steps below:

  1. Confirm that the pressure in the pipeline has been released and close the shut-off valve.
  2. Screw the instrument process connection into the pipeline interface and tighten it with a wrench, avoiding excessive force.
  3. Connect the power and signal lines according to the wiring diagram in the manual, paying attention to polarity.
  4. After power-on, check whether the output current is normal and perform zero calibration if necessary.

Wiring Precautions

  • Use shielded cables and ground them at one end.
  • Avoid laying cables parallel to power cables.
  • Ensure the supply voltage is within the range of 24 V DC ±10%.

Calibration and Maintenance Points

Regular calibration can maintain the measurement accuracy of the B 61-300. It is recommended to calibrate once every 12 months.

  • Zero Calibration: Under no pressure, adjust the zero potentiometer so that the output is 4 mA.
  • Full-Scale Calibration: Apply full-scale pressure and adjust the span potentiometer so that the output is 20 mA.
  • When cleaning, use a soft cloth dipped in neutral detergent and avoid corrosive solvents.
  • If reading drift or abnormal output is found, first check the wiring and power supply.

Common Questions and Selection Recommendations

When purchasing the B 61-300, please choose the appropriate model according to the actual medium temperature, pressure range, and explosion-proof requirements. Common questions include:

  • No output signal: Check the power supply and polarity.
  • Large reading deviation: Recalibrate or check whether the process connection is leaking.
  • Display fluctuation: Confirm whether the medium is pulsating and install a damper if necessary.
