Wiring

  • Make sure that the power supply is off while wiring.
  • Verify that the supply voltage variation is within the rating.
  • If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
  • In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
  • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
  • Incorrect wiring will cause problems with operation.

Others

  • Never remove the throttle.
  • Use within the rated pressure range.
  • Do not apply pressure exceeding the pressure withstandability value. The diaphragm will get damaged and correct operation shall not be maintained.
  • Do not use during the initial transient time (controller: 0.5 sec. approx, sensor head: 50 ms approx.) after the power supply is switched on.
  • Avoid dust, dirt, and steam.
  • Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
  • Do not insert wires, etc., into the pressure port. The diaphragm will get damaged and correct operation shall not be maintained.
  • Do not operate the keys with pointed or sharp objects.
