Diaphragm sealing system: Offers a variety of special materials and processhttps://heiautomation.com/contact-us/ connections, with a process temperature range of -70… +400°C
(-94…) +752°F)
Pressure switch: Through LED indicator lights and digital display screens
for conducting functional checks and displaying on-site information. Through personal computer operation and display, it provides a stainless steel housing and laser-engraved nameplate.
fundamental:Absolutehttps://www.facebook.com/profile.php?id=100087291657130 pressure and gauge pressure measurement: Measurement principle
Strain gauge sensor: Under the action of working pressure, the process is isolated.
The diaphragm deforms, and the resistance value of the pressure-sensitive resistor in the bridge changes, thereby converting pressure into a voltage signal (single-crystal silicon semiconductor technology). The voltage change of the bridge is measured and calculated to output.
Pressure switch: When the set pressure value is reached, the electrical PNP contact opens or closes. In addition, it also provides a 4…20 mA output signal.

- Usage Notes
- During installation, the pressure-sensitivehttps://heiautomation.com/ component of the transmitter should be axially perpendicular to the direction of gravity. If installation conditions are restricted, the transmitter should be fixed and then the zero position adjusted to the standard value.
- The residual pressure cannot be released, so the sensor zero position cannot be lowered. The best way to eliminate this cause is to remove the sensor and directly check if the zero position is normal. If it is normal, replace the sealing ring and try again.
- The output of the pressurized https://heiautomation.com/transmitter does not change. When the output of the pressurized transmitter suddenly changes, the zero position of the pressure-releasing transmitter cannot return. The cause of this phenomenon is very likely to be caused by the sealing ring of the pressure sensor.
- Whether it meets the power supply requirements; are there any wiring errors between the power supply and the transmitter and the load equipment. If there is no voltage on the terminal of the transmitter or the polarity is reversed, it can cause the transmitter to output no voltage signal.
- The shells of the pressure sensor and the transmitter generally need to be grounded. The signal cable lines should not be mixed with the power cables. The surrounding area of the sensor and the transmitter should avoid strong electromagnetichttps://heiautomation.com/about/ interference. The pressure sensor and the transmitter should be inspected and calibrated according to industry regulations during use.
- When users select pressure sensing covers and transmitters, they should fully understand the working conditions of the pressure measurement system and make reasonable choices according to needs, so that the system works in the best state and can reduce the engineering cost.
- The isolation sheet and the filling liquid inside the components “transmithttps://www.facebook.com/profile.php?id=100087291657130 to both sides of the measuring diaphragm. The measuring diaphragm and the electrodes on both sides of the insulating sheet form a capacitor.
- The pressure transmitter needs to be inspected once a week and tested once a month. The main tasks are to remove the dust inside the instrument, carefully inspect the electrical components, frequently verify the output current value, and ensure that the internal circuitry is isolated from the external high-voltage power supply.
