Smart Differential Air Pressure Sensor Modbus 4-20mA Air Differential Pressure Transmitter

Differential pressure refers to the difference in pressure between two points in the system.

Differential pressure sensor is a device used to measure the pressure difference between two objects. Differential pressure sensor is a widely used sensor in industry and science.

Differential pressure sensors are widely used in textile workshop, boiler air supply, underground ventilation and other power, coal, spinning cotton box, dust removal equipment, industry pressure process control field.

Many factors need to be considered when installing a differential pressure sensor, such as protection class, supported fluid type and flow rate range, lateral temperature gradients and zero drift due to temperature changes. For optimum measurement results, install the transducer carefully following the guidelines provided by the manufacturer.

The causes may be: 1. unstable supply voltage. 2. Improper choice of installation location and external interference. 3. There is air leakage or obstruction in the pressure line. Solution: 1. Check whether the supply voltage is stable, if necessary, use a stabilized power supply. 2. Re-select the installation location to avoid external interference, such as vibration or electromagnetic interference. 3. Check whether there is air leakage or obstruction in the pressure pipe, repair or clean.
