How Differential Pressure Sensor Works

When a liquid or gas passes through the high and low pressure chambers, the force they exert on the two ends of the sensor creates a pressure difference. By measuring this pressure difference, we can learn about the flow of the fluid. Specifically, differential pressure sensors typically consist of two measuring membranes. As the fluid passes through the sensor, the force they exert on the two membranes causes the membranes to deform. The sensor will have some resistance or capacitance sensors installed inside the sensor to measure the deformation of the membranes. By calculating the change in resistance or capacitance, we can obtain the pressure exerted by the fluid on the sensor.

Differential pressure refers to the difference in pressure between two points in the system. The expression is ΔP=P1-P2.

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.
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 it in time.

The cause may be:
1. Improper selection of the installation location, resulting in the pressure sensor is subject to lateral force.
2. Temperature gradient or unevenness exists in the pressure line, causing sensor temperature error.
3. aging or damage to the sensor.
1. Re-select the installation position to avoid the influence of lateral force on the pressure sensor.
2. Ensure that the temperature of the pressure pipeline is uniform, and take insulation measures to reduce the temperature error.
3. Regularly check and replace the aging or damaged sensors.

The cause may be:
1. The temperature sensor is faulty or not calibrated in time.
2. Ambient temperature fluctuates greatly, exceeding the temperature compensation range.
1. Check whether the temperature sensor is working properly and calibrate it as required.
2. If the ambient temperature fluctuation is large and beyond the temperature compensation range, consider taking temperature isolation measures or using a pressure transmitter with a larger temperature range.
