What is a differential pressure gauge? How does it work? Let’s explore the details with Tân Thanh in the article below!
1. What is a Differential Pressure Gauge?
A differential pressure gauge is a device used to measure the difference in pressure between two areas with different pressure levels. This includes monitoring pressure differences between rooms, functional zones in factories, or machinery.
Most modern differential pressure measuring devices come with features such as data hold function, LCD or LED displays, internal memory, and the ability to transfer data to a computer for evaluation and recording.
Depending on the model, a differential pressure gauge may have an analog output. Therefore, readings from the gauge can be used to adjust or monitor various systems. It is essential to consider different measurement ranges and whether the device is suitable for measuring gases or liquids.
If a differential pressure gauge is used with liquids, it should only be used with non-corrosive fluids like water or oil. It should not be used with strong acids or corrosive substances such as bleach or hydrochloric acid.
2. How does a differential pressure gauge work?
When the pressure at the inlet (high pressure) is greater than the pressure at the outlet (low pressure), the sensor component shifts. This movement drives the actuator rod (which could be made of steel, liquid, magnet, etc.) into operation.
This force rotates the gauge needle in the direction of the arrow, displaying the pressure difference on the gauge face. This allows operators to easily monitor and check the pressure difference at the required measurement points.
3. The 4 most commonly used differential pressure gauges today
- Fixed Probe Devices: Used for simple daily measurements.
- Devices with Connectable Probes: Depending on the probe type, these can measure not only differential pressure but also other parameters.
- Smartphone-Operated Devices: Measurement results are processed and read via a smartphone or tablet.
- Probe Devices: Optional probes with differential pressure sensors are used to measure pressure and flow rate.
4. How to use a differential pressure gauge
- Proper Installation: To ensure accuracy, the gauge should be installed vertically.
- Calibration After Installation: If the gauge needle is not at 0 Pa, you can adjust it to the correct position using the “zero reset” screw.
- Choosing the Right Installation Location: Avoid installing the gauge in areas with strong vibrations or where ambient temperatures exceed 60°C.
- Correct Usage Position: The gauge is calibrated with a vertical dial face, so it should be used in this position for the most accurate readings.
With various measurement ranges, differential pressure gauges are widely used in many industries, including pharmaceuticals, healthcare, HVAC, microelectronics, aerospace, environmental engineering, and biotechnology.
