Pressure Calibration - The Use of Equipment Calibration in Industry Production


Do you know that pressure calibration equipments are highly used in industry production? There are high accuracy sensors and equipments available which are suitable for calibrating other instrumentation like pressure gauges, pressure transducers and transmitters. Some of these calibrators are chosen for meteorology, laboratory, and factory use.

There is a huge line of pressure gauge calibration products used for various purposes. Whether they are used for increasing the volume of industrial production or for some other applications, they are quite essential. Following are some of the widely used such equipments:

1. Pneumatic Calibration Hand Pumps

These equipments are used for generating precise air pressure set-points manually for calibrating pressure instruments with a pressure indicator.

2. Digital Test Gages

They are used for fitting to the top of pneumatic or hydraulic calibration hand pumps to measure precise pressures.

3. High Pressure Calibration Hand Pumps

There equipments are used with a view to generating calibration pressures with fittings for rising a test gage or connecting to a indicator.

4. Secondary pressure standards

In calibration laboratories or instrumentation workshops, these devices or equipments are used for displaying high accuracy readings.

5. Hand held precision manometers

They are often used as a part of a pressure calibration kit. They are battery powered and can show a choice of pressure units.

6. Pressure Calibrators with Electrical Measurement

Pressure calibrators work as voltage and current measurement to display the output signal of the pressure transducer or to transmit under test along with pressure reading.

7. Calibration Standard Pressure Sensors

These equipments are with very high accuracy. They are often used as a secondary reference standard in calibration standard laboratories.

There are some most common pressure and vacuum calibration instruments like Calibrators, Gauges, Differential Pressure, Manometers, Pressure Controllers, Monitors, Transducers, Transmitters, and Vacuum Gauges.

Most Common Type of Pressure Gauge:

One of the most common types of pressure gauge is the plunge or pencil type. Though such types of equipments are calibrated but some cheaper ones are not calibrated. Please remember that a common plunge type gauge, that you buy will be accurate to + or - 3 psi when it is new. Normally, the accuracy of such type of gauges is affected by temperature, and humidity.

Don't Compromise With the Quality:

Irrespective of the type of gauge you choose, there are high as well as low quality gauges available. Many inexpensive gauges can not be calibrated. And if the reading is inaccurate, the gauge will be worthless. Therefore, you should spend a little more and get a quality pressure gauge that can be calibrated for better accurate results. You should not compromise with the quality keeping in mind the price of the equipments.

You will come across many pressure calibration services where you can choose for calibrating pressure instrumentation. If you wish to get huge production, you need to get your pressure equipments calibrated regularly. Your pressure measurement equipment may need to be calibrated regularly in order to stick to quality system standards like ISO9000.
