A pressure calibrator is a highly accurate measuring device that’s used for calibrating the pressure in different instruments. These high-precision devices are usually more accurate than the instrument, with the conventional calibration ratio being 4:1.
They are used in laboratories, the automotive industry and in manufacturing.
Apart from calibrating pressure, they can also be used to measure the pressure output of specific instruments. Pressure calibrators often use a precision regulator that controls the pressure supply.
This leads to a highly accurate reading. Pressure calibrators can be custom-designed for specific purposes and accuracy of calibration. Portable units are commonly preferred, as they are easier to move around.
Handheld units are also available, though they aren’t as accurate as deadweight testers, which generate pressure by exerting force over a specified area. Deadweight testers don’t need to be connected to an external power supply either.
Such units are generally bulky and must be operated by a qualified professional. They are capable of calibrating pressure from as low as -15 psi to 75,000+ psi. Unlike a pressure gauge, a display indicator on the device often denotes the pressure reading.
Various kinds of pressure calibrators are used in different environments. Among all types, multifunction calibrators and deadweight testers are the most popular.
Handheld models are also available. The configuration, accuracy, and sensitivity of pressure often vary. High-end deadweight testers are equipped with highly precise sensors, which give a more accurate reading.
Pressure calibrators are available at different price points. Its price depends on many features, such as pressure range, type, brand, and accuracy. Some models retail for a higher price, especially those equipped with high-precision sensors.
A pressure calibrator is used in industries and research facilities to determine the accuracy of any device that includes a pressure gauge. They are used in laboratories, the automotive industry and manufacturing.
Some level of training is required for users to understand how to read and interpret the output signal from the sensor. Other licences or certifications might be required depending on the industry where it’s being used.
