FAQs

What does a pressure calibrator do? ›

A pressure calibrator is a high-precision pressure measuring device capable of verifying (or calibrating) the pressure reading of another pressure measuring instrument. These instruments are also called pressure standards. The pressure calibrator must be more accurate than the instrument being calibrated.

The pressure calibrator must be more accurate than the instrument being calibrated. Traditionally, the calibration ratio is 4:1. This means that the pressure calibrator is 4 times more accurate than the device it is calibrating. A pressure calibrator can also have additional features simplifying the calibration.

Druck is a division of Baker Hughes. We are an energy technology company.

The Druck product name has long been associated with precision pressure sensors and related test / calibration instruments. Druck's product range includes relatively low cost OEM devices to very high accuracy resonant silicon barometric sensors measuring pressures from less than 0.015 psi to 15,000 psi.

A calibrator is an equipment used to adjust an instrument accuracy, often associated with a specific application. The most sophisticated industrial equipment will not be very useful unless it is calibrated.

More often than not, pressure gauge calibration is necessary at least once a year. Calibration doesn't just check the precision of the tool, it tests the traceability of the measurement. Upon completion, the technician produces a report which shows the measuring errors before and after the calibration.

Druck's parent company, Baker Hughes, is an energy technology company, employing 54,000 people, that provides solutions to energy and industrial customers worldwide.

In 2002 Druck was acquired by GE Sensing which is a part of GE Measurement & Control Solutions ( www.gemeasurement.com ) which is an affiliate business of General Electric. Its worldwide headquarters is located in Billerica, Massachusetts.

Named after the German word for 'pressure', Druck was established in 1972 by two pioneering entrepreneurs, Mike Bertioli and John Salmon. Their vision was to invent and commercialise the world's first silicon-based piezoresistive pressure sensors and become an industry leading multi-million-dollar business.

Pressure Indicators is a broad term covering any instrument that senses pressure and records it. A pressure gauge is normally a mechanical device that senses pressure and records or converts it physically into a reading on a scale. So a pressure gauge is a pressure indicator.

What is a pressure sensing device? ›

A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal.

A pressure transmitter is used to measure the pressure value of a fluid or gas. This information can be used in a variety of applications, including industrial systems and processes, and process control.

These process calibrators are designed for easy generation and measurement of temperature, pressure, frequency and electrical signals. These documenting instruments have been developed for testing and calibration of numerous process signals as well as their generation and measurement with high accuracy.

Calibration Procedure: Connect the pressure gauge to the reference standard and record the reading. Compare the reading with the reference standard and adjust if necessary. Repeat the process at various points within the calibration range.

ADAS calibration involves aligning these sensing devices in your car so that they function properly. A dynamic calibration process will require the technician to take your car out for a drive, while a static calibration process uses specialist tools to calibrate the ADAS while your car is stationary.

Pressure gauge calibration is the process of verifying the accuracy of a pressure gauge against a known standard. This is done by comparing the output of the gauge to a reference gauge or by applying a known pressure to the gauge and measuring its output.
