Pressure & Vacuum -Calibration Repair, Recalibration & Certification
Laboratory pressure calibration specialists offer comprehensive solutions for maintaining and calibrating pressure gauges, indicators, and sensors. They provide excellent maintenance and calibration services, with certification traced back to national standards. They offer full recalibration services on all instruments with quick turnarounds to minimize downtime. They can handle basic calibration to servicing and repair, including replacement equipment. Pressure calibration can be performed in their permanent laboratory or on-site at the customer's location. They have some of the most precise pressure calibration equipment available, encompassing a wide range of disciplines.
Our technicians have experience in various industries, including offshore oil, gas, chemical, and petrochemical industries. They can accurately test and measure all types of gauges using traceable hydraulic calibration equipment, conduct rising and falling pressure tests, and offer minor repairs and readjustments. They can calibrate vacuum gauges up to -1bar using a traceable pressure calibrator. They also calibrate pressure chart recorders using traceable hydraulic pressure equipment and precise temperature calibration equipment.
Pressure gauges are essential in various settings, such as pressurized bottles, home gas appliances, and natural gas border stations. Calibration laboratories use three types of pressure measuring instruments: manometers, pressure transducers, and pressure transmitters. Manometers are complete mechanical instruments that indicate pressure units and can be analogue or digital. Pressure transducers transform the applied pressure-proportional analogue electrical signal from the measured pressure, and pressure transmitters are units made up of a conditioning and amplification module for the transducer signal and a pressure transducer. Accuracy classes define the accuracy of pressure measuring instruments, with limits of permissible error as per EN 834-1/6. Dead Weight Testers and Pressure Calibrators are common calibration equipment. Dead weight testers apply pressure on a fluid to check the accuracy of pressure measuring instruments, while Pressure Calibrators are digital instruments that can be handheld or benchtop and can be intrinsically safe for use in explosive environments. Calibration procedures involve meeting metrological requirements, stabilizing the instrument, checking the gauge's condition, and conducting initial checks.
