Modern pressure measurement systems in industry usually require the use of a pressure transducer, which is a sensor that converts actual pressure into an electrical signal. There are several different types of pressure transducers, but one of the most common is the Wheatstone Bridge Strain Gauge transducer which uses signals from changes in the strain gauges to report pressure values. Pressure transducers are generally available with three types of electrical output: millivolt, amplified voltage and current limited (4-20mA), all with their relevant advantages and disadvantages to differing applications within industry.
The long-term performance and accuracy of pressure transducers is critical to control systems in many industries (food processing, oil and gas platforms utility plants for example). The nature of these industries means that operational environments are quite harsh and unfriendly causing the performance and accuracy of transducers to shift over time. To prevent pressure transducer in-accuracies requires stringent planned preventative maintenance regimes including, periodic verification, calibration, and maintenance.
Calibration of pressure transducers is a complex process and requires the use of a device or devices that can generate and measure pressure via electrical signals. Calibrationhouse has access to these devices and many years of knowhow which allow us to offer this service across the UK.
