Periodic recalibration of precision measurement instrumentation is recommended to ensure product performance accuracy, while extending useful service life. Recalibration is particularly important for sensors that are continuously deployed in challenging environments. Sherborne Sensors offers full in-house recalibration services for all types of inclinometers, accelerometers, force transducers and load cells, both Sherborne Sensors product and other manufacturers' models, within the ranges defined below:

Inclination: ±360° to within 5 seconds of arc

Acceleration: Up to ±20g to within 0.001g depending on range

Calibrations up to ±1g using a precision rotary table

Calibrations over ±1g using a precision centrifuge

Force/Load: Tension and Compression 10 gm (0.35 oz) to 300 tonnes (660,000 lbf)

While it is recommended that sensors receive recalibration every 12 months, certain factors, as detailed below, may suggest the need for more or less frequent service:

• Environmental conditions
• Frequency/duration of use
• Level of accuracy required
• Importance of measurement data
• Company quality assurance (QA) procedures
• International/national/local regulations

Specialized calibration engineers, under the direction of the Sherborne Sensors Quality Department, perform all recalibrations, following internationally recognized procedures. A test report is produced, which defines product reference, serial number, listing of all certified standards, as well as certification numbers and a chart of all measured values and related errors. Environmental conditions during recalibration are also clearly defined, including temperature, humidity and gravity. In cases where a transducer is showing performance after recalibration that is below original specification, a defect report will be issued, highlighting the deviation and, where appropriate, a cost to bring performance back to its original specification. Finally, all Sherborne Sensors recalibrated transducers are supplied with a calibration certificate, traceable to international standards.

In addition to recalibration, sensors and indicators are also routinely pre-calibrated at the Sherborne Sensors facility, complete with connector/cable/accessories already fitted and -where applicable -pre-programmed display instrumentation, to form a complete measurement system with optimal performance characteristics. An overview of standard system level components and accessory offerings may be found on our web site.
