Calibration : Independent, DAkkS-accredited temperature sensor calibration
Precise measurements lie at the core of all high-quality industrial production processes. Rely on consistently unambiguous and verifiable measurement results with our competent calibration services performed at the DAkkS-accredited calibration laboratory CENTROCAL GmbH. Our services cover everything from calibration during production to recalibration of our own and third-party temperature sensors, including metrological analysis and consulting.
As a wholly owned subsidiary, CENTROCAL GmbH is independent and has been accredited for the temperature measurement category since 1993. We calibrate temperature sensors in the temperature range from -196°C to +1,500°C. As one of only a few calibration laboratories around, we perform calibrations under inert gas atmospheres and calibrate multi-point thermocouples and Profi-Bus measuring chains. Sensors can also be tested and calibrated in accordance with CQI-9 and AMS 2750 at CENTROCAL GmbH.
Calibrations are performed under virtually entirely automated conditions at our calibration laboratory. The calibration laboratory fully complies with the requirements of DIN EN ISO/IEC 17025.
Why do temperature sensors need to be recalibrated on a regular basis?
Regular sensor recalibration is crucial for obtaining precise measurement results. By adopting a regular calibration schedule, you can avoid some of the inaccuracies that occur over the useful life of your sensors, as with all technical processes. Your car has its own inspection cycle (emissions test) to test emission of pollutants along with other factors. Temperature sensors need to be calibrated for the same reason not only during production, but also after one or two years in use, depending on the specifications from the customer’s quality assurance manual.
This is the only way to ensure unambiguous, verifiable measurement results.
However, recalibration cycles can be significantly extended by the use of certain finishing processes such as coatings.
Disassembling thermowells for calibration
In order to calibrate thermometers manufactured by us and third parties, we often first need to disassemble the thermowells. We do this as they are usually contaminated with foreign materials after use and this would prevent the calibration furnace from being used for future calibrations. Disassembly needs to be factored in when designing sensors and thermowells. At RÖSSEL-Messtechnik, we ensure everything is taken into consideration.
More information on the independent quality assurance of our calibration laboratory
In Germany, the Physikalisch-Technische Bundesanstalt (Federal Physical-Technical Institute) in Braunschweig and Berlin, is the country’s highest authority tasked with the realization and dissemination of units. It is partnered with national metrology institutes (NMIs) in other countries to ensure measurements are consistent around the globe. PTB is the technical supervisory authority for the laboratories organized by the German Calibration Service (DKD) and accredited by the German accreditation body DAkkS.
