Which calibrations are offered by ifm?
ifm’s calibration laboratory offers ISO, A2LA and DAkkS calibrations. Newly bought sensors can be calibrated directly when you order them. Simply add the corresponding order code to the cart – see Pressure, Temperature, Flow or Analytical sensors. It goes without saying that ifm also offers recalibrations for sensors already in use.
Over time, almost every sensor is subject to stress. Without regular recalibrations, these influences can neither be perceived, nor compensated for. As a consequence, constant quality assurance is no longer possible.
To avoid such erroneous measurements, sensors must be checked at regular intervals to ensure that the specified tolerances of the quantity to be measured are met.
The International Organization of Legal Metrology (OIML) recommends specifying the calibration interval based on the following parameters:
Properties of the instrument | Operating conditions (tendency to wear and drift) | ||
The instrument manufacturer’s recommendation | Experience with similar instruments (individual or group calibration) | ||
Experience from previous calibrations | Requirements from customers, authorities and standards | ||
Extent of resulting damage due to lacking equipment |
The influence of the environment (temperature, moisture, vibration) | ||
Service life | Uncertainty in measurement |
Green = Initial choice of calibration intervals, Blue = Methods of reviewing calibration intervals |
We recommend performing a recalibration every 12 months. When critical control points (CCP) occur, the calibration interval may need to be shortened.
Recalibrations are only possible if the device is returned in a clean condition, without any adaptations attached (condition on delivery). Also, devices returned for recalibration must be accompanied by a completed Declaration of Decontamination.
