Reinventing the calibration process
What if you could eliminate product quality risk due to inaccurate process temperature measurement between calibration cycles?
ifm’s “Calibration Check” technology provides real-time continuous monitoring of instrument accuracy and measurement uncertainty. A large, bright LED dome provides an immediate signal of any deviation from the user-specified tolerance.
What if your temperature instrument could reduce your total cost of ownership?
Initial purchase price of an instrument is generally only a small percentage of the total cost of ownership equation.
|Sensors/adapter/installation costs||Calibration cycle 4x/year (250$/sensor)|
|Initial calibration $180/sensor||Calibration cycle 2x/year (250$/sensor)|
ifm’s “Calibration Check” technology automates manual periodic calibration checks. By eliminating mistakes from manual measurements and hand-recorded values, you ensure accurate time-stamped quality records.
Typical periodic calibration verification cycle
- Install: It is necessary to install two identical units next to each other. Typically, both units are taffected by drift in the same way
- Remove: Periodically, remove a unit from service. Frequency depends on each user’s quality process
- Check: Check the calibration of the unit against a known standard. This is done in-house by the user or by third party labs
- Validate manually: Validate the results
- Document maually: Document the results
- Reinstall: Reinstall the unit
Automated continuous calibration verification with IO-Link
- Install: A single TCC takes the place of two standard transmitters
- Measurement: Measured process value sent to PLC via IO-Link for process control
- Document automatically: Via IoT port, record time-stamped PT and NTC measured values
- Check automatically: Automatically check documented values for drift
- Continue: This verification cycle continues without the need to remove the TCC from service
