Drift monitoring even between calibration cycles
Contents
Regular calibration of temperature measurement points is particularly required in the food and pharmaceutical industries and often involves interrupting the process. Added to this is the uncertainty associated with undetected drift between calibration cycles.
The GV4 MiniTherm temperature transmitter, optionally equipped with the self-monitoring function package, offers a solution here. Temperature measurement is carried out via two Pt100 sensors, the distinctive feature of which is that their physical design ensures opposite drift behaviour. With each measured value, the signal difference (ΔR) is continuously monitored, so that exceeding a threshold value (ΔRS) can be detected immediately and the drift warning is triggered.
Double-Pt drifting in opposite directions
Highlights
- Complete drift monitoring, even between calibration cycles and across the entire temperature range
- No periods of operation with undetected erroneous readings
- The permissible drift (ΔRS) can be individually set by the customer
- High measurement accuracy
- Redundancy in the event of a sensor failure
