Our products are rated in "% of reading" - like deadweight testers - but unlike deadweight testers, they're not affected by ambient temperature (or local gravity).
To calibrate short temperature sensors is always a challenge. The higher temperature you want to calibrate, the more difficult it becomes.
All digital pressure gauges are "temperature compensated" but when you study the fine print, you will find that temperature can still have a big effect on accuracy.
As the name implies, they are sensors used to measure temperature by correlating the resistance of the RTD element with temperature.
RTD element is made from a pure material which has a predictable change in resistance as the temperature changes
This is depending on the accuracy you expect to gain from the calibration. If sensors are having a diameter of more than 9 mm the heat loss up through the sensor is becoming very high.
Uncertainty has to be considered for each individual test done by the customer themselves. There are a number of variables in the uncertainty calculation that Crystal does not control such as the physical setup, operational procedures, and ambient environment.
