Leak check to ensure water tight seal. If any leaking occurs, rework and lubricate as necessary.
If leak-free, your RTD sensor is ready to use with the nVision Reference Recorder.
a Note: Your nVision has the RTD100 module TCR set to Pt100 (385) Euro. Modify this setting in
Crystal
Control
if required.
Modifying.the.Base.Resistance.(Ro)
As with any measurement device, it is possible the sensor will drift over time or from extreme
temperatures.
The nVision allows a user defined offset to the 100Ω base resistance experienced
at 0ºC if needed to improve the performance of your sensor.
This feature can be found in
CrystalControl and can also be viewed under the
Summary pages on the nVision product.
Resistance.Temperature.Detectors.(RTDs)
Resistance Temperature Detectors (RTDs) are temperature sensors that contain a resistor that
utilize the predictable change in electrical resistance of particular materials over temperature.
Platinum elements have been used for many years in laboratories and industrial processes, and
have a reputation for range, linearity, repeatability and stability.
The selection strengths of RTDs,
or sometimes called PRT (platinum resistance thermometer) are their wide temperature range
(approximately -200ºC to 850ºC), accuracy (better than thermocouples), good interchangeability
between similar sensors, and long-term stability.
For further information about RTDs not cov-
ered in this section please refer to
