5.2 Operation conditions
Maximal temperature at the end of sheath cable:
Ambient temperature at the area of flying leads outcome,
connection of connection or compensating wires, connection of
connector or sensor head cannot exceed 100 °C (120 °C short-
term).
Measured media:
Applicability of the sensors for the specific medium depends on
the stem material of the sensor.
Completion of measuring insert (S1, S2, S3, S4, S5) with
temperature sensors:
Listed versions can be combined as a spare part with
temperature sensors ModuTEMP
®
70.
Humidity:
Sensors with fiberglass insulation of wires must be used in
a dry environment.
5.3 Metrological parameters
Temperature sensors FlexiTEMP
®
60 can be supplied:
- as sensors with calibration,
- as sensors without calibration.
Tolerance limits of accuracy classes are listed in EN 60751
for RTD and EN 60584-1 for TC. For thermocouples with
connected wires according to EN 60584-3, allowed tolerance
of thermoelectric voltage is increased by deviation of
additional compensation/extension wires with accuracy class
consistent with the primary TC. The initial tolerance is related
to the initial calibration of the sensor. Drift of the sensor (RTD)
meets the requirements of EN 60751, Sec. 6.5.3. To ensure
accuracy of measurement, it is necessary to calibrate sensors
periodically according to the operating parameters. Sensors
can be supplied with calibration at several temperature points,
according to customer requirements.
