Response time:
Is determined by the response time of the used probe (it
valid if
Measuring interval is set to 1 s).
Display resolution:
0.1 °C, 16 bits A/D converter
Recommended calibration interval:
2 years
U0121, U0141, U0141T ____________________________
Measured values:
2 x or 4 x temperature sensed by an external COMET
Pt1000 series probe
Temperature range:
(-200
to +260) °C, Pt1000/3850 ppm sensor
Measuring current: approx. 0.5 mA with pulses of approx.
60 ms length
Input accuracy (without probes):
±0.2 °C in a range of (-200 to +100) °C
±0.2 % of the measurement value in a range of (+100 to
+260)
°C
The accuracy of the device with a temperature probe
connected to it is determined by the above input
accuracy and the accuracy of the probe employed.
Connection:
Two-wire connection with the possibility of compensating
the error caused by the resistance of the cable wires.
The recommended length of the probes is up to 15 m,
the length must not exceed 30 m. It is strongly
recommended to use shielded cables.
Models U0121, U0141 are intended for probes of the
Pt1000/E series terminated with a 3-pin M8 ELKA
3008V connector. The connection of the connector is
shown in
Annex 2 .
Pt1000/0 series probes without a connector are intended
for the U0141T model. They are connected to a pluggable
terminal block, max. wire cross-section: 1.5 mm

.
Response time:
Is determined by the response time of the used probe (it
valid if
Measuring interval is set to 1 s).
Display resolution:
0.1 °C
Recommended calibration interval:
