(*)
(*)
During battery charging temporary measurement
inaccuracy can occur.

t
63
< 6 min, t
90
< 15 min (temperature step
20 °C,
air circulation approx. 1 m/s)

U0121M ________________________________________
Measured values:
2 x temperature sensed by an external COMET
Pt1000/E series probe
Temperature range:
(-20
0 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 compensation of the error caused by the cable
resistance. The probe is provided with a 3-pin M8 ELKA
3008V connector. Its connection is shown in
Annex 2 .
