-
sensor accuracy ±1.8 %RH at 23 ºC in the
range of (0 to 90) %RH
-
hysteresis < ±1 %RH
- non-
linearity < ±1 %RH
- temperature error: see diagrams in Annex 8
Dew-
point temperature: ±1.5 °C at an ambient
temperature of T< 25
°C and RH >30 %.
For details see diagrams in Annex 3 .
External temperature input (without probe):
± 0.2 °C in the range -90 °C to +100 °C
± 0.2 % of the measured value in the range
+100 ° C to +260 ° C
The precision of the device with the connected
temperature probe is determined by the above-
mentioned precision of input and accuracy of
the probe used.
Connection method (external probe):
Two-wire connection with the possibility of
compensation for the cable wire resistance. The probe
is terminated by a 3-pin M8 ELKA 3008V connector.
The method of interconnection is given in
Annex 2 .
The recommended length of probes Pt1000/E is up to
15 m, not longer than 30 m. It is recommended to use
shielded cables.
