PT1000 AA (immersion temperature sensor)
The immersion temperature sensor PT1000 AA for installation in an immersion sleeve is available for “heating and cooling” applications or for temperature-dependent control modes.
The PT1000 AA is connected to the Wilo-Stratos MAXO at one of the two analogue inputs AI1 or AI2, which have to be set to the connection type PT1000.
Technical data of the PT1000 AA:
- Tolerance class AA in accordance with DIN EN 60751
- Cable length 3 m
Tolerances PT1000 AA | |
|---|---|
Temperature in °C | Accuracy in °C |
10 | +/- 0.117 |
20 | +/-0.134 |
30 | +/-0.151 |
40 | +/-0.168 |
50 | +/-0.185 |
60 | +/-0.202 |
70 | +/-0.219 |
80 | +/-0.236 |
90 | +/-0.253 |
If the sensor cable is extended > 3 m, a “temperature correction value” can be set to compensate for the electrical resistance. (See the “Temperature sensor” section).
