ICO 52 are programmable digital panel meters 72 x 24 mm for temperature, process voltage and process current measurements in 10,000 points. They can be used together with temperature sensors, either resistive probes Pt or thermocouples. It is possible to change the configuration of measurement type, range, limits and scaling.
The configuration of these parameters is protected against any inopportune modifications.
- Panel meter size: 72 mm x 24 mm
- IP65 protected
- Measurement, display and scaling of:
- Temperature with Pt100, Pt1000 probes or thermocouples (7 types)
- Process voltage and current (0-10 V, 4-20 mA)
- Resistance
- 9 different power supplies available

Display in °C or °F.
(1) For a defined type of sensor, the commutation of range and the change of resolution can be automatic.
Measurement range extendable.
(2) Accuracy given without reference junction.
The typical error brought by the reference junction (AN8002) is 0.3°C.
Further features
| Measurement hold | Short-circuit on the rear panel |
| Scaling | The value is to be entered using keyboard, while the value of measurement corresponding can be is introduced of the same way, is measured by the instrument. This possibility is very interesting for error corrections on temperature ranges. |
| Sampling rate | 2.5 samples / s |
