DOL 104 humidity sensor 0-5V

Manufacturer item no.: 140274

The DOL 104/140274 is a high precision relative humidity sensor. The sensor has an analogue output with very low output resistance and full protection against short circuits and cable faults. The special sensor element and the integrated filter enable use in livestock stables with a constantly high level of humidity. The sensor is controlled by a microprocessor and has a two-color light emitting diode (LED) to indicate operational status and to diagnose faults. A protective cap is also available so that the sensor does not have to be removed when cleaning the barn. However, this sensor is also suitable for other industrial applications and is easily adapted to all types of asset management systems.
