The Psychrometer can be connected to up to four external temperature and humidity modules. The temperature measurement range of the Psychrometer sensors is 32.0 ... 122.0 °F and the humidity measuring range is 0.0 ... 99.9% RH. The power supply itself is effected in the Psychrometer via a power supply of 110 ... 220V AC. The integrated sensor supply in the Psychrometer, can also supply the connected external sensors with 12 or 24V DC.

As soon as the sensors are connected, they are automatically recognized by the Psychrometer. The communication between the sensor modules and the Psychrometer takes place via an analog 4… 20-mA signal. If several sensors are connected, the average reading of all sensors is displayed on the Psychrometer. The Psychrometer is used, for example, in event halls, restaurants or in public buildings to monitor ambient conditions.

Both the Psychrometer and the sensor module are mounted on a wall. If necessary, the Psychrometer can be mounted on a monitor bracket with the mounting dimensions 75 x 75 mm. This allows the Psychrometer to be ideally aligned. The Psychrometer can optionally be equipped with an ISO calibration certificate.
