The air humidity meter can be connected to up to four external temperature and humidity modules. The temperature measurement range at the sensors by the air humidity meter 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 air humidity meter via a power supply of 110 ... 220V AC. The integrated sensor can supply the connected sensors in the air humidity meter 12 or 24V DC supply.
As soon as the sensors are connected, they are automatically recognized by the air humidity meter. The communication between the sensor modules and the air humidity meter takes place via an analog 4… 20-mA signal. If several sensors are connected, the average reading of all sensors is displayed on the air humidity meter. The air humidity meter is used, for example, in event halls, restaurants or in public buildings to monitor ambient conditions.
Both the air humidity meter and the sensor module are mounted on a wall. If necessary, the air humidity meter can be mounted on a monitor bracket with the mounting dimensions 75 x 75 mm. This allows the air humidity meter to be ideally aligned. The air humidity meter can optionally be equipped with an ISO calibration certificate.
