LKM456 Temperature/humidity probe with 0...10V output
The LKM456 is an outdoor temperature/humidity probe with integrated transmitter and two voltage outputs 0...10V. It can be used to measure temperature and humidity values in and on buildings, plants and control cabinets as well as outdoors. It is suitable for direct connection to evaluation devices with voltage input such as PC cards or PLCs. The sensor is supplied fully calibrated. Minor corrections can be carried out on site by means of two controllers.
The temperature range can be changed customer-specifically with a PC via the built-in serial interface. In addition, the temperature, humidity in %r.H., dew point in °C and absolute humidity in g/m³ can be displayed. The optional communication interface S1 with adapter A1 is required for this.
When entering the temperature measuring range, please note that it is between -30 and +85°C. The minimum range is 20°C.
The measuring range for relative humidity is always 0...100%.
