Indoor temperature/humidity probe LKM446
LKM446 Temperature/Moisture probe with output 0...10V
The LKM446 is a room temperature/humidity probe with integrated transmitter and two voltage outputs 0...10V. It can be used to measure temperature and humidity values in buildings, systems and control cabinets. 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 made on site by means of two controllers.
The cable outlet is located on the rear panel, a side cable outlet is optionally available.
The selection menu is available for configuration.
