LKM445/446 Indoor Temperature & Humidity Sensor

The LKM 445 / 446 is a low cost internal temperature and humidity sensor which has an integrated measuring transducer and two voltage outputs. The sensor allows the user to measure the temperature and moisture levels in buildings, plants and switch cabinets. This temperature sensor can be connected directly to an evaluation unit that also has voltage inputs such as PC cards or PLCs plus is supplied fully calibrated. The LKM 445 / 446 sensors have an accuracy of + / 0.5 °C plus a relative humidity of 3%. two controllers are supplied enabling users to carry out minor corrections on site. The sensor is also only suitable for use within enclosed spaces and when mounting the sensor special attention should be paid to positioning the sensor. There is a cable outlet at the back of the sensor and a lateral cable outlet is an available option. This temperature / humidity sensor has a protection class and users have the option to switch to a temperature range of -20 to 80°C.
