• LKM445/446 Indoor Temperature/Humidity Sensor
• LKM445/446 is a low-cost internal temperature/humidity sensor with a built-in measuring transducer and two voltage outputs.　This sensor allows users to measure temperature and humidity in buildings, factories, and switch cabinets.　The temperature sensor can be connected directly to an evaluation unit that also has a voltage input, such as a PC card or PLC, and is provided fully calibrated.　The accuracy of the LKM 445/446 sensor is +/- 0.5 °C and 3% relative humidity.　Two controllers are provided to allow users to perform minor corrections in the field.　This sensor is only suitable for use in enclosed spaces, so special care must be taken when placing the sensor.　There is a cable outlet on the back of the sensor, and a lateral cable outlet is available as an option.　This temperature/humidity sensor corresponds to the protection class and allows the user to switch the temperature range from -20 °C to 80 °C.
