Temperature and humidity sensor for open space as a replacement sensor for the EM 524 89 device series. The sensor can only be used in conjunction with the FAG 524111 sensor housing. This means that the sensor can be replaced without the hassle of knocking the surface open. The sensor cable can be extended to up to 50 m using a two-core cable with a cross-section of 1.5 mm2, which is designed for mains voltage. A shielded cable must be used when laying in cable ducts or near power lines.
