These M18 and M30 sensors should be considered as part of the traditional range of capacitive sensors with the difference that electronic portion is completely separate from the sensing part which is in the form of an extension and can withstand temperatures from -200°C to +250°C. These products are used to control the levels of hot materials such as liquids, oil, powder and plastic granules. They also sense solid metallic and non-metallic bodies positioned in areas of high temperature. The connecting cable between the sensor and the amplifier must be of standard length (2mt or 5mt). It is connected to the sensor and it is provided with a shielded connector for connection to the amplifier.
