Rotor Temperature Monitor RTM-200 Monitoring solution Contactless temperature monitoring High speed, allowing rotor instantaneous temperature Rotor Temperature monitoring during operation • Reduced Ø 4mm probe diameter for insertion in small ventilation holes Multiple installation depth ranges: 50mm to 190mm 190mm to 330mm 330mm to 470mm 470mm to 610mm Integrated Modbus RTU slave for digital interfacing 4 to 20mA current output for analogue interfacing Typical applications Measuring temperature range 0°C to 200°C Hydrogenerators Windturbines Gearless millsdrives DESCRIPTION The RTM-200 is a contactless temperature sensor especially designed for rotor monitoring in generators and motors. The probe of the sensor is designed to be inserted in ventilation holes of such machines. This cutting edge technology sensor uses the latest technics for remote temperature measurement. This principle allows the probe diameter to be as small as 4mm. Then the well established know-how of MC-monitoring in digital signal processing has allowed to integrate filtering and linearization of the raw signal in order to obtain a accurate and linear output that is proportional to the measured temperature. Additionally, the RTM-200 integrates a Modbus RTU slave to perform quick analysis of the rotor temperature as well as the sensor itself thanks to the MCm Sensor Manager software. The adjustable installation depth allows the sensor to be installed in various size of machines with stator cores thickness comprised between 50mm and 610mm according to the order code. The installation of the sensor can be either for short term measurement thanks to the integrated permanent magnets or for long term measurement with additional adhesive compound. Even in case of permanent installation the sensor can be easily withdrawn from the holder for maintenance.
