Normally six sensors are recommended for each motor, Two per Phase. Unlike on/off devices, It allows continuous measurement of winding temperature. These sensor are sandwiched between the windings of Motors/Generators. The Pt-100 BTDs are used widely to monitor the Bearing temperature of Electric Motors and AC Generators (Alternators). Motor Winding RTD Temperature Sensors are used to measure winding temperature of large Motors, Generators etc. Output of BTD is used in similar way like RTDs. These averaging type sensors are used in electric motors and generators for continuous sensing of the temperature and provide for consistent thermal. They are mostly housed in a metal stud which is fitted on bearing housing on tapped holes. Temperatures upto 500 o C can be monitored and controlled with these BTDs. This signal is given to a temperature indicator / controller for achieving the desired measurement and control. Hot spots T2+10 (☌) If you are interested in details, this is based on IEEE 112 and NEMA MG1. Calculate average total temperature of the winding T2 (☌) 5. The output signal of BTD is a resistance signal, which varies linearly with the temperature. Stop the motor and read resistance for the same pair of leads (into 60 seconds of power cut off). The Pt-100 Bearing Temperature Detectors (BTDs) are used for temperature sensing, measurement and control of these bearings. Probe IP68 Digital Temperature Transmitter Input Type For Petroleum. Contact us today toll-free at (800) 991-9093 to request a quote for your specific temperature sensor needs.In many applications the temperature of Bearing / Bearing Housing has to be monitored continuously. We are good quality supplier of RTD Temperature Sensor, Stator Temperature Sensor, Motor Winding RTD from China. This RTD are generally flat type in construction and are available in various sizes. Temp-Pro can supply you with a customized stator winding RTD solution to fit your needs. Motor Winding RTD Temperature Sensors are used to measure winding temperature of large Motors, Generators etc.
Stator winding RTDs can be manufactured with custom holes, additional elements, different coating materials, and dual sensors-all customized to meet the performance requirements of our most demanding customers. Temp-Pro offers a variety of stator winding RTD options, including rear and side exit, as well as paddle sensors (alternatively known as Gas or Air RTDs). However, the second element also allows for temperature sensing both on-site as well as remote monitoring, such as from a control room or monitoring station. Their design is similar to a long bar or sword and they include either a thin film measuring. They are mounted in the slot of the stator close to the copper windings. In its duplex configuration, the RTD has a second element that serves as a backup sensor in the event of a severe increase in temperature that leads to damage. Slot resistance thermometers in short SRT - are electrical temperature sensors for measuring and / or regulation of the winding temperature of electrical motors or generators. Such temperature data can be used to assess the reaction to potential- or impending-damage to its insulation or other components.ĭuplex stator winding RTDs can provide extra temperature sensing protection when properly installed in motors and generators. These temperature sensing devices offer motor manufacturers an added element of protection since they RTDs can sense increases in temperature, measured over a period of time. Stator winding RTDs are also found in vehicles, devices, and other industrial machinery. The application of stator winding RTDs include rotating machinery components such as generators, compressors, pumps, or gearboxes. The flat laminated sensors are also use in generators to measure winding temperature, allowing for a continuous measurement that supports potential early warning alerts. Stator winding RTDs are a popular solution for OEMs of electric motors, usually inserted between the coils in the stator of a motor. Our thin-profile stator winding RTDs can be customized to meet specific dimensions and applications in your electric rotating equipment
