Motor Winding Temperature Sensor

The measured and filtered temperature value is used for supervising and for monitoring the motor temperature.

Motor winding temperature sensor.

Each lift station can have a number of temperature sensors which are monitored by the station operator. Unlike on off devices it allows continuous measurement of winding temperature. Normally six sensors are recommended for each motor two per phase. Unlike on off devices it allows continuous measurement of winding temperature.

Pt100 ω rtds measure the lift station pump and motor bearing temperatures and the motor winding temperatures are measured by cu10 ω rtds. The time constant of the filter can be set with tempmfilt. Install between stator windings for continuous protection of motors and generators class f or h single and dual element rtd s thermocouple elements available see our stock list below or call to inquire dimensions to fit any machine 1 3 and 12 channel temperature monitors to complete the system. Thin film rtds are identical except for the size of the sensing element.

These motor temperature sensors are sandwiched between the windings of motors generators. The stator winding temperature detector rtd are used to measure winding temperature of large motors generators etc. When connected to a keb vfd similar to a kty sensor the pt1000 sensor can display accurate real time temperature data of the motor. The wire wound element extends through most of the body length and measures the average temperature of the winding.

If a handheld temperature detector were to read 129 c as in the example above the same concerns about the overall temperature would apply. How do you determine the operating temperature of a motor winding that does not have embedded detectors. The measured temperature value can be filtered with s300 and s700 from 5 18. Motor winding rtd temperature sensors are used to measure winding temperature of large motors generators etc.

Wire wound rtds embedded in stator slots are the most common method for measuring winding temperature in large motors. As you can see many common temperature sensors can serve as thermal winding protection devices for servo and induction motors. Interference of the signal can be eliminated with this function. The output temperature displayed is the hot winding temperature at the location of the sensor.

These sensor are sandwiched between the windings of motors generators.
