Wire wound rtds embedded in stator slots are the most common method for measuring winding temperature in large motors.
Motor winding temperature sensor.
Motor winding rtd temperature sensors are used to measure winding temperature of large motors generators etc.
Normally six sensors are recommended for each motor two per phase.
Pt100 ω rtds measure the lift station pump and motor bearing temperatures and the motor winding temperatures are measured by cu10 ω rtds.
The measured temperature value can be filtered with s300 and s700 from 5 18.
Each lift station can have a number of temperature sensors which are monitored by the station operator.
If a handheld temperature detector were to read 129 c as in the example above the same concerns about the overall temperature would apply.
Interference of the signal can be eliminated with this function.
As you can see many common temperature sensors can serve as thermal winding protection devices for servo and induction motors.
The output temperature displayed is the hot winding temperature at the location of the sensor.
The measured and filtered temperature value is used for supervising and for monitoring the motor temperature.
Unlike on off devices it allows continuous measurement of winding temperature.
The stator winding temperature detector rtd are used to measure winding temperature of large motors generators etc.
These motor temperature sensors are sandwiched between the windings of motors generators.
Thermal winding protection and keb vfds.
Flexible and stable monitoring with the option of easy and quick configuration.
The wire wound element extends through most of the body length and measures the average temperature of the winding.
How do you determine the operating temperature of a motor winding that does not have embedded detectors.
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.
Ptc thermistors motor sensor is ceramic ptc thermistor pellet with insulated wire cable used for motor temperature sensing and over temperature protection by using ptc thermistor characteristics resistance rises sharply at curie temperature.
Thin film rtds are identical except for the size of the sensing element.
The time constant of the filter can be set with tempmfilt.
