All about
winding probes
These are wired temperature sensors protected by an epoxy resin and a heat-shrinkable tube.
These sensors are distinguished by their high electrical resistance. Their dielectric strength is generally 2.5kV, allowing installation in most motors on the market. They are also compatible with all engine classes up to class H (180°C).
The winding and winding probe has many advantages:
- ergonomics thanks to its small size
- low thermal inertia
- advantageous cost
- reliability
- vibration resistance
Winding and winding probes are used in electronics and electrical engineering.
Their most common application is the measurement of temperature in the windings of electric motors and transformer windings. They can also be used for protection against winding overloads, monitoring and limiting temperature regulation in measurement techniques or controlling the temperature of power semiconductors, bearings of rotating machines, etc.
In addition to the products on this page, Guilcor also offers the production of specific products according to your needs (three-phase, asynchronous, single-phase, synchronous motor, etc.)
For three-phase motors, here are some recommendations:
It is preferable to implant the leads before winding. Moreover, we advise you to leave a space in the middle of the winding head in order to deposit the temperature sensor.
Each winding must be equipped with a probe, to be placed at the level of the hottest point (generally opposite the fan). As such, good thermal contact between the two is required. To do this, do not hesitate to squeeze the winding wires.
Connect the connecting wires to the free terminals.
There must be parallelism between the conductors of the probe and the wires of the winding
In the event of overheating, the motor will be disconnected from the mains. It will be connected to it again when it cools down.
Good to know: For test procedures, the measurement voltage must not exceed 2,5V direct current. Beyond that, there is a risk of overheating the sensor.
For professionals in the sector, it is essential to check the correct operation of the engine. For this purpose, Guilcor offers several winding and winding probes.
You can then choose your sensor according to your needs (single, double or triple, cable length, temperature range, etc.).
