All about
bayonet probes
RTD bayonet sensors, thermistors or thermocouple probes are commonly used to measure the temperature of motor bearings.
These temperature indicators are primarily designed for making measurements from solid substances. Nevertheless, it is still possible to use them for liquids or gases.
The bayonet nut screwed on a spring allows the sensor to be mounted on the measuring point. The spring then ensures optimal contact with the area to be measured.
Furthermore, the combination nut, spring and bayonet connector is also very useful to compensate for a change in the distance between the nut and the measuring point.
The bayonet probe is used to measure the temperature of the motor bearings.
The bayonet cap and the spring ensure high operational reliability in the temperature reading. Indeed, the mechanical vibrations, the expansions as well as the contact pressure guarantee a good thermal coupling.
And for more precision, it is possible to rotate the bayonet cap on the spring. You can then adjust the immersion depth according to your needs.
Guilcor offers several models of bayonet temperature sensors. Depending on the type of probe chosen, here are the characteristics that you will find for each measurement system:
- Case: stainless steel
- Diameter: choice,
- Case length: 10 to 200 mm
- Variation of connection cable: PVC, shielded or not, silicon, Teflon, fiberglass
- Degrees of protection: IP 50 to IP 67 according to standard EN 60529
- Temperature range (depending on cable variation): -30 to 80°C; -40 to 105°C; -50 to 250°C; 0 to 400°C
- Material: nickel-plated brass, stainless steel
- Resistance: 200 MΩ at 500 V DC; 25 ± 3 degrees Celsius
- Maximum allowable static traction: 1kg
- Accessories: thermowell, bayonet adapter, connectors
The probes are designed to operate in a non-aggressive environment.
You will then have to select your measuring device according to the contact temperature, the resistance, and the cable.
At Guilcor, you will find several bayonet probes for temperature control. Do not hesitate to contact us to select the sensor you need. We guarantee fast delivery to over a hundred countries.
In addition to offering you the bayonet measurement probes shown on this page, Guilcor also allows you to design your own equipment according to your needs. For example, you can choose the dimensions of the case (in terms of diameter and length), the materials used and the end of the case.
