Description

The thermocouple temperature sensor has a simple structure, fast thermal response, convenient installation, wide temperature measurement range, and good stability. Output thermoelectric potential signal for temperature detection.    

The principle of using a thermocouple to measure temperature is that a thermocouple is composed of two different components of conductors connected at both ends to form a circuit. When the temperature of the junction is different, an electromotive force will be generated in the circuit, which is called the thermoelectric effect, and this electromotive force is called the thermal electromotive force. The generated thermoelectric potential varies with temperature, so the level of thermoelectric potential can represent the level of temperature. According to this principle, different types of thermocouples can be made.

Technical parameters

Model Example：WR-JMB1-206

Ordering Example：WR-JMB1-206/90-M12×1-900-M14×1.25-P2×1000

Installation method

When used for winding temperature measurement, a winding temperature thermocouple is selected. The thermocouple is installed inside the winding, and the lead wire is led out of the motor and connected to the motor's junction box. When used for bearing temperature measurement, bearing temperature thermocouples are selected. Drill holes in the bearing chamber according to the thread matching size, hinge the corresponding internal threads, and ensure reliable contact between the temperature measurement end face and the bearing. Do not let the sensor lead bear excessive tension, and pay attention to grounding the shielding wire.
