Watt thermistor

1、 Basic concepts

Watt thermistorThe end face thermistor WZPM2-001 is a type of thermistor specifically designed for measuring the temperature of bearing shells. It closely adheres to the surface of the bearing shell through temperature sensing elements (such as specially treated resistance wires), converts temperature changes into resistance value changes, and then measures the real-time temperature of the bearing shell.

2、 Working principle

The working principle is based on the characteristic of the resistance value of a conductor or semiconductor changing with temperature. When the temperature of the bearing increases, the resistance value of the temperature sensing element also increases. By measuring the change in this resistance value, the temperature of the bearing can be calculated. This temperature measurement method has the characteristics of high measurement accuracy and stable performance.

3、 Main features

High measurement accuracy: Usually made of high-purity metal materials such as platinum, copper, etc., these materials have a stable temperature coefficient of resistance, which can ensure the accuracy of measurement results.

Stable performance: It has good stability and reliability, and can operate stably for a long time in harsh working environments.

Fast response speed: Due to the temperature sensing element being closely attached to the surface of the bearing, it can quickly respond to changes in the bearing temperature and provide real-time temperature data.

Easy installation: The installation is relatively simple, just ensure that the temperature sensing element is in close contact with the surface of the bearing shell.

4、 Precautions for use

Stable power connection: When in use, it is necessary to ensure a stable power connection to avoid measurement accuracy being affected by power fluctuations.

Regular calibration: In order to maintain measurement accuracy, regular calibration is required.

Reasonable installation: During installation, it is necessary to choose a suitable installation position and depth to ensure that the temperature sensing element can accurately reflect the temperature of the bearing shell.

Maintenance and upkeep: Regular maintenance and upkeep should be carried out, such as cleaning the surface of the temperature sensing element, checking the connecting wires, etc., to ensure its normal operation.

5、 Application Fields

Watt thermistorWidely used in various occasions that require measuring the temperature of bearing shells, such as monitoring the temperature of bearing shells in mechanical equipment such as steam turbines, generators, and compressors. By monitoring the temperature of the bearing in real-time, potential equipment malfunctions can be detected in a timely manner, ensuring the safe and stable operation of the equipment.
