Check whether the PT100 type sensor works satisfactory.
The PT100 sensor can be divided into 2 wires, 3 wires and 4 wires mode according to different application scenarios (as shown below). In this paper, a 3-wire PT100 sensor will be used to describe the checking procedure.

Electric motor products are widely used power equipment. According to the different application conditions of the motor, they are divided into different series of products, such as motors specially used in lifting metallurgy, textile, roller and other occasions with tendency requirements. According to the personalized requirements of the application conditions, the design and performance of the motor will tend to meet the requirements.

Inverter motors are motors that use inverter technology to control the speed of the motor. Inverter technology uses electronic equipment to control the speed of the motor, thus realizing the control of the motor's speed, power and efficiency.

Explosion-proof motors, as the main power equipment, are usually used to drive pumps, fans, compressors and other transmission machinery. Explosion-proof motor is the most basic type of explosion-proof motor, because of its shell non-sealed structure characteristics, the main flammable gas gas in the coal mine to reach a certain concentration limit.

Explosion-proof motors need to do a series of preparatory work before use, in order to ensure that explosion-proof motors in operation can maintain the normal state, this step is very critical, then we need to do those jobs before use?

Generation of magnetic fields
The first thing that is talked about is the generation of the magnetic field. In a high voltage motor, the magnetic field generated by current flowing through the windings interacts with the magnetic field generated by the permanent magnets or the applied current to form a torque that drives the motor to rotate. The essence of this interaction is the mutual attraction or repulsion between the magnetic field lines of force.

The coil insulation of high voltage motor has a great impact on the service life and economic effect of the motor, which is a problem that every designer and technician must carefully consider. The high-voltage coil can be called the heart of the motor to some extent, which directly determines the service life of the motor, and the performance of the insulating material, which is an important component of the coil, is crucial.

AC (alternating current) and DC (direct current) motors are two common types of electric motors used in various applications. While both types of motors serve the same purpose of converting electrical energy into mechanical energy, they operate on different principles and have distinct characteristics.

AC motors are one of the most widely used motors in industry and agriculture, with capacities ranging from tens of watts to kilowatts, and are widely used in various industries in the national economy. 

In industry: small and medium-sized steel rolling equipment, various metal cutting machine tools, light industrial machinery, mine hoists and ventilators are all driven by asynchronous motors. 

High-voltage motor cooling methods is a key factor in ensuring the efficient operation and longevity of these powerful machines. High voltage motors are typically used in industrial environments and are subject to heavy workloads and extreme conditions.
