The high temp proximity sensor refers to a proximity switch that can work at high temperatures. The switch that uses the sensitive characteristic of the displacement sensor to approach the object to achieve the purpose of controlling the switch on or off is called the proximity switch.

The high temp proximity sensor is used for detection, positioning, counting, etc. in high temperature and harsh environments. High temperature resistant proximity sensors can operate in high temperature environments for a long time and are now widely used in high temperature automation control fields such as steel, metallurgy, and casting. Through special customized cables and high-temperature-resistant chips.

The vibrating coil of the high temp proximity sensor generates an alternating electromagnetic field. Any conductive material entering the magnetic field will absorb energy from the oscillating circuit and generate eddy currents. Then the attenuation of the oscillator is converted into a switching signal in the output amplifier.

Based on this functional principle, all metals can be detected, whether they are moving or not. Because the high-frequency magnetic field is not affected by the temperature and the magnetism inside the detected object, the high-temperature induction switch is not affected by the operating environment of the sensor.

The high temp proximity sensor is a set of components and other housing plate sensors. The housing is usually connected to the ground or the equipment terminal during the measurement.

When an object is close to the sensor, whether it is a conductor or not, because it is close, the change in the dielectric constant of the total capacitance causes the change of the capacitor, and the state of the measuring head connected to the circuit is correspondingly changed, thereby controlling the sensor to open or close.

It uses a conductive object to approach, which can generate an electromagnetic field close to the sensor, which will create an eddy current inside the object. The eddy current response is close to the sensor, the sensor’s circuit parameters change, so as to find the presence of a conductive object, and then control the sensor to turn on or off. In this way, the sensor can detect the conductivity of the object.

The main difference with ordinary capacitive proximity sensors is that we have a wide operating temperature range, which can withstand a maximum temperature of 120°C and a minimum temperature of minus 25 degrees. The detection of substances in extreme environments can meet the special needs of chemical fiber, food, and other industries.

The high temp proximity sensor has a wide voltage range, high repeat positioning accuracy, fast frequency response, anti-interference performance, high temperature resistance, good waterproof performance, easy installation and debugging, and long service life.
