industrial sensor

1.Industrial sensor product principle

industrial sensor is a kind of equipment in industrial automation, which can detect the change of quantity and convert it into an output signal, including pressure sensor, infrared sensor, smoke sensor, optical sensor and so on.The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and is received again by the antenna system. The signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the microwave propagates extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time taken is almost instantaneous).

3. Industrial sensor product features

The antenna is small in size and easy to install; the non-contact radar has no wear and pollution.

Almost unaffected by corrosion and foam; almost unaffected by water vapor, temperature and pressure changes in the atmosphere.

Serious dust environment has little impact on the operation of high-frequency level meters.

The wavelength is shorter and reflects better on tilted solid surfaces.

The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.

The measurement blind area is smaller, and good results can be achieved for small tank measurements.

High signal-to-noise ratio for better performance even under fluctuating conditions.

High frequency, it is the best choice for measuring solids and low dielectric constant media.
