The pressure sensor – a device, the physical parameters which vary depending on the pressure of the medium (liquid, gas, steam). The pressure sensors of the medium is converted to a standardized pneumatic, electric signals or a digital code.

Inductive sensor – contactless sensor for monitoring the position of a metal object (to other materials is not sensitive).

Inductive sensors are widely used for solving problems APCS. Performed with normally open or normally closed contact.

The principle of operation is based on changing magnetic field parameters generated by the inductor in the sensor.

Optical sensors – small-size electronic devices capable under the influence of electromagnetic radiation in the visible, infrared and ultraviolet ranges apply a single or plurality of signals to the input or the recording of the control system. Optical sensors responsive to opaque or translucent objects, steam, smoke, aerosols.

Optical sensors are a type of contactless sensor, as a mechanical contact between the sensitive area of ​​the sensor (sensor), and acting object is absent. This property of the optical sensors causes their wide application in automatic control systems. The range of the optical sensor is much larger than that of other types of proximity sensors.

Optical sensors are also called optical proximity switches, photo sensors, photoelectric sensors.

Laser diffuse reflection sensor for direct detection. The emitter and receiver are in a single housing. The emitter emits a thin laser beam which is reflected from the object detection. A thin laser beam makes it possible to detect even very small objects and their position.
In case laser light barrier reflected light transmitter module and receiver module are in the same housing. The transmitter emits a thin laser beam which, with the specially developed for the prismatic reflector laser sensors, returns to the receiving module. Processed interrupts the laser beam. Due to the small diameter of the laser beam can detect small objects and, accordingly, to position them accurately.
