Pepperl + Fuchs ultrasonic sensors


Ultrasonic sensors can determine current level of material in a given space or distance to object with using ultrasonic signal.

P&F ultrasonic sensors advantages

Sensors of this type are widely used in production today. The principle of operation is in a special pulse, which is sent from emitter with ultrasound speed in direction to the measured object. Further, signal contacts with its surface and is reflected. After that, the pulse enters into receiver. According to received data, device determines and displays the result.

The great popularity of such equipment is caused by its advantages. All measurements are contactless. Sensors of this type do not have physical contact with measured material, therefore they are not exposed to a high wear level.

Sensors have ability to determine object material type. That is, device is able to recognize whether it works with metal or plastic. Appliance also can detect wood, fluids and many more other materials.

In addition to lack of mechanical wear, such sensors are also resistant against natural influences. This greatly increases their service life.

Ultrasonic sensors P+F are successfully used in the following areas:

  •  oil;
  •  chemical;
  •  pharmaceutical;
  •  food;
  •  metallurgy;
  •  mechanical engineering, etc.

That is, the scope of such sensors application is very wide. In addition to determining level or distance, such equipment can perform some other tasks.
For example, it can operate in automated systems to prevent emergencies. Devices also determine objects passage through a certain point (for example, in conveyors).

Types of Pepperl and Fuchs ultrasonic level sensors

Despite the general operation principle, ultrasonic sensors are also divided into several categories.
Pepperl + Fuchs company produces the following types of ultrasonic sensors:

  •  diffuse;
  •  thru-beam;
  •  double sheet.

Diffuse ultrasonic sensors are the most popular one. This is because ultrasonic transducer serves as both emitter and receiver. A very important advantage is that such transducer is in one housing with an electronic converter. This design allows device to have a compact dimensions and at the same time perform several functions. There is also a simple opportunity to turn such sensors into reflective ones.

Through-beam ultrasonic sensors use a very powerful acoustic beam. This allows device to increase working range. Such sensors don’t need to constantly switch between the functions of emitter or receiver. This is possible because they do not wait to return of reflected signal. Sensors of this type have a very high response speed and switching frequency.

The last category is double-sheet sensors. This special type is very similar to the through-beam sensors. However, such devices are specifically designed to work with sheets of material. They can determine the overlap or intervals between batches. Sensors can also recognize the pasted label and differ it from the base material. Such equipment can work with metal, wood and even glass.

In addition to main sensor series, the company also produces special accessories for them. This includes various modifications of the fixing flanges, cables, mounting aids.
