초음파센서란

Presence detection

Sensors with a switched output, e.g., from the mic+ sensor family can be used, depending on the size of the box or container. The mic+25/D/TC, mic+35/D/TC or mic+130/D/TC can be selected for scanning small boxes.

With larger containers you are recommended to use a mic+340/D/TC or mic+600/D/TC. If the box or container is to be scanned by several sensors, it is recommended to synchronise them with each other.

Furthermore, the pms ultrasonic sensor in hygienic design is recommended in the food industry, the pharmaceutical industry or the beverage industry.

Path edge control

The ultrasonic edge sensors bks are designed as fork sensors and function as a one-way barrier. They are used for path control and emit an analogue signal of 0–10 V or 4–20 mA which is proportional to the orientation of the path edge.

Double sheet control

identifies two or more sheets of material on top of each other. The  dbk+4 product range is ideal for use where paper is in use, such as sheet fed printing presses, printers, copiers or collating machines. For thicker materials, plastic sheets and coarse corrugated cardboard, the dbk+5 ultrasonic double-sheet detection is used.

Checking diameter

The diameter of a roll or coil of material can be detected by an ultrasonic sensor with analogue output and the drive adjusted or brake applied accordingly. For small diameters this is a typical application for a mic+35/IU/TC and for diameters up to 2.5 m a mic+130/IU/TC.

Installation for a foil extruder

The mic+ ultrasonic sensors with analogue output 0 – 10 V and 4 – 20 mA are ideally suited for controlling the diameter on a foil extruder.

Through-beam barrier

Ultrasonic through-beam barriers are highly suited for reliable presence control and counting of objects at high speed. The through-beam barrier consist of a transmitter and a receiver. The transmitter emits acoustic pulses on a cyclical basis which are captured by the receiver. If an object interrupts the pulses between the transmitter and the receiver, the switching output of the receiver is set.

The robust ultrasonic barrier ews is available as a cuboid miniature housing and a cylindrical M18 housing.

Label detection

The esf-1 label sensor reliably detects high-transparency, reflective materials as well as metallised labels and labels of any colour. The measurement cycle time automatically self-adjusts to the sound power required.

Foil tear monitoring

Can be implemented with all ultrasonic sensors with switching output. If the material does not lie flat, it is advisable to operate the sensor as a two-way or reflective barrier. This operating mode also works reliably when the sonic beam is deflected away by the waves in the material. All ultrasonic proximity switches with the microsonic Teach-in support the operating mode reflective barrier.

Filling level monitoring in small containers

Detection of filling levels from just a few millimetres up to 8 m can be made. Ultrasonic sensors with one or two switched outputs for minimum/maximum control, or with 0-10 V and 4-20 mA analogue output are available. Even in small containers with a diameter of less than 5 mm can be measured with the zws ultrasonic sensor + SoundPipe.

Detecting obstacles

Ultrasonic sensors of the mic+ family enable the contactless protection of automated guided vehicles in the driving direction. When using several sensors these can be synchronised with each other to avoid influencing each other. With a pre-alarm range and a stopping range, the vehicle can be halted smoothly before an obstacle without the impact bumper triggering the braking mechanism.

Height control of the field sprayer boom

For height control of the field sprayer boom, several wms ultrasonic sensors or mic ultrasonic sensors continuously measure the distance to the crop. The control system of the field sprayer uses the measured distance values to compensate for unevenness in the soil and different plant heights. This allows crop protection agents or fertilisers to be distributed evenly over the field.

The all-metal housing of the two sensor families is specially designed for outdoor applications on agricultural machines.

Height and distance detection of rows of trees or trellises

The wms ultrasonic sensors or mic ultrasonic sensors measure the lateral distance to vines or trellises. With the measured distance values, the control system automatically adjusts the line of the harvesting platform.

The continuous height detection of the rows of trees or trellises allows the spraying areas to be identified. Thus, spraying areas can be added or removed automatically via the control system. This minimises the use of crop protection agents and ensures even distribution.

높이 및 폭 측정 (Height and width measurements)

Edge detection of flat objects

Very flat objects on a conveyor belt can often be detected via an "indirect" reliable measurements: An ultrasonic sensor with switching output measures the edge of the object in an incline compared to the conveyor transport direction. The edge of the object forms a triple reflector with the conveyor belt and reflects the sound waves back to the sensor.

Splice detection

The esp-4 splice sensor reliably detects splices and also labels. It is available both in M18 housings, as well as in M12 with external receiving transducer.

Wire break detection

during the winding/unwinding of wires. Depending on the size of the drum, a mic+130/D/TC with 1,300 mm operating range or a mic+35/D/TC with 350 mm operating range can be used. If the position of the wire on the drum should be recorded, there are ultrasonic sensors with analogue output available.

Stacking height control

Whether wooden boards, panes of glass, sheets of paper or coloured plastic panels, ultrasonic sensors are ideal for detecting the height accuracy to millimetre precision.

Monitoring of trays

초음파 센서는 초음파가 물체에 흡수되거나 모서리 검출 또는 초음파 감지가 먼 경우가 있기 때문에 항상 양방향이나 반사판을 사용하여 설치되어야 합니다. 이 상황에서 추가적인 반사판은 검출할 물체의 뒤편에 설치됩니다. 초음파 센서의 스위치 출력은 창mode(모드, 방식)에서 물체감지를 하고 반사되는 초음파 신호로 검출합니다. The lpc+ in the M18 threaded housing is ideal for this purpose.

Ultrasonic barrier

It is easy to set up a two-way or reflective barrier using an ultrasonic sensor operating in window mode. To do this, a permanent reflector is positioned behind the objects to be scanned. When an object obscures the reflector, a switching signal is generated.

Sonic reflector

The sonic beam can be redirected via a reverberant, smooth reflecting surface. There are 90° sonic reflectors available as accessories for this. These can be used to advantage in certain confined installations.

Vibration feeder

Ultrasonic sensors, such as the pms sensor in Hygienic Design, continuously measure the level in the vibratory feeder. If the sensor detects a level that is too low, the feed rate is increased. Conversely, if the sensor detects a level that is too high, the control system reduces the product feed to ensure a consistent process.

Volumen flow

ultrasonic sensors can be used for continuously detecting the filling level of objects on a conveyor belt. When the sensor detects minimum filling level, the feed rate will be increased. On the contrary, when the sensor detects a maximum filling level, the control unit will reduce the feed rate in order to provide a smooth filling level process. The pms ultrasonic sensor in hygienic design is suitable for this process.
