Bulk solids · Level switch

Rotary Motorized Level Switch

Rotary (rotating paddle) motorized level switches are used to detect when bulk solids reach a set level in silos, bins, hoppers and similar storage. A paddle driven by a low-speed motor is stopped when the material covers it; the motor torque protection then trips and the contact output changes state. When the material falls away, the paddle starts turning again and the output returns to its original state.

Thanks to the adjustable shaft length and different paddle geometries, it can be used with materials of different densities such as flour, feed, grain, sand, cement and plastic granules. It is positioned as a high-level (full) or low-level (empty) alarm.

Key features

Mechanical detection with a rotating paddle – works regardless of material type
Motor protection: the motor stops automatically when blocked, reducing energy use

Powders · Continuous level

Infrared Level Sensor

An infrared level sensor developed for the proportional measurement of granular solids and powders. Designed for solids filling systems, it detects the product accumulating in the tank it is mounted on, not the product flowing past.

With no moving parts there is no wear and no maintenance; it is not affected by dust build-up, vibration or pressure. Its 4-20 mA analog output connects directly to a PLC, panel meter or SCADA system.

Key features

No moving parts – no maintenance or cleaning required
Unaffected by dust build-up and vibration
Pressure-resistant housing
Easy, one-time installation
4-20 mA proportional output

Technical specifications

Supply	24 V DC
Output	4-20 mA analog
Measuring principle	Infrared (IR) reflection
Application	Solids filling / powder tanks

Applications

Roller millsPowder filling machinesTanks with granular solidsFlour, starch and powdered chemical lines

Liquids & solids · Continuous level

Capacitive Continuous Level Sensor

Capacitive continuous level sensors continuously measure the change in capacitance between the measuring probe and the tank wall (or a reference electrode) and convert it into an analog signal proportional to the level. They can be used with liquids, sticky and viscous products, powders and granules.

Probe length, material and coating are selected for the application; calibration against temperature and dielectric changes can be done on site. Microcontroller-based signal processing suppresses the effects of build-up, foam and condensation in software.

Key features

Continuous (proportional) measurement – as fill percentage or in mm
Suitable for liquids, viscous media, powders and granules
On-site empty/full calibration
Rod or cable probe, manufactured to the required length
4-20 mA / 0-10 V / RS485 Modbus output options
Build-up and foam compensation

Technical specifications

Supply	12–24 V DC
Output	4-20 mA · 0-10 V · RS485 (optional)
Probe	Stainless steel, PTFE/PE coating option
Probe length	Per application
Operating temperature	-20 … +85 °C (electronics)

Applications

Water and chemical storage tanksViscous products such as oil, milk and syrupPowder and granule silosWastewater and treatment

Liquids & solids · Point level

Capacitive Level Switch

Capacitive level switches provide a digital (on/off) output by detecting the change in capacitance that occurs when the probe comes into contact with the material. With no moving parts there is no risk of jamming, wear or breakage, making them a strong alternative to mechanical switches for sticky and bridging materials.

With its sensitivity adjustment it works across a wide range, from low-dielectric powders to conductive liquids. It is used for high/low level alarms, pump protection and filling automation.

Key features

No moving parts – maintenance-free
Adjustable sensitivity and delay time
Selectable NO/NC relay or PNP/NPN transistor output
Reliable detection in sticky and bridging materials
Short probe or extended shaft options

Technical specifications

Supply	24 V DC / 220 V AC (depending on model)
Output	Relay 5 A NO/NC or PNP/NPN
Sensitivity	Adjustable via potentiometer
Delay	0–10 s adjustable
Operating temperature	-20 … +80 °C

Applications

Liquid tanks – overflow and dry-run protectionPowder and granule hoppersFilling machinesFood and chemical process lines

Line Following Sensor

Line following sensors measure the vehicle's deviation from its path by tracking a coloured/contrast tape applied to the floor or an energised wire embedded in it. Thanks to the multi-channel design, the output is not just "line / no line" but the proportional position of the line under the sensor (amount of left/right deviation); the drive controller uses this to correct the steering.

The optical version works on contrast tape and includes ambient light compensation. The inductive (wire guidance) version detects the magnetic field generated by a conductor under the floor and is unaffected by dirt, wear and wet floors. Both types connect to the robot controller via UART / RS485 / analog output.

Key features

Multi-channel detection – proportional deviation data
Optical (contrast tape) and inductive (embedded wire) options
Ambient light and floor reflection compensation
UART / RS485 / analog output, digital junction markers
Low-profile housing suitable for under-vehicle mounting
Suitable for in-plant AGVs, warehouse robots and educational robots

Technical specifications

Supply	5 V / 12–24 V DC (depending on model)
Output	UART, RS485, analog deviation signal
Sensing height	Optical: 5–30 mm · Inductive: 20–80 mm
Channels	8 / 16
Operating temperature	-10 … +60 °C

Applications

AGVs and autonomous transport vehiclesWarehouse and in-plant mobile robotsAgricultural mobile platformsRobotics training kits
