Siemens Pointek is an integrated short range ultrasonic level transmitter and dual switch for point level detection of bulk solids, liquids and slurries in the chemical, petrochemical, food, pharmaceutical, water and wastewater industries. Siemens Pointek capacitive level switches measure the level limit of liquids, solids, plastic granules, etc.

Pointek electronic capacitive level sensors do not contain mechanical components and are resistant to build-up and changes in the properties of the medium. This makes Pointek level sensors particularly reliable. Regular maintenance and cleaning is not required. The fully cast construction guarantees reliable performance of the capacitive level switch in vibration environments such as agitated tanks. Protective cap protects against wear, shock and abrasion in heavy duty applications.

What is a level switch?

Level control relays are designed to control and maintain a given level of conductive liquids and control electric motors of pumping units. The sensor controls the voltage value in the network and, when it goes beyond the established limits, disconnects the protected equipment from the power supply network.

The limit sensor is used to signal the overflow or emptying of tanks and containers with various geometric shapes and sizes with different liquids, as well as to signal the overflow or emptying of bunkers and silos with different bulk materials. The limit level sensor, when the required trigger point is reached, will close or open the relay, which will be connected to the mechanism that will turn off or turn on the supply of liquid or bulk substances to the tank. The output signal from the level control relay is a current relay, which can then be turned on to any light or sound signal.

Point level measurement of a product in a vessel, using the float level method, is one of the simplest methods for point level measurement of liquids. A metal float is placed at one end of the sensor rod, a magnet is installed at its other end, the movement of the float in the product causes the movement of the magnet, which through the hermetic wall of the sensor controls the reed relay output with position memory.

The main advantages of using the sensor is:

  • ease of use
  • lack of power
  • high reliability
  • the relay output of the device operates in the switching type mode
  • the level limit switch is used to monitor the level limit of various liquid substances.


Limit sensors differ according to the principle of operation:

  1. Float level switch is the simplest overfill alarm device. The most common application of this device is to protect the pump from dry running, as well as to control its operation (switching off when it reaches the upper level and turning it on when it reaches the upper position).
  2. Vibrating point level switch. The principle of operation of the sensor is based on a change in the medium in which the vibrating part of the fork oscillates, which causes a change in the connected mass of the oscillatory system, which in turn changes the natural resonant frequency of the oscillation. The emitter of the sensor generates vibrations, and the receiver of the sensor perceives them.
  3. Capacitive sensor. The principle of operation is based on the so-called capacitance change principle formed by the conductive wall or the reference probe and the measuring probe of the capacitor. The measurement product acts as the dielectric of the insulator in this capacitor. Depending on the level of the product, the capacitance of the capacitor will change.
  4. Conductive sensor. The operation of the level switch is based on the principle of the electrical conductivity of a liquid. To control the level, the electrodes of the signaling device are immersed in a container, which, together with its wall, if it is made of a conductive material or an additional reference electrode, are contacts in a common electrical circuit.
  5. Rotary limit switch. The level limit sensor is a blade that is mounted on the axis of the electric motor and placed in the hopper. When the electric motor is running, the blade is set in motion. The motor is located in the device body outside the bunker. When the hopper is filled and the controlled product approaches the rotating blade, it rests against the product and stops, the motor continues to work and sets the rotary support in motion. The microswitches located on the support monitor this movement, close and stop the motor. An additional microswitch controls the operation of the relay output.
  6. Vibrating point level switch. The presence of a microcontroller available in the signaling device allows you to control the change in the value of the resonant frequency of the oscillation and is responsible for the operation of the relay output, which can take on the values of a normally closed or normally open state of the relay, which allows it to be used in various conditions.
