Bang-bang control


In two-point control (also discrete or discontinuous control), there are two possible states, namely “on” and “off”.

Capacitive pressure sensor

A capacitive sensor is based on the principle that the electrical capacitance of a plate capacitor can be influenced in the following way

Data logging

Data logging

Data logging refers to the process of recording data and storing it on a storage medium.

Direct start star-delta startup

Savings potential by pump control with frequency converter Pump controls with direct start or star-delta start (depending on pump capacity) are suitable for automatic or manual control of three-phase pumps with functions individually tailored to your needs.


Float switches consist of a float that experiences buoyancy from the liquid to be measured and triggers a switching operation due to the buoyancy force.

Frequency converter

A frequency converter is a power converter that generates an output current variable in frequency and voltage from an alternating current in one or more phases.

Functionality PID

The PID controller uses three links, the P link (proportional component), the I link (integral component) and D link (differential component).


The hysteresis represents the range around the setpoint by which the actual value is allowed to fluctuate so that constant switching on and off of the control is prevented.

Level control

Level Control

The level control does not ensure a constant pressure, but a constant level.

Level probe

Level probes measure the hydrostatic pressure of the liquid column above them.

Multi-channel data logger

Multi-channel data loggers open up numerous application possibilities. They record the data from several measuring points at a central location and can store them.

Other temperature sensors

With the resistance-dependent temperature sensors, an external voltage must be applied in order to determine a value.

P controller

The 2-point control is realized via a P-controller. The output signal is proportional to the input signal, which illustrates the simplicity of the control.

PID control

PID control universal controller

PID control is used to adjust a controlled variable (e.g. pressure, temperature, frequency, etc.) to the setpoint. For pump control, these PID controllers are of great importance because they are an integrated component that controls the speed of the pump and thus enables automatic operation with all the resulting advantages.

Piezoelectric pressure sensor

This type of sensor uses the piezoelectric effect. When a piezoceramic material is deformed by pressure, an electrical voltage is formed across it due to charge displacement.
