Bang-bang control
In two-point control (also discrete or discontinuous control), there are two possible states, namely “on” and “off”.
Glossary Group: Controls
Functionality PID
The PID controller uses three links, the P link (proportional component), the I link (integral component) and D link (differential component).
Hysteresis
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.
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 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.
Pressure control
The pressure control has the task of maintaining a certain setpoint at the pressure. This is achieved, for example, by an automatic pump control with connected pressure sensor.
Resistance measurement
The most common method of determining temperature is by measuring temperature-dependent resistances.
Temperature control
Temperature control is used in various applications, for example in chemical processes, but also for storing temperature-sensitive fillers.
Temperature measurement
Temperature measurement is the basis for precise temperature control. In the technical environment, it is always carried out electrically or electronically.
Universal controller
The PID controller is also referred to as a universal controller because of its wide range of applications and differentiated mode of operation.
