Piezoresistive pressure sensor
This type of sensor uses the piezoelectric effect. If a piezoceramic material is deformed by pressure, an electrical voltage is generated above it due to charge displacement. (more…)

This type of sensor uses the piezoelectric effect. If a piezoceramic material is deformed by pressure, an electrical voltage is generated above it due to charge displacement. (more…)
The pressure control has the task of maintaining a certain setpoint pressure. This is achieved, for example, by an automatic pump control with a connected pressure sensor. (more…)
The actual pressure must be measured with a pressure sensor in order to regulate the pressure to a specific target pressure.
Radar sensors are mainly used for distance measurement over longer distances and for speed measurement. (more…)
Remote alarming is part of remote monitoring. For this purpose, sensors determine specific measured values continuously or discontinuously. (more…)
The remote control of systems describes the regulation and control of a system from outside. (more…)
Remote maintenance is the administration of systems from remote locations for the purpose of maintenance. This principle has several advantages:
Remote monitoring is a central element of many pump control systems. It makes it possible to centralize monitoring and, if necessary, control. (more…)
The most common method for determining the temperature is to measure temperature-dependent resistances. (more…)
For data logging of special measured values, it is possible to combine the data logger and the corresponding sensor in one device. (more…)
A soft starter is used for the soft start of an electric motor. In principle, this is a phase angle control, which is realized through the use of thyristors. During start-up, the voltage is reduced on average, which leads to significantly lower current peaks than with a direct start, for example.
However, a soft starter is not suitable for operating a motor at a lower frequency than the mains frequency.
This requires a frequency inverter.
Star-delta starting describes the control of electric motors. There is a circuit with contactors through which a motor is initially star-connected when it is switched on. After a certain time, usually realized by time relays, the motor is switched from star to delta connection. This control reduces the starting current and the starting torque. As with a direct start, current peaks do occur. However, these are lower.
A soft starter or frequency inverter can be used to control a motor instead.
The submersible motor pump is a multistage axial high-performance centrifugal pump that is installed vertically.

Temperature control is used in various applications, for example in chemical processes, but also for storing temperature-sensitive fillers. (more…)
Temperature measurement is the basis for precise temperature control. In the technical environment, it is always carried out electrically or electronically. (more…)
