Instrumentation and control (I&C)


Physical or chemical quantities are determined by measuring. Sensors detect the data and transmit these to a measuring transducer that transforms the data to a corresponding signal or display value. The combination of sensor and measuring transducer is generally designated as a measuring device.

Measuring devices are used to measure

  • Pressure, temperature, flow rate
  • pH value, redox potential
  • Ozone concentration in the process air and in the water
  • Pollutants in the air
  • Conductivity measurement, ion measurement
  • etc.

Selection of the right measuring instruments is of great importance. Do not hesitate to ask us - we will be pleased to give you the right recommendation for every application.


Control systems can be used to define specific sequences in accordance with a defined pattern or plan. A typical example of this id a pump control system. Through a start command (e.g. Tank empty) a circuit is activated which starts up the pump and lets it pump until a specific volume has been pumped or a specific level has been reached.
During operation important operating states (motor temperature, mass flow, initial pressure, etc.) are detected and also evaluated.

Reliable control systems contain a high protection and monitoring level.

Closed-loop controlling

Closed-loop controls keep specific specified operating data at a constant level. Examples of closed-loop controls are:

  • Temperature control
  • Pressure control
  • Flow rate and quantity control
  • Level control
  • Controlling of chemical data such as ozone concentrations

In addition to the theoretical knowledge closed-loop control tasks also require great practical experience, both in selecting the measuring technology and for the selection of the right control elements. Rely on our experience.
