Control engineering – Measurement and control solutions for industrial processes

Control technology covers all measures used to keep a process variable such as temperature, pressure, level or flow at a defined setpoint. Sensors measure the actual value, a controller compares it with the setpoint and adjusts heaters, valves or motors accordingly. You need control technology wherever processes must run in a stable, reproducible and safe way.

In the control technology category you will find temperature controllers, universal and PID process controllers, display and control units, telemetry modules for remote monitoring as well as RS-485/MODBUS components. In addition, we offer time relays, limit switches and protection relays that monitor and safeguard your control loops.

A temperature controller is dedicated to temperature control and provides suitable sensor inputs such as Pt100, Pt1000 or thermocouples. A process controller is more universal and can handle various standard signals, for example 0/4–20 mA or 0–10 V, allowing it to control pressure, flow or level as well. Many modern process controllers use PID control and can be configured for a wide range of industrial applications.

Our control technology products are used in industrial automation, machinery and plant engineering, HVAC systems, energy and power management systems as well as laboratory and test environments. Typical applications include temperature control in ovens, monitoring of pumps and motors, protection of equipment using voltage monitoring relays and remote monitoring via telemetry modules.

Key parameters are the variable to be controlled (e.g. temperature or pressure), the sensor type or input signal, the number of inputs and outputs, the required control performance (on/off or PID) and the interface you need, such as RS-485/MODBUS. If you are unsure, simply provide us with the basic data of your application and we will recommend suitable temperature controllers or process controllers.

Many of our display and control units, process controllers and telemetry modules are equipped with an RS-485 interface and support the widely used MODBUS RTU protocol. This makes it easy to integrate control loops into existing SCADA systems, PLCs or supervisory control systems and to collect and log measurement data centrally.

Yes, most of our controllers, telemetry modules and protection relays are designed for DIN-rail mounting and can be integrated into existing switchboards. You only need to check the electrical ratings, supply voltage and interfaces. If you have questions about retrofitting, we will be happy to help you with concrete suggestions for suitable controllers and modules.

If required, we support you in selecting and configuring controllers, telemetry devices and RS-485/MODBUS components. Many devices provide clear menu structures or PC software for easy parameterization. If you have specific requirements for your process control system, we will discuss them in advance and recommend an appropriate combination of transmitters, process controllers and communication modules.
