Process indicators & control units
Our product finder helps you to search for suitable measuring devices, software or system components via product characteristics. Applicator leads you through an individual product selection via application parameters.
Analog measured values are indicated, evaluated and calculated by process indicators. Large displays offer easily readability at all ambient conditions. The universal inputs enable the connection of current, voltage, RTDs and TCs. Loop powered indicators require no power supply and can be universally used in current measuring circuits. They can be easily installed in intrinsically safe applications. Fieldbus indicators support all bus devices and indicate the values communicated on the bus.
Portfolio description
Our portfolio of process indicators & control units provides:
Process indicators for panel mounting as well as for field mounting
Loop powered process indicators for direct installation in Ex-areas
Process indicators with HART display for up to 4 values in one device
Process indicators with control function (limit value monitoring, mathematics, differential pressure and linearization,...)
Fieldbus indicators for integration into fieldbus systems
These indicators require no power supply and can be universally used in 4 to 20 mA current measuring circuits. They can be easily installed in intrinsically safe applications. They are used where measurement values have to be clearly visible or where the display of the measuring device is hard to read due to the installation conditions. They are very convincing because of their high contrast display of process values under all environmental conditions.
Measuring principle: Fieldbus indicators
These indicators support all bus devices and indicate the values communicated on the bus.
The PROFIBUS® PA version of the devices acts as a pure listener without an own device address.
The FOUNDATION Fieldbus™ indicators can be operated either in a Listener Mode or in the standard mode using a function block connection.
Measuring principle: Indicators with control function
Indicators with control function combine several functionalities in one device:
Active barrier
Transmitter
Control unit with relay
These features combined with the brilliant displays offer highest comfort and best functionality on site.
