Corund-M21 Spark Protection Passive Barrier for Sensor Applications

Barriers Korund-M21 are designed to work with sensors forming both natural output signal (e.g. thermocouples and resistance thermometers of standard graduations with conventional design) and unified current signal (e.g. 4-20mA) and other technical means of industrial automation, which do not contain their own power supply sources (e.g.

electropneumatic converters and positioners).
