DIGICONTROL- Gerätedatenblatt R-RAK www.gfr.de [ 82130 ] Category: Field Units - Monitor Universal thermostat DIGICONTROL R-RAK Application For controlling and monitoring the temperature of liquids in baths, containers, pipes and ducts. Because of its modular design and universal housing, the thermostat is very versatile. It can be used as: a stem-type thermostat with protective tube (pocket); a clamp-on thermostat on pipes; a thermostat with a remote sensor; or a double thermostat. Universal housing made of plastic; can be fitted in various ways; snap-on lid with window, sealable; internal setpoint adjuster; thermostat module with single-pole change-over contacts (TB has normally-closed contacts); capillary tube (which can be uncoiled according to needs, depending on the fitting method) and sensor cartridge; screw terminals for wire of max. 1,5 2 mm ; cable screw fitting for cable of up to Ø 9 mm.

The adjustable setpoint Xs equals the upper switching point. The switching difference Xsd is fixed. By dovetailing their housings together, two units can be linked to each other side by side, thereby easily allowing a double thermostat (controller-monitor or monitor-limiter) to be employed. On reaching the setpoint, the contacts change over and lock mechanically. Not until the temperature has fallen can the thermostat be reset by pressing the internal ‘Reset’ knob.
