The Goldammer NR 70 - TMA is a solenoid-operated level temperature regulator designed for tank inserts. It functions to monitor and regulate liquid levels and temperatures using bistable protective gas contacts housed within the switching tube.
For fixed contacts, intervals and functions must be specified during ordering. Plain contact cartridges allow subsequent height adjustment, with the make or break function altered by a 180° rotation of the cartridge. The device utilizes a permanent magnet built into float switches to trigger contacts upon level changes, featuring a hysteresis of 4 mm.
