Density Controller for SF6 and other Gases
Type: TS for indoor use

The Density Controller TS is a device just for control
purposes. The controller uses a chamber filled with an identical gas as a reference. When the reference chamber and the switching enclosure are at the same temperature, a change in density in the latter will induce a pressure differential. The switching enclosure and the reference chamber are separated one from another by a metal bellows. A differential in pressure will cause a deformation of the bellow. This deflection motion is transferred via a switching rod with a switching plate to actuate the microswitch required for signaling purposes. The switching thresholds can be adjusted by way of lockable screws at the switching cam.		 Density Controller for SF6 and other Gases COMDEDensity Controller for SF6 and other Gases COMDE Topview

Up to four microswitches with double-throw contacts can be installed in the type TS. The contact output for the microswitches terminat in aprobriate plugs DIN 46244: 6,3 x 0,8 mm. The microswitch response points are calibrated to the specified values.
The arrangement of the measurement mechanism and the use of vibration-resistant microswitches eliminate any shock-induced chattering at the switching contacts.
