The gas density monitor TS consists of the following principal components:
- Aluminum housing and pressure connector
- Electronic PCB with up to five microswitches
- Reference gas bellow, filled with SF6 gas
The density monitor TS monitors gas density by way of a reference chamber filled with SF6 gas. The gas and reference chambers are separated by a metal bellows. A density and pressure difference between the two chambers deflects the metal bellows. The movement of the bellows is transmitted by a switch rod. A switch plate activates the microswitches whose purpose is to indicate a pressure drop.
The operating points for triggering the signal can be set at the factory according to the customer’s requirements by way of lockable screws (plungers). Up to five microswitches with changeover contacts can be installed in the housing. The microswitch contact outputs are taken to terminal tabs on the PCB. The use of vibration-resistant microswitches rules out any shock-induced chattering at the switching contacts.
