Dial pressure gauge ILS - 53

G 1/2glassbrass

This designation designs all switch devices which close or open one or several circuits with regard to the needle position of pressure gauge. -The detectors ILS are composed of 2 flexible contacts sealed in a glass tube filled with neutral gas. When the magnet, driven by the pressure gauge needle is situated near the ILS detector, the two flexible contacts stick together and close the circuit. They are normally closure type : - Close detector at pressure reduction : function 1. - Close detector at pressure build-up : function 2. Cutoff capacity : 3 W or 3 VA. Maximum intensity : 0,25 A (for U = 12 V). Maximum voltage : 50 V (for I = 20 mA)(values given on resistive circuits). Electric connection : plastic connector DIN 43650 / Staffing box PG9. THIS TYPE OF CONNECTORS REPLACES FAVOURABLY DRY ELECTRIC CONTACTS FOR : AUTOMATE CONTROL : no bounce effect at setting point, there are no micro cutoffs . COMMUTATION IN SHOCK ABSORBING LIQUID : the cut-off capacity is higher than when using dry electric contacts and utilization of glycerine and sidepaline as shock absorbing liquid is possible.
