DRY ELECTRIC CONTACTS – 15	-Contacts with slow action : warrant high adjusting accuracy with reduced hysteresis.  Contacts with sudden action (magnetic) : permit to reduce creation of electric arcs due to ill-timed switch-on of contact.  They are normally closure type : - Close contact at pressure reduction : function 1. - Close contact at pressure build-up : function 2.  The capacity of cutoff varies from 18 VA to 50 VA (on resistive circuits).  Use of time delay relay MSR is obligatory for control pressure gauges with shock absorbing liquid.  Electric connection : plastic connector DIN 43650 / Staffing box PG9. Part number example :  M25-15-1-2-100-10 G1/2 400 bar. -> Reinforced refilling pressure gauge with dry electric contacts. Function 1-2 DN 100 . -> Mounting type 10 threaded fitting G ½ with measurement range 0 + 5800 psi  With shock absorbing liquid M25G-15-1-2 100-10 G ½" 400		PDF
DETECTOR ILS - 53	-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.

MICRO CIRCUIT BREAKER – 50	The pressure gauge mechanism is equipped with a micro circuit breaker with adjustable consign point and localized by an index.  This device works like a reversing switch.  P/N M50-3 – mechanism with 1 micro circuit breaker.  This device is only adaptable on pressure gauges DN100 with pressure from 58 to 5800 psi.  Cut-off capacity : 5A under 250V maxi / 50 Hz		PDF
MULTIFUNCTION TIME DELAY RELAYS - MSR	The use of these relays is obligatory in the following cases :  Pressure gauges with shock absorbing liquid.  Important vibrations and pulsations.  Strong cutoff capacity. The WE-Ex relays are utilized for applications in inherent safety.		PDF
