Pressure and differential pressure switch Type 4ADS-10 Technical data trowalised; painted to special order Pressure connection 2 female threads Va" pipe Application Differential pressure switches 4ADS-10 are used mainly for monitoring air and oil filters in compressor installations. Because of their rugged construction they have numerous additional applications in all areas of process technology where differential pressures have to be monitored. The units can also be used as pressure or vacuum switches by connecting up only one of the pressure connections. Type designation Pressure instrument surface mounting pressure and differential pressure switch housing 100 mm dia. Restrictor in pressure duct sintered disc with restriction hole with Code /01 acrilonitrile-butadiene rubber (NBR) resistant to: Diesel fuel, mineral oil, oilbearing air, heating oil, water /01 restrictor in pressure duct /48 switching points vacuum switching differential 10% of switching point setting /50 Protection IP 54 Pressure and differential pressure switch Type 4ADS-10/47/50 Switching point: 2 bar Two aluminium die-cast housing shells form two independent pressure chambers in conjunction with a separating diaphragm, rivetted pressure plates and springs. Cable entry Pgll cable gland Electrical connection faston tags 6.3 x 0.8 mm to DIN 46 248/A for angle connectors single-pole changeover microswitch (CSA and UL approval) Operating position Switching point permanently set at the factory The exact value of the switching point must be specified when ordering. Switching point accuracy Switching differential normally 30% of switching point setting Code /49:10% of switching point setting Static pressure Operation Achange of pressure in the pressure chambers causes axial movement of a plunger. Asingle-pole microswitch is operated when a factory-set pressure difference has been reached. Pressure and differential pressure switch switching points normally from 50 mbar to 6 bar Vacuum switch, Code /48 from -50 mbar to -800 mbar. overload limit: -1 bar Contact rating Permitted ambient temperature
