STURDY, ROBUST AND PRECISE
  HIGH STATIC PRESSURE
  VACUUM, PRESSURE & COMPOUND RANGES
  CHOICE OF DIAPHRAGM MATERIAL

B-Series Pressure / Vacuum Switches are designed for high proof pressure to handle pressure from vacuum to 210 kg/cm1. B-Series switches use a diaphragm sealed piston actuator. As the pressure on the calibration piston increases, the adjusted spring force is over-come and the snap action switch is actuated. The piston is sealed from the process by a diaphragm (Actuator Seal), Choice of diaphragm materials offers compatibility with virtually any medium.

The rugged diaphragm sealed piston actuator provides setpoint repeatability of 0.5%. The enclosure is die-cast Aluminium and is available in weatherproof and flameproof versions (table 'A'). A wide variety of SPDT (Single) and 2xSPDT (Dual) snap action switches are available to meet many electrical load requirements (Table 'B').

Applications include: Pumps, Compressors, Heat Exchangers, Boilers, Marine Equiment, Lube Systems, Filters, Degreasers, Evaporators, Textile Machinery, Heating & Air Conditioning Systems, Food Processing, Het Tracing, Fire Fighting, Bottling, Bilk Conveying, Packing & Filling, Furnace, Blowers and Air Dryers, ets.,
