Sirco Series 2000 Medium Pressure Range Brochure

MEDIUM PRESSURE RANGE – SERIES 2000 - 1 - Leaflet 12/10 MODELS: 2001 Single Switch, Differential Non Adjustable 201 Single Switch, Differential Adjustable 2002 Two Switch, Differential Non Adjustable 202 Two Switch, Differential Adjustable on 1st Switch Only All models are available as either Pressure or Vacuum sensitive switches and cover the range -1 to +210 Barg in a group of 12 basic models. Controls can be supplied with varying degrees of protection, and with various approvals for use in Explosion proof/Flameproof areas. (Refer to list for options). More detailed information on these approvals can be found in the relevant sections of this catalogue. Models falling within the range 0 to 1 Barg can be supplied as Vacuum switches (see code guide). Materials used in the manufacture of sensing units and pressure chambers are according to customer requirements and operational application. All switches are fitted with a mounting bracket as Standard (except Flanged Controls). All switches are available with internal or external set point adjustment (External Adjustment is Standard). For accuracy class and zone refer to leaflet 03/09.
