S71 Temperature Switches

The model S71 Temperature Switch comes with a rigid or semi-rigid thermal system and is suitable for setpoints between -40°C and +260°C with maximum working temperatures up to 270°C. (EAC certification is available on request).

VM 2/4 Pressure Switch – Volume Series

The VM pressure switch offers a compact and cost effective solution for any application where reduced space and resistance to aggressive atmospheres is necessary. Performance is assured by utilising Delta Mobrey’s proven sensor technology in a new simple, one-piece enclosure.

Key Features

  • Wellhead control safety shutdown systems
  • Water or gas deluge fire protection systems
  • Fuel and lubrication systems, as found on gas turbines, compressors and other rotating machinery
  • Valve actuators

The range of models available for these cost effective switches include: general purpose applications, or those outdoor applications such as marine where the atmosphere may be more aggressive. The model VM Pressure Switch is suitable for setpoints between 0 and 700 bar with maximum working pressures up to 1000bar. (EAC certification is available on request).

CS2/4 Pressure Switch – Compact Series

The Compact Series, (C S), switch has been designed to meet the specific requirements of panel applications, whether they be of the Wellhead Control, Hydraulic Power Unit or Chemical Injection Skid type.

Their compact, rugged, all stainless steel construction makes them especially useful in the cramped and harsh environmental conditions that these applications demand. Supplied as standard with hermetically sealed switch contacts and with field adjustable set-points up to 700 bar, the Compact Series of Switches also come with either Intrinsically Safe or Flameproof approvals for use in Zone 0 or Zone 1 hazardous areas respectively.

The model CS2 and CS4 Presure Switches are suitable for setpoints between 0.25bar and 700bar with maximum working pressures up to 1000bar. (EAC certification is available on request).
