The new Midland-ACS pressure switch from Rotork is specifically designed to withstand shock and vibration in critical duties found in the rail, commercial vehicle and industrial sectors. The compact and lightweight electro-mechanical design delivers accurate, repeatable and reliable performance for multiple applications including compressors and braking systems in ambient working temperatures ranging from -40ºC to +85ºC (-40ºF to +185ºF).
The robust and durable design of the pressure switch features a silicon rubber diaphragm suitable for neutral gases and liquid fluids. Working set-point pressures are selectable in four adjustable ranges from 0.2 – 2 bar up to 1.6 – 16 bar, with pre-set options also available. Maximum allowable inlet pressure is 24 bar.
IP65 environmental protection in accordance to EN 60529, including electrical connections, together with corrosion protection (salt spray) to ISO 9227, provides suitability for installation in exposed locations, whilst long-term reliability is further enhanced by UL & CSA approved triple layer gold plated micro-switch contacts. The pressure switch is shock and vibration tested in accordance to EN 61373 (Category 1 Class B).
