The new SIL 3-capable Ashcroft A-Series miniature pressure switch is now available in an explosion-proof configuration for hazardous areas. With 316 stainless steel construction, an IP67-rated enclosure and an operating temperature range from -40 to 89 C (-40 to 192 F), the rugged dual-seal rated A-Series explosion-proof pressure switch stands up to the most extreme environmental conditions.

To ensure compliance to regional codes for explosion-proof devices, the A-Series explosion-proof switch has received agency approvals and certifications from FM, UL, ATEX, IECEx, CSA, and CRN. In addition to SIL 3 capability, it also conforms to CE and RoHS requirements.

Pressure ranges from vacuum through 7,500 psi are complimented with a broad selection of pressure inlet fittings. Additionally, the switch may be ordered with a fixed factory setpoint or in an alternate version that allows it to be adjusted in the field.
