Ashcroft A-Series pressure switches are designed for tough applications where conventional pressure switch designs often don't measure up. A rugged all 316 SS IP67 enclosure gives uncompromising protection over a wide temperature range for the most demanding applications. Materials of construction have been selected for long life. Precision snap acting micro switches are featured and fully encased to prevent moisture from corroding switch contacts. The switch, depending on range, is either an all welded 316 stainless steel diaphragm sealed piston design or a direct acting piston design sealed with a Buna-N or Viton O-ring. Applications include: Offshore oil rigs Chemical and petrochemical plants Pulp or paper mills Special equipment such as autoclaves and sterilizers Rail and heavy vehicle hydraulic and pneumatic braking applications Other special machinery and equipment applications
