The HFS FP intrinsically safe switch is a horizontal magnetic float switch for control and indication of a liquid level whilst in a potentially explosive atmosphere. Manufactured in 316L Stainless Steel, it is a horizontally mounted Liquid Level Sensor ideally suited to high temperature or pressure operation. It is also suitable for harsh environments and chemically aggressive liquids. It can be changed from Normally Open to Normally Closed operation to allow for sensing of high or low conditions by rotating the orientation of the body through 180\u00b0.<\/p>\n

Refer to certificate ExVeritas 14ATEX0427X for clarification of system suitability and conditions for safe use. This switch must be used in conjunction with an intrinsically safe barrier when used in a potentially explosive atmosphere.<\/p>\n
