Flow Switch Immune to Rapid Temperature Changes
Product Announcement from ifm efector inc.
A fast response time of 10ms is ideal for cycling applications and the durable switch has a minimum of 10 million switching cycles. The switch is immune to rapid temperature changes of the media and an integrated check valve prevents back flow. The switch is able to be bench setup and has an accuracy rate of +/- 5% of full range.
The compact flow switch includes an inductive proximity switch mounted in an adjustment dial that senses the position of a spring-supported piston. When the adjustment dial is turned, the position of the inductive sensor moves closer or farther away from the top of the piston. The position of the piston is proportionate to the flow rate. The spring resets the piston to its initial position with decreasing flow of the media. This allows the sensor to be mounted in any horizontal or vertical position and function as a check valve. The switch can be set up to 26 gpm, and the switch's LED indication provides operating status at a glance.
The 24 VDC units have a PNP switching output, pressure rating of 363 psig, and an M12 connector for power. Two units are available: Part number SBN333 has a setting range of 0.26...6.6 gpm with 3/4" NPT process connection; and part number SBN346 with a setting range of 1.32...26.4 gpm and a 1" NPT process connection.
