M-61-T Datasheet, PDF (1/4 Pages) List of Unclassifed Manufacturers – Non-Adjustable Flow Switches
Non-Adjustable Flow Switches
M-61-T Series
Fixed setting flow switch
with right angle flow and flare fittings
Features
• For corrosive and non-corrosive liquids or
gases
• Senses increasing or decreasing flow
• Very accurate custom flow settings
• Hermetically sealed
• All-PTFE switch with flare fittings
• Universal mounting available (using PTFE
coated spring)
Operation
The operating principle is based on a free floating magnetic
piston which responds only to the motion of fluids within the
line, not to static or system pressures. In the presence of fluid
flow, controlled movement of the piston actuates an external
hermetically sealed reed switch. This switch can be used to
actuate audible or visual alarms, as well as relays, or other
controls.
Applications
• Sample flow monitoring
• Alarm actuation
• Purge flows
• Loss of flow protection
• Semiconductor etch tools
• Laser cooling equipment
