More About this Item

Standard Low-Flow Switches are normally closed (NC) but can be wired for normally open (NO). Typical applications include chemical process and vapor deposition systems; industrial gas lines; pollution control monitoring; atmospheric furnaces; and leak detection.
Choose from a brass switch (32929-10, -14) for pressures up to 1500 psi, or a switch made from PTFE (32929-12, -16) for good chemical compatibility. Wetted materials are brass, epoxy, and Viton for models 32929-10 and -14; PTFE for models 32929-12 and -16. Repeatability is ±2%. Measure 1-¾''W x 2-5/8''H x ¾''D.

      A:

      To change the condition of the switch, you would loosen the set screws and move the reed switch assembly. To set the switch as normally open, you would move the switch downward until the contact closure occurs. Then move it upward until switch contacts open. If you want to wire it as normally closed, you would move the switch downward until contacts close and reopen. Then move the assembly upward until contacts close. Once your switch assembly has been positioned properly, gently tighten the set screws and test the switch to be sure it is functioning properly.
