Fisher 2100 Liquid Level Switches
Fisher 2100 on/off pneumatic switch and 2100E electric switch sense high or low liquid levels. The 2100 and 2100E switches use a displacer-style sensor located in an external cage that mounts on the outside of a vessel. Unless otherwise noted, all NACE references are to NACE MR0175-2002.
- The 2100 and 2100E switch construction comes in a left-hand as well as a right-hand mounting version.
- The switch is isolated and sealed from the process through a corrosion-resistant displacer and torque tube assembly for maximum reliability.
