2 Electric Liquid Level switches. Refer to separate instruction manuals when you require information regarding related valves, actuators, positioners, and accessories. Do not install, operate or maintain a 2100 Pneumatic or a 2100E Electric Liquid Level switch without being fully trained and qualified in valve, actuator and accessory installation, operation and maintenance. To avoid personal injury or property damage it is important to carefully read, understand, and follow all of the contents of this manual, including all safety cautions and warnings. If you have any questions about these instructions, contact your Emerson sales office or Local Business Partner before proceeding. 2100 and 2100E Liquid Level Switches Instruction Manual July 2018 D200119X012. Description The on off 2100 Pneumatic switch (figure 1) and the 2100E Electric switch (figure 2) operate shutdown valves or alarm systems when Liquid in a vessel reaches a predetermined Level .

3 The 2100 switch uses an externally mounted displacer that operates a nozzle flapper to vent the supply pressure when the switch is activated. The nozzle flapper has a soft seat for tight shutoff when the switch is in its normal position (flapper against the nozzle). The 2100E switch uses the displacer torque to activate and deactivate an Electric switch for positive on off service. The displacer on each type can withstand up to 1 1/2 times the maximum working pressure, allowing it to remain in the cage during hydrostatic testing. Unless otherwise noted, all NACE references are to NACE MR0175-2002. Figure 2. Fisher 2100E Electric Liquid Level Switch APPROXIMATE. SWITCHING POINT. X0682. Specifications Specifications for the 2100 and 2100E switches are shown in table 1. WARNING. This product is intended for a specific current range, temperature range and other application specifications. Applying different current, temperature and other service conditions could result in malfunction of the product, property damage or personal injury.
