Liquid level
Minimum Process Liquid Specific Gravity
0.5 (consult your Emerson sales office
or Local
Business Partner for specific gravity below this value)
Output Signal
2100 Switch: Output equal to supply pressure when
the switch is in the normal
position (flapper against
nozzle). Output reduced to approximately
atmospheric pressure, depending upon size of the
bleed orifice and piping configuration, when the
switch is activated
2100E Switch: Same as supply signal
Supply Signal
2100 Switch: J 2.1 to 4.1 bar (30 to 60 psig), J 4.1
to 6.9 bar (60 to 100 psig), or J 6.9 to 10.3 bar (100
to 150 psig)
2100E Switch: 11 amperes, 1/4 horsepower at
125/250 volts AC; 5 amperes resistive, 3 amperes
inductive at 28 volts DC
Supply Medium (2100 Switch)
Air or Natural Gas
Steady‐State Air Consumption

/hr (1.0 scfh) for all supply
pressures when the liquid level is 25.4 mm (1 inch)
below the normal switch position (flapper against
nozzle) for high‐level switching or 25.4 mm (1 inch)
above the normal switch position for low‐level
switching
