Specifications
Available Configurations
Controller: On/Off electric control action with
intuitive Zero and Span Adjustments in SPDT dry
contact configuration
Sensor: Displacertype liquid level sensor for
mounting to side of vessel
Input
Type: Liquid level or liquidtoliquid interface
Level Change Required for Full Change in State of
Output: 5.0 to 559 mm (0.2 to 22 inches)
Vessel level differential gap (DG) is dependant on
factors such as valve sizing, actuator speed, rate,
liquid out flow, and vessel size. Contact your Emerson

Specific Gravity Limits
Minimum SG: 0.15
Maximum SG
PVC Displacer: 1.3
SST Displacer: 1.1
Electrical Rating (Output)
J easy-Drive actuator application: 7 mA@5 VDC
J Other applications: 1 amp resistive, 0.5 amp
inductive/28 VDC
Note: Use with easy-Drive after first being used in
other high power application is not recommended.
Power Consumption
Switch consumes no power to operate, so it has no
current leakage or voltage drop

Displacer Material and Maximum Sensor Working
Pressure
(3)
PVC Displacer: Consistent with CL1500 pressure
temperature ratings per ASME B16.34 up to
maximum pressure of 258.5 bar (3750 psig)
For PED (97/23/EC) maximum pressure limited to
200 bar (2900 psig)

ratings per ASME B16.34 up to maximum pressure of
99.3 bar (1440 psig)
Note: For slipon flange connection, maximum sensor
working pressure must be consistent with the flange
ratings
