Vibration Liquid Level Switch
LZ12
Application
The general purpose vibration level switch provides high
or low liquid level detection of dirty liquids or those with
light to medium coating or scaling characteristics with a 1A
relay output. Media examples include wastewater, diluted
caustic soda and copper sulfate. For optimum performance,
the sensor automatically adjusts for coating build up, and if
necessary, outputs a proactive maintenance alarm to request
cleaning. The submersible PP-Ryton® level switch sensor is
universally mounted through the tank wall or inside the tank,
and connected to a PLC or relay controller.
Features
Automatic coating adjustment optimizes sensor
performance
Submersible Ryton® sensor with polypropylene
cable for corrosive liquids
Maintenance alarm proactively alerts user if
sensor cleaning is required
60VA SPST relay selectable NO or NC via power
supply wiring polarity
Compatible with Smart Trak and Switch-Pak
installation fittings

Remote Level Controller
The general purpose remote level controller is offered in three configurations for
pump and valve control. The LC40 accepts one level sensor input and provides one
10A relay. The LC41 accepts two level sensor inputs and provides one latching 10A
relay for automatic fill or empty control. The LC42 accepts three level sensor inputs
with one latching 10A relay output for automatic fill or empty control, and a second
LC4X
non-latching 10A relay for high or low level alarm. For field mount installation, add a
single or dual indicator NEMA box.
Key Benefits
Ideal for coating, scaling or crystalizing liquids
Sensor measures and adjusts for material build
up over time
Plastic vibration sensor is well suited for use in
corrosive liquids
SWITCH-PRO™
Compact Level Controller
The general purpose compact level controller is offered in two configurations for
pump and valve control. The LC10 accepts one level sensor input and provides
one 16A relay for high level control or low level control. The LC11 accepts two
level sensor inputs and provides one latching 16A relay for automatic fill or empty

NOTES
To special order a 25’ (7.6m) or 50’ (15.2 m) level sensor cable, place
1)
the cable length at the end of the part number (ie: LZ12-1405-25’).
Add $30 for 25’ (7.6m) or $60 for 50’ (15.2m) to the price.
The metric level sensor has straight G threads on the sensing side,
2)
and conical Rp threads on the cable side of the wrench flat.
