Ultrasonic Liquid Level Switch

LU10

Application

CSA approved for use in hazardous locations, the
intrinsically safe ultrasonic level switch provides high
or low liquid level detection of chemical, solvent or
low viscosity petroleum based liquids with a 1A relay
output. Media examples include hydrochloric acid,
acetone and diesel fuel oil. The submersible PP or PFA
level switch sensor is universally mounted through the
tank wall or inside the tank, and connected to a PLC
or relay controller.

Features

CSA approved intrinsically safe for use in
hazardous environments

Submersible polypropylene or PFA Teflon®
sensor and cable for corrosive liquids

60VA SPST relay selectable NO or NC via power
supply wiring polarity

Compatible with Smart Trak and Switch-Pak
installation fittings

Key Benefits

Ideal for use as a high or low level switch in
classified applications

Well suited for use in highly corrosive liquids

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
non-latching 10A relay for high or low level alarm. For field mount installation, add a
single or dual indicator NEMA box.

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
control. The optional flash alarm brings attention to alarm conditions. Package this
level controller with our liquid level switch sensors and fittings.

NOTES

To special order a 25’ (7.6m) or 50’ (15.2 m) level sensor cable, place the

1)

cable length at the end of the part number (ie: LU10-1305-25’). For PP,

add $30 for 25’ (7.6m) or $60 for 50’ (15.2m) to the price. For PFA, add

$200 for 25’ (7.6m) or $400 for 50’ (15.2m) to the price.

The short Metric level sensor has conical Rp threads on both sides of the

2)

wrench flat. The long Metric level sensor has straight G threads on the

sensing side and conical Rp threads on the cable side of the wrench flat.
