The Pyxis LS-200 is a general-purpose ultrasonic sensor. It provides connuous level measurement up to 86
inches (7.2 or 2.2 m) with a 4–20mA output, RS-485, and Bluetooth digital outputs. It can be congured
via the uPyxis® App on your mobile phones or computers. The sensor is powered by a 24 VDC external
power supply. This non-contact liquid level sensor is well suited for corrosive liquids and can be used for
industrial and municipal liquid storage and chemical feed applicaons.

4 Installaon
4.1 Tank Top Installaon and Precauons
The sensor should be installed to a 1-inch bulkhead ng on the top of the tank. The major dimensions of
the sensor are shown in Figure 2. If a at horizontal surface is not available on the top of the tank, please use
a self-aligning bulkhead ng so that the sensor can be adjusted to be perpendicular to the liquid surface.
• Install and adjust the sensor to be perpendicular to liquid surface
• Installaon locaon shall not be too close to container wall to avoid interference.
• The sensor has a 3.94 inch (10 cm) dead zone (DZ). Raise the probe to avoid the DZ if desired
• Do not install in a locaon which will cause the ultrasonic wave to be obstructed
• Do not install the sensor in a vacuum environment

4.2 Wiring
If the power ground terminal and the negave 4–20mA terminal in the controller are internally connected
(non-isolated 4–20mA input), it is unnecessary to connect the 4–20mA negave wire (green) to the 4–20mA
negave terminal in the controller. If a separate DC power supply other than that from the controller is used,
make sure that the output from the power supply is rated for 22–26 VDC @ 65 mA.
*NOTE*The negave 24V power terminal (power ground) and the negave 4–20mA ter-
minal on the LS-200 are internally connected.
Follow the wiring table below to connect the LS-200 to a controller:

5 Instrument Overview
The indicators on the top of the sensor (Figure 4) are used to indicate power status and Bluetooth connec-
on status.
