1 Introducon
The Pyxis LSP Series sensor is a pressure-based, submersible, level sensor. It provides connuous level
measurement up to 393 inch (32.8  or 10 m) with a 4-20mA analog and Bluetooth digital output. It can be
congured via the Pyxis’s uPyxis® Mobile App or uPyxis® Desktop App. The sensor can be powered by 4 AA
Li/SOCl2baeries or a 24 VDC external power supply. This baery-powered and Bluetooth-enabled level
sensor is ideally suited for applicaons where signal/power wiring may be dicult or unavailable to install.
A 1.3-inch OLED display and four push-buons are also included in the sensor for display and setup. The
base product of the series, the LSP-100, is well suited for water, waste water, oil, and other non-corrosive
liquid. Other sensors in the LSP Series are available and suited for more corrosive liquids. See Figure ??
below on alternave units with compable materials of construcon.

3 Unpacking Instrument
Remove the instrument and accessories from the shipping container and inspect each item for any damage
that may have occurred during shipping. Verify that all accessory items are included. If any item is missing
or damaged, please contact Pyxis Lab Customer Service at [email protected].
3.1 Standard Accessories
• LSP Series Flying Lead Adapter Cable (10 ) P/N: 50774
• User Manual available online at www.pyxis-lab.com/support.html

4 Installaon
4.1 Baery Installaon
The LSP Series sensor can be powered by four (4) AA Li/SOCl2baeries if a 24 VDC supply is not available.
These baeries are unique and available through Pyxis Lab (P/N: 50731). Typical baery life aer replac-
ing a new baery set is about 6 months with a 60 minute measurement interval. The LSP Series baery
compartment is shown in Figure 2.
*NOTE*Do NOT use rechargeable nickel cadmium (NiCad) or rechargeable lithium baer-
ies.
Figure 3. Baery Installaon
LSP Series User Manual [email protected] | [phone]

Follow the steps below to install or replace baeries:
1. Separate the upper poron of the sensor by loosening the four hex bolts with the screw driver in-
cluded in the package. Reach the baery holder by hand and pull it out carefully. Pay careful aenon
to the connecon wire between the cover and main sensor body when separang them.
2. Follow the posive and negave signs and insert baeries rmly into the baery holder. Please note
that four baeries need to be replaced, two on each side of the baery holder. Replace the four
baeries together rather than parally.
3. Place the baery holder back to the main sensor body and secure it rmly.
4. Place the upper poron of the sensor back to the sensor main body. Make sure that the sealing O-
ring is lying at in the groove of the main sensor body. Failure to do so may result in water/moisture
damage to the sensor.
5. Firmly ghten the hex bolts to prevent the LSP Series sensor from accidentally being turned on or o
due to vibraon.
4.2 Tank Top and Mounng Bracket Installaon
The LSP Series sensor consists of a pressure transducer module (Figure 3) and a display/processor module
(Figure 4). The two modules are connected by a 32.8- PVDF cable. The cable provides electric connecon
between the two modules and serves as an air vent to the transducer.
*NOTE*Altering the cable can cause permanent damage to the LSP Series sensor.
Figure 4. Pressure Transducer Module Dimension, inch.
LSP Series User Manual [email protected] | [phone]

Figure 5. Display/Processor Module Dimension, inch (mm)
The display/processor module of the LSP Series sensor can be installed to a 1-inch bulkhead ng on the top
of the tank. Alternavely, you may also use the LSP Series Mounng Bracket (P/N: 50770) for installaons
where top tank mount may be to too high for visual display vericaon. In this format, the display/processor
module is installed in a locaon away from the tank top to take the advantage of the 32.8-foot cable and have
visibility to the display. Each LSP Series sensor is also shipped with a 2” male NPT bulkhead adapter with
internal cable gland (pre-installed on transducer cable) for installaons requiring a sealed bulkhead/cable
ng as shown in Figure 5.
Figure 6. LSP Series Mounng Bracket (P/N: 50770) w/ 2” male NPT bulkhead adapter
The following is a list of installaon guidelines and precauons:
1. Leave a 1-inch space between the transducer module and the tank boom surface.
2. Do not remove the protecve cap and expose the diaphragm directly to the liquid. This may cause
permanent sensor damage.
3. Ensure that installaon is not near large vibraon locaons.

4.3 Wiring
If the power ground terminal and the negave 4-20mA terminal in the controller are internally connected
(non-isolated 4-20mA input), it is unnecessary to connect the 4-20mA negave wire (green) to the 4-20mA
negave 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 @ 65mA.
*NOTE*The negave 24V power terminal (power ground) and the negave 4-20mA ter-
minal on the LSP Series probe are internally connected.
Follow the wiring table below to connect the LSP Series probe to a controller:

*NOTE*When the LSP Series sensor is powered through the above 24 VDC wiring congu-
raon, the baeries should be removed from the compartment.
5 Instrument Overview
5.1 Funcon Buons
The buons on top of the LSP Series sensor (Figure 6) are used to select one of four display modes, one of
three Bluetooth modes, and one of four measurement modes.
*NOTE*The funcon buons are not used to congure the sensor. For LSP Series sensor
conguraon, see either the Setup and Conguraon with uPyxis® Mobile App secon or
the Setup and Conguraon with uPyxis® Desktop App secon of this manual.

• Power On: Hold the power buon for 1 second
• Power O: Hold the power buon unl OLED display is turned o
LSP Series User Manual [email protected] | [phone]

• Display Wakeup: Hold the power buon for 1 to relight OLED display (Only the power buon has this
funcon)
Working Mode Buon : This buon cycles through the dierent measurement intervals pre-programmed
into the LSP Series sensor. The current measurement interval is displayed on the top-right corner of the
OLED screen:
• CONT: Connuous measuring
• 10s: Measurement every 10 seconds
• 30s: Measurement every 30 seconds
• 3m: Measurement every 3 minutes
• 30m: Measurement every 30 minutes
• 1h: Measurement every 60 minutes
• STOP: Stop measuring
Other measurement intervals can also be congured on the uPyxis® App.
Display Mode Buon : This buon cycles through four display modes and two system informaon
modes. For more details, see the OLED Display secon of this manual.
Bluetooth Mode Buon : This buon cycles through three Bluetooth modes:
• B: Beacon mode, allows mulple Bluetooth-enabled devices to read the LSP Series sensor’s broad-
casng results at the same me.
• P: Peripheral mode, used for sensor conguraon and data download only. The LSP Series sensor can
only pair with a single Bluetooth-enabled device while in this mode.
• Absence of : Shutdown mode, disables Bluetooth communicaon with the LSP Series sensor.

5.2 OLED Display
The OLED display supports four display modes and two system informaon modes as shown in the following
gures. Press the display mode buon to switch modes.

*NOTE*The date/me will reset to 2000-01-01 00:00:00 on every power-on operaon.
When the LSP Series sensor is connected to a phone or PC via the uPyxis® App, the date/me
will be automacally set according to the phone or PC’s clock. The wrong system date/me
does not aect the sensor measurement funcon, but the me stamp in the data log will
be incorrect.

LSP Series User Manual [email protected] | [phone]

6.5 Sengs Screen
The LSP Series sensor measures the hydrostac pressure created by the liquid level in the tank. Converng
this measured pressure value to other parameters such as the tank level and the remaining liquid volume
in gallons requires the tank volume capacity, the tank maximum liquid height measured from the boom of
the tank to the liquid surface when lled to the rated capacity, and the density of the liquid. Measurements
assume the tank has a uniform horizontal cross-secon. To convert the measured pressure to volumetric
informaon, the LSP Series sensor requires the user to enter three parameters via the uPyxis® Mobile App’s
Seng screen:
•Tank Volume (rated volume capacity of the tank)
•Max Level Height (from the boom of the tank to the liquid surface when lled to the rated capacity)
•Density (of liquid in lb/gal)
From the Sengs screen, you can also set the Device Name,Display Unit, and Log Period (me, in seconds,
between two measurements). To save your seng changes, press Set Device.
*NOTE*The LSP Series sensor must be in Peripheral mode (P) to change sengs.
