1 Introducon
The Pyxis LSP-X01 Series sensor is a pressure-based, submersible level sensor that provide connuous level
measurement up to 393 inches (32.8  or 10 m) with a 4–20mA analog and Bluetooth digital output. The
sensor is uniquely designed to be congured via the uPyxis® Mobile or Desktop App for mobile or PC based
devices. The sensor is powered by 24 VDC external power supply commonly provided by the device it
is connected to (ie. OEM controller or external power source). This submersible liquid level sensor plat-
form is well suited for water, wastewater, oil, and other non-corrosive or corrosive liquids. LSP-X01 Series
pressure transducer is available in 316LSS, PVC, and PVDF opons; suited for a wide variety of liquid ap-
plicaons. Each sensor comes equipped with 32 feet PTFE cable and the base unit from which the output
communicaon signal is terminated. See Selecon Guide below on unit opons with compable materials
of construcon.

4 Installaon
4.1 Tank Top and Mounng Bracket Installaon
The LSP-X01 Series sensor consists of a pressure transducer module (Figure 3) and a processor module (Fig-
ure 4). The two modules are connected by a 32.8- PTFE 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-X01 Series sensor.
Figure 3. Pressure Transducer Module Dimension, inch.
LSP-X01 Series User Manual [email protected] | [phone]

Figure 4. Processor Module Dimension, inch (mm)
The processor module of the LSP-X01 Series sensor can be installed to a 1” bulkhead ng on the top of
the tank. Alternavely, you may also use the LSP-X01 Series Mounng Bracket (P/N: 50770) for installaons
where top tank mount may be to too high for maintenance. In this format, the processor module is installed
in a locaon away from the tank top to take the advantage of the 32.8- cable. Each LSP-X01 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 5. LSP-X01 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.

4.2 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-X01 Series probe are internally connected.
Follow the wiring table below to connect the LSP-X01 Series probe to a controller:

6.4 Reading Screen
The Reading screen displays the current volume of liquid remaining and liquid level over me.
Figure 10.
6.5 Sengs Screen
The LSP-X01 Series sensor measures the hydrostac pressure created by the liquid level in the tank. Con-
ver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-X01 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.

8 Outputs
8.1 4-20mA Output Setup
The 4–20mA output of the sensor is scaled as:
• 4 mA = (Tank is Empty) = (Level is 0)
• 20 mA = (Tank is Full) = (Level is maximum height or volume)
The 4–20mA analog signal can be converted to one of three values (Level, Volume Remaining, or Volume
Consumed) in the controller receiving the output according to the above scale. For example, a nominal
100-gallon vercal tank, the maximum height is 36 inches. The tank volume is 100 gallons when it is lled
up to the maximum height 36 inches. The controller should be set up to convert 20 mA to 100 gallons, at
which the tank is full and the tank level is 36 inches.
LSP-X01 Series User Manual [email protected] | [phone]

*NOTE*The nominal capacity provided by the tank manufacturer may be greater than the
maximum safe (net or eecve) capacity that can be praccally lled. Please keep this in
mind as you congure your LSP-X01 Series sensor for praccal purposes.
9 Sensor Maintenance and Precauon
9.1 Methods to Cleaning LSP-X01 Series Transducer
For best performance, following the steps below to clean the submersible pressure transducer if necessary:
1. Hold the body of the transducer with one hand and carefully remove the protecve nose cap by
simply unscrewing it from the transducer body. Do not touch the sensor diaphragm and do not dry
the inside poron of the transducer, as you risk damaging the pressure sensor.
2. Place the transducer in a vercal posion with the sensing end facing downward in a bowl containing
Pyxis Probe Cleaning Soluon for approximately 1 minute.
3. Place the protecve nose cap in the same soluon for approximately 1 minute.
4. Rinse the bowl with clean water and wipe dry the external casing of the transducer and the protecve
nose cap.
5. Screw the protecve nose cap back into place on the transducer body.
The Pyxis Probe Cleaning Soluon is from the Inline Probe Cleaning Soluon Kit (P/N: SER-01) which can
be purchased at our online E-Store hps://pyxis-lab.com/product/st-series-probe-cleaning-kit/.

10 Regulatory Approval
United States
The LSP-X01 Series sensor has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protecon against
harmful interference in a residenal installaon. This equipment generates, uses and can radiate radio
frequency energy, and if not installed and used in accordance with the instrucons, may cause harmful
interference to radio communicaons. However, there is no guarantee that interference will not occur in
an installaon. If this equipment does cause harmful interference to radio or television recepon, which can
be determined by turning the equipment o and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separaon between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is con-
nected.
• Consult the dealer or an experienced radio/TV technician for help.
Canada
This device complies with Industry Canada license exempt RSS standard(s). Operaon is subject to the
following two condions: (1) this device may not cause interference, and (2) this device must accept any in-
terference, including interference that may cause undesired operaon of the device. Le présent appareil est
conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de licence. L’exploitaon est
autorisée aux deux condions suivantes: (1) l’appareil ne doit pas produire de brouillage, et (2) l’ulisateur
de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est suscepble
