Description
The MPX series magnetostrictive level sensor provides highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. It is certified for installation in hazardous areas in the US and Canada by CSA for Class I, Division 1 & 2 and Class I, Zones 1 and 2 environments.
How To Read Your Label
Each label comes with a full model number, a part number, and a serial number.
The model number for the MPX will look something like this:
SAMPLE: MPX-R3-ZY-F2.5WB-120
The model number correlates with all the configurable options and tells you
exactly what you have.
Compare the model number to the options on the datasheet to identify your
exact configuration.
You can also call us with the model, part, or serial number and we can help
you.
You’ll also find all hazardous certification information on the label.

Installation Guidelines & Instructions
The MPX should be installed in an area–indoors or outdoors–which meets the following conditions:
- Ambient temperature between -40°F and 185°F (-40°C to 85°C)
- Relative humidity up to 100%
- Altitude up to 2000 meters (6560 feet)
- IEC-664-1 Conductive Pollution Degree 1 or 2
- IEC 61010-1 Measurement Category II
- No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.)
- Ample space for maintenance and inspection
Additional care must be taken to ensure:
- The probe is located away from strong magnetic fields, such as those produced by motors, transformers, solenoid valves, etc.
- The medium is free from metallic substances and other foreign matter.
- The probe is not exposed to excessive vibration.
- The float(s) fit through the mounting hole. If the float(s) does/do not fit, it/they must be mounted on the stem from inside the vessel being monitored.
- The float(s)/is oriented properly on the stem (See Figure 5.1 below). MPX-E floats will be installed by the factory. MPX-R floats are typically installed by customers.
** IMPORTANT:** Floats must be oriented properly on the stem, or sensor readings will be inaccurate and unreliable. Untapered floats will have a sticker or “N” indicating the top of the float. Remove sticker prior to use.
Installation Instructions:
- If your sensor’s stem and floats fit through the mounting hole, carefully lower the assembly into the vessel, then secure the sensor to the vessel.
- If the floats do not fit, mount them on the stem from inside the vessel being monitored. Then secure the sensor to the vessel.
- For sensors with float stops, refer to the assembly drawing included with the sensor for float stop installation locations.
- For MPX-E Chemical, ensure the probe is concentric with fitting so as not to scrape the chemical-resistant coating off against threads of the fitting.
Electrical Installation Instructions:
- Remove the housing cover of your MPX.
- Feed system wires into MPX through 3/4” NPT conduit openings. Fittings must be UL/CSA Listed for CSA installation and IP65 Rated or better.
- Connect wires to MPX terminals. Use crimped ferrules on wires, if possible.
- Replace housing cover.
- For EMI protection on MPX-E4 and MPX-R4 models, either connect the grounding screw (see Dimensions section 4) to an earth ground or ensure that the tank mounting of MPX is grounded. See Sensor and System Wiring Diagrams (section 6) for Modbus and 4-20 mA wiring examples.
IMPORTANT: WARNING — A SEAL SHALL BE INSTALLED WITHIN 18 inches OF THE
ENCLOSURE;
AVERTISSEMENT – – UN SCELLEMENT DOIT ETRE INSTALLÉ A MOINS DE 18 inches
DU BOITIER.

General Care
Your level sensor is very low maintenance and will need little care as long as
it was installed correctly. However, in general, you should periodically
inspect your MPX unit to ensure the stem is free of any heavy buildup that
might impede the movement of the float(s). If sediment or other foreign matter
becomes trapped between the stem and float(s), detection errors can occur.
If you need to remove the floats(s) from the stem of your MPX, be sure to note
the orientation of the float(s) prior to removal. This will help ensure proper
re-installation of the float(s).
Also, ensure that the housing cover is snuggly secured. If the cover becomes
damaged or is misplaced, order a replacement immediately.

4-20 mA Programming Wiring
IMPORTANT: MPX level sensor MUST be installed according to drawing
9003468 (Hazardous Installation and Non-Incendive Wiring Drawing) in section 9
to meet listed approvals. The faulty installation will invalidate all safety
approvals and ratings.
**IMPORTANT:** All repairs and adjustments to the MPX level sensor must
be made by the factory. Modifying, disassembling, or altering the MPX is
strictly prohibited.
