1 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.
2 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-T5B-JI-F4SC-120-3D
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 the serial number and we can help you.
You’ll also find all hazardous certification information on the label.
5 Installation Guidelines & Instructions
The MPX should be installed in an area–indoors or outdoors–which meets the following conditions:
· Ambient temperature between -40°C and 85°C (-40°F to +185°F) · 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 chemicals incompatible with Titanium Grade 2 · 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. · No ignition hazards exist due to impact or friction with the titanium stem. · 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/are oriented properly on the stem (See Figure 5.1 below). MPX-T floats are
typically installed by customer.

indicating the top of the float. Remove sticker prior to use.
Figure 5.1
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.
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 ferruls on wires, if possible. · Replace housing cover. · For EMI protection on MPX-T4 and -T5 models, either connect the grounding screw (see Dimensions section 4) to an earth ground, or ensure that tank mounting of MPX is grounded.

7 General Care
Your MPX 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.
IMPORTANT: All repairs and adjustments of the MPX-T level sensor must be made by the factory. Modifying, disassembling, or altering the MPX-T is strictly prohibited.
8 Repair Information
If your MPX level sensor needs repair, contact us via email, phone, or online chat on our website. We will issue you a Return Material Authorization (RMA) number with instructions.
