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
2
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-T4 -XW-F4WC-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 the serial number and we can help you.
You'll also find all hazardous certification information on the label.

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,
• 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
• The float(s) is/are oriented properly on the stem (See Figure 5.1 below). MPX-T floats are
 IMPORTANT: MPX-T level sensor MUST be installed according to drawing 9003468
(Hazardous Installation and Non-Incendive Wiring Drawing) in section 9 to meet listed
approvals. Faulty installation will invalidate all safety approvals and ratings.
Installation Instructions:
• If your sensor's stem and floats fit through the mounting hole, carefully lower the assembly
• If the floats do not fit, mount them on the stem from inside the vessel being monitored. Then
• For sensors with float stops, refer to the assembly drawing included with the sensor for float
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
• Connect wires to MPX terminals. Use crimped ferruls on wires, if possible.
• Replace housing cover.
• For lightning and surge protection on MPX-T4 models, either connect the grounding screw
See Electrical Connections and System Wiring Diagrams (section 6) for Modbus and 4-20 mA
