Description
1
The MPX series magnetostrictive level sensor provides highly accurate and repeatable level and
temperature readings in a wide variety of liquid level measurement applications, including API 18.2
Custody Transfer. It is certified for installation in hazardous areas in the US and Canada 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-T5-JI-F4SC-180-AP
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.

Installation Guidelines & Instructions
5
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 chemical corrosive to stainless steel (such as NH
• No chemicals incompatible with Titanium Grade 2 for MPX-T
• 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-R and MPX-T
floats are typically installed by customer.
 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. 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
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.
• Connect wires to MPX terminals. Use crimped ferruls on wires, if possible.
3/4" NPT
• Replace housing cover.

• For EMI protection, either connect the grounding screw (see Dimensions section 4) to an
Housing
earth ground, or ensure that tank mounting of MPX is grounded.
