1 Description
The MPI 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 Class I, Division 1, and Class I, Zone 0 hazardous areas in the US and Canada by CSA, and ATEX and IECEX for Europe and the rest of the world.
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 MPI will look something like this:
SAMPLE: MPI-R5-ZY-P3SB-120-4D-N
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.
3 Warranty
This product is covered by APG's warranty to be free from defects in material and workmanship under normal use and service of the product for 24 months. For a full explanation of our Warranty, please visit https://www.apgsensors.com/about-us/terms-conditions. Contact Technical Support to receive a Return Material Authorization before shipping your product back.

5 Installation Guidelines & Instructions
The MPI 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.) (Not applicable to plastic-
type stem options) · 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/are oriented properly on the stem (See Figure 5.1 below). MPI-E floats will be
installed by the factory. MPI-R floats are typically installed by customer.

Taper

IMPORTANT: Floats must be oriented properly on the stem, or sensor readings will be inaccurate and unreliable. Untapered floats will have a sticker or etching indicating the top of the float. Remove sticker
UP prior to use.

ATEX Stated Conditions of Use: · Under certain extreme circumstances, the non-metalic parts incorporated in the enclosure of this equipment may generate an ignition-capable level of electrostatic charge. Therefore the equipment shall not be installed in a location where the external conditions are conducive to the build-up of electrostatic charge on such surfaces. In addition, the equipment shall only be cleaned with a damp cloth. · The enclosure is manufactured from Aluminum. In rare cases, ignition sources due to impact and friction sparks could occur. This shall be considered during installation.
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's mounting option 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.
Warning! The Kynar stem is susceptible to thermal expansion when the process temperature exceeds 73°F / 23°C. This expansion can be calculated as follows: Expansion = (Max Process Temperature (°F) -73)*.000108 * Kynar Stem Length). This is the distance that must be left between the end of the Kynar stem and the tank bottom at the maximum process temperature.
Electrical Installation Instructions: · Remove the housing cover of your MPI. · Feed system wires into MPI through conduit openings. Fittings must be UL/CSA Listed for CSA installation and IP65 Rated or better. · Connect wires to MPI terminals. Use crimped ferrules on wires, if possible. · Replace housing cover.
See Sensor and System Wiring Diagrams (section 6) for Modbus wiring examples.

7 General Care

8 Repair Information

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 MPI 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 MPI, be sure to note the orientation of the float(s) prior to removal. This will help ensure proper re-installation of the float(s).

If your MPI 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.
· Phone: 888-525-7300 · Email: sales@apgsensors.com · Online chat at www.apgsensors.com

Also, ensure that the housing cover is snuggly secured. If the cover becomes damaged or is misplaced, order a replacement immediately.
