Description

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

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-P2ST-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.

Dimensions

IMPORTANT: WARNING — A SEAL SHALL BE INSTALLED WITHIN 18 inches OF THE ENCLOSURE;
DANGER: OPEN CIRCUIT BEFORE REMOVING COVER or KEEP COVER TIGHT WHILE CIRCUITS ARE ALIVE;
DANGER: WARNING — EXPLOSION HAZARD — SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY FOR CLASS I, DIVISION 2;

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 chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.) for MPX-R
• 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 drawing 9003468 (Hazardous Installation and Non-Inc endive 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 UUCSA Listed for CSA installation.
• Connect wires to MPX terminals. Use crimped ferrules on wires, if possible.
• Replace housing cover.
• For EMI protection, either connect the grounding screw (see Dimensions section 4) to an earth ground, or ensure that tank mounting of MPX is grounded.

See Modbus System Wiring Diagrams (section 6) for Modbus wiring examples.

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.
DANGER: WARNING — EXPLOSION HAZARD — DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS;
Warning: — The model MPX-T contains titanium in excess of 7.5% for Group II and care needs to be taken to avoid an ignition hazards due to impact or friction;

Sensor and System Wiring Diagrams

Modbus System Wiring

Note: Earth Ground terminal is factory connected to internal housing ground lug.
NOTE: For APG Modbus programming instructions, please see MPX user manual. APG Modbus software can be downloaded from www.apgsensors.com/support.

Modbus System Wiring with RST-6001

Note: An independent +12-24 Vdc power supply is required when using an RST-6001 Modbus Controller. The RST-6001 can only supply ±5 Vdc, not the +12-24 Vdc required by the MPX.
Note: Earth Ground terminal is factory connected to internal housing ground lug.
IMPORTANT: For EMI protection, either connect the grounding screw (see section 4) to an earth ground, or ensure that tank mounting of the MPX is grounded.
IMPORTANT: Refer to section 9 for Hazardous Location Wiring.

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 snuggle secured. If the cover becomes damaged or is misplaced, order a replacement immediately.
DANGER: WARNING — POTENTIAL ELECTROSTATIC CHARGING HAZARD – CLEAN ONLY WITH A DAMP CLOTH;
