Explosion Proof Flexible Stem Magnetostrictive Level Sensors

The MPXI-F is designed for level measurement in hazardous locations, especially in tall tanks up to 50 feet. It is ideal for applications in oil & gas storage, petrochemical processing, industrial wastewater, pulp & paper, and biotech & chemical facilities.

The MPXI-F is CSA, ATEX, and IECEx certified for hazardous locations, meeting strict safety standards for Class I Division 1 environments.

Unlike rigid sensors, the MPXI-F features a PVDF or 316L stainless steel flexible stem, allowing for crane-free installation in tall tanks, reducing costs and complexity.

Yes, the MPXI-F offers an option for up to seven temperature sensors along the probe, providing real-time temperature monitoring within the tank.

Yes, with Modbus RTU or 4-20mA outputs, the MPXI-F easily integrates with SCADA, PLC, and other industrial monitoring systems.

Here are the steps to get the sensor communication back as sensor #1 using the APG Modbus software and the RST-6001 (USB to RS485 converter). 

It’s essentially the same process below to establish communication. 

Establishing Communication:

1. On the APG Modbus software, go to Configure>Communication.
2. Make sure the USB box is checked; the Sensor Type is MPX-1/4 RS485 and the Sensor# ID is showing 1.
3. Click Save Configuration and then click Save.
4. Click on the Green “Start Communication” Button.

After communication has been established, use the second procedure to change the sensor address. 

Changing the Sensor Address:

1. Change Register 400 from 1 to the desired address number.
2. Click Send. At this point, you will see a Comm Bad. That’s ok, go to Step 3.
3. Click again on Configure>Communication.
4. Change the Sensor ID from 1 to the new address number.
5. Click Save Configuration and then click Save.
6. Click on the Green “Start Communication” Button.

Your MPX probe should be communicating to the software with its new address.
