LOGAN, UT – Automation Products Group, Inc. (APG) introduces a new self-contained measurement and control solution featuring the new Series MDI Intrinsically Safe Modbus Display and new Series MPI Intrinsically Safe Magnetostrictive Level Probes.

MPI & MDI connection

Developed in tandem with each other, the MDI modbus display and the MPI level probe are designed to work together, creating a stand-alone, self-contained measurement and control solution for Class I hazardous locations. The battery-powered MDI display is not only rated for installation in Class I, Zone 1 areas, is it also rated to power a single Intrinsically Safe device installed in Class I, Zone 1 or 0 areas without the need for complex IS barriers or explosion-proof conduit. Similarly, a single MPI probe can be installed in a Class I, Division 1 or Class I, Zone 0 location and connected directly to an MDI display. For stand-alone measurement-and-display in Hazardous Locations, an MDI and MPI greatly simplify both the amount of equipment needed and the installation procedures.

For more complicated scenarios, an MDI display with an auxiliary connection can be used with a passive monitoring system to provide system-wide access to the readings from the MPI probe. While a barrier is not required between the MDI display and MPI probe, an Intrinsically Safe barrier is required between the MDI display and the external monitoring system. The external system can only passively read the MDI display. However, the external system can be set to provide a “Wake Up” input to the MDI display, preserving the life of the battery powering both the MDI display and the MPI probe.

Already known for Explosion-proof Magnetostrictive Level Probes, APG is expanding its offerings to include Intrinsically Safe magnetostrictive level probes. Available across all the same stem types as the Explosion-proof probes, the MPI probes provide the precision output and control parameters of Modbus with the installation ease of Intrinsically Safe devices.
