Rosemount 702 Wireless Discrete Transmitter

The Rosemount 702 WirelessHART Discrete Transmitter enables Saudi Aramco and SABIC to monitor on/off switch states — high-level switches, pressure switches, vibration switches, and valve position indicators — wirelessly, eliminating cable installation costs at remote or difficult-to-wire field locations. In Saudi Aramco's brownfield facilities built in the 1970s and 1980s, adding new discrete monitoring points often requires trenching through existing paved roads and congested cable trays, making wireless the only economically practical option. The 702's IECEx and ATEX Zone 1 certification allows safe installation in Saudi Aramco classified hazardous areas without compromising safety system integrity.

The 702 transmitter accepts two independent discrete inputs simultaneously, allowing a single wireless device to monitor both a level switch and its associated vent valve position at a Saudi Aramco separator — halving the number of wireless devices needed for a complete monitoring loop. WirelessHART self-organizing mesh network capability means the 702 automatically routes around obstacles and other field devices at Saudi Aramco's complex refinery and gas plant environments, providing reliable communication even in the congested processing equipment of Ras Tanura and Abqaiq.

The 702's FIPS 197 AES-128 encryption ensures wireless data security that meets Saudi Aramco's cybersecurity requirements for connected field devices under IEC 62443. Saudi Aramco's Digital Transformation initiative requires all new field monitoring points to support data connectivity for predictive maintenance analytics — the 702's WirelessHART link to Emerson's AMS Wireless SNAP-ON module enables integration with Saudi Aramco's OSIsoft PI historian for monitoring trend analysis. The transmitter's 10-year lithium battery provides maintenance-free operation at Saudi Aramco remote monitoring points.

Razz Middle East provides complete 702 wireless monitoring systems including WirelessHART gateways, antenna extension kits for long-range Saudi desert applications, and DeltaV or AMS integration configuration services. Our wireless specialists perform site surveys at Saudi Aramco facilities to design optimal WirelessHART mesh network topology before equipment delivery.
