Teleterm M2R wireless units
Omniflex has developed Teleterm M2R wireless units to pick up existing instrumentation signals and transmit them across the plant, or to connect remote areas of a plant to each other.
With distances up to 10km line-of-sight covered by a standard stubby antenna, the company claims the Teleterm M2R provides an easy-to-use wireless network extension for existing cabled installations, and provides a cost-effective control system for remote pump stop-and-start applications.
Due to being based on licence-free bands, and using FHSS (frequency hopping and spread spectrum) technology, the Teleterm M2R is immune to other radio devices, and can be integrated into cable-based networks by using the on-board standard Modbus port.
It allows multiple channels to share the same frequency, and its low power restricts the RF influence to localised areas of the plant.
