Gage reading device available for larger wireless protocol
When Cypress Envirosystems brought out its interesting gage reading device, it seemed odd to me that the company used its own wireless protocol, rather than one of the established standards. Cypress has now brought out a version in cooperation with Honeywell Process Solutions using the OneWireless system, so the device can now operate in a larger network rather than with its own proprietary gateway.
The device mounts on existing analog gages and uses machine vision technology to “read” the gage and send the data back wirelessly. (The original version, which is still available, uses its own proprietary protocol and gateway.) Installing the reader can be done without shutting down the process, breaking pressure seals, or running wires. Sending data via the OneWireless system allows the data to be integrated into a larger control platform, rather than through manual readings.
“The Gage Reader network was up and running in approximately three hours. In the first two weeks of using it, we were able to detect and develop corrective measures for a potentially costly issue in our plant that we never suspected with our daily manual gauge rounds,” says Mike Long, control system supervisor at Tri-State Generation and Transmission.
Honeywell suggests that the device is ideal for temporary uses with consumable materials since it can be moved from place to place. For instance, plants can use it to read inventory levels for gas cylinders that require periodic replacement. By monitoring the cylinder levels, plants can proactively determine when to replace the cylinder without taking manual readings.
