Enhanced-Performance Gateway
Here's the new FieldConnex diagnostic gateway, which is designed to enhance interoperation between individual advanced diagnostic modules (ADMs) of a fieldbus infrastructure and the diagnostic manager in the oil field control room. It does so by allowing information to be exchanged in both directions via ethernet, enabling additional features such as remote setup of ADMs. ADMs monitor the quality of fieldbus communication for FOUNDATION fieldbus H1 and PROFIBUS PA networks.

By combining the gateway with the self-configuring setup of the diagnostic manager, all ADMs are identified automatically, and the software configures itself accordingly. This results in fewer configuration errors during installation and setup of the ADM infrastructure.

The combination of the FieldConnex ethernet gateway and diagnostic manager results in an intuitive monitoring system that provides insight into the fieldbus physical layer directly from the control room. With this technology, the physical fieldbus layer becomes fully transparent and can be managed for maximum availability without the need for detailed expert knowledge, the firm notes.

Differential pressure measurement added to unit

An addition to the nVision reference recorder enables the intrinsically safe, hand-held field calibrator to graph and record average and differential pressure data.

This most recent (and free) quarterly update now allows the nVision to display, record, and graph differential pressure to an accuracy of 0.025% of the differential reading up to 300 psi static, 0.05% up to 3,000 psi static, and 0.1% up to 10,000 psi static pressure. The nVision can also record 500,000 data points from each of its two modular sensors, simultaneously. It takes these measurements as frequently as every 0.1 sec, without any change in accuracy between –20° and 50° C.
