The Model AI digital pressure gauge carries FM approval as intrinsically safe for Class I, II, III; Div 1, 2; Group A, B, C, D, E, F, and G.

The AI is available in ranges of 0-15 to 0-10,000 psi with gauge, absolute, vacuum, or compound reference. Accuracy of 0.05% coupled with an enhanced resolution, 41/2-digit display helps suit the gauge for calibrating pressure measuring equipment. Units of measure are field-selectable and include bar, millibar, Pascal, inches of water or mercury, and millimeters of mercury.

The unit operates on 11-32 v dc for in-process applications or can be ordered as a portable, battery-powered calibrator. This full-featured sensor includes on/off and autooff capability, and front panel controls for zero, clear, and high or low recall functions.

The high/low pressure capture has a field-adjustable update rate of 3-10 times/sec. Units are made from stainless steel and use reliable sensor technology to deliver long-lasting, high accuracy performance, the company says. NEMA 4 construction provides EMI arid RFI protection.

The new Micropilot S radar level gauge is designed for high accuracy in custody transfer and inventory and storage uses.

It uses pulsed time-of-flight technology instead of the frequency modulated continuous wave principle. The new generation radar level gauge requires no maintenance.

With an accuracy of plus or minus 1 mm, the gauge helps ensure precise measurement for custody transfer and inventory and storage applications. Process conditions such as temperature, pressure, and vapor layers do not affect the measurement.

Here's the SRM6200E, a license free, wireless Ethernet radio modem. A complete data communications solution, the modem is suited for systems where cable installation is difficult or cost prohibitive. The modem is a suitable choice for SCADA applications, including water or waste water and oil and gas pipeline communications. This wireless alternative uses MAC layer bridging for true protocol transparency and fully supports TCP-IP-based protocols up to 15 miles away, with line-of-sight. The SRM6200E provides remote PLC programming and diagnostics, and wireless connectivity between corporate IS and control.

The modem has maximum data reliability-even in harsh environments-the firm points out. Interface options include 10Base-T (UTP) and 10Base-FL (fiber) interface to the Ethernet device.

Two new lines of gas dryers are designed to remove moisture in pipelines and at points of pressure reduction. The units help prevent freeze-ups and protect instruments and equipment against fouling and corrosion.

Dryers remove moisture vapor and mists from supply lines. This prevents ice formation in pipelines.

Dryers remove liquid water and water vapor and protect meters, regulators, valves, compressors, and instruments against fouling and corrosion.

Both lines feature rugged construction and simple, reliable operation.

A variety of desiccants is available to meet various inlet conditions and system requirements.
