Technology Showcase: Instrumentation & Control
EP Editorial Staff | August 19, 2013
A new book, The Engineer’s Guide to Industrial Temperature Measurement, is now available from Emerson. According to the company, this new, free “go-to” resource can be ordered as a printed book, viewed online or downloaded as a PDF. Produced to help engineers, designers, operators and technicians understand and implement temperature-measurement technology, it’s packed full of useable information including, among other things, the basics of temperature measurement; conversion tables; maintenance and calibration practices; and proven results/application examples. Answers to 30 common challenges in a variety of industries and applications from Emerson engineers, sections on Rosemount Temperature Products, Reference Materials and Documentation are also included, as is a glossary with definitions specifically related to the temperature industry. According to the company, development of this comprehensive guide was a joint effort of Emerson and its colleagues, customers and companies, including The Dow Chemical Company, Hindustan Petroleum Corp. Ltd., BorsodChem, Beamex Inc and BiLFINGER.

Enhanced-Control, Air-Operated Diaphragm Pumps
Ingersoll Rand’s newly launched range of ARO electronic interface, air-operated diaphragm pumps expands the company’s existing EXP and Compact Series portfolios with installed sensors and controls. According to the company, these products offer accurate, electronically controlled dosing for paint-formulation, automated-car-wash, commercial-laundry, chemical-processing and printing applications. The units can be configured to order with solenoid actuation and several feedback sensors for enhanced safety and control, e.g., leak detection and stroke monitoring. ATEX configurations and multiple voltage options are available to help meet the compliance and electrical requirements of certain applications. ARO electronic interface pumps are offered in a wide range of port sizes: 3/8”, ½” and ¾” Compact Series pumps; and 1”, 1.5”, 2” and 3” EXP Series pumps.
Economical, Intrinsically Safe, Two-Wire Magmeters
Endress+Hauser has released the Proline Promag 200 electromagnetic flow meter, a two-wire magmeter that offers the same measuring performance as four-wire magmeters. The Promag H200 is available in line sizes from 1/12” to 1”, and the Promag P200 is available in line sizes from 1/2” to 8” for measuring the flow rates of conductive fluids with an accuracy of ±0.5% of range and repeatability of ±0.2% of range. Both operate in process temperatures from -40 to 304 F. Connections include welded, threaded, hygienic and flanged versions that meet
EN/DIN PN 16-40, ASME B16.5 Cl 150, Cl 300 and JIS 10K and 20K process connection pressure ratings. According to the manufacturer, installation is simpler and less costly than a four-wire device because a separate power source isn’t required. Since these units are intrinsically safe, no seals or external enclosures are required for installations in hazardous areas.
Lean Connectivity Solutions Transform Panel Wiring
According to Eaton, its SmartWire-DT panel wiring system is designed to dramatically reduce assembly and commissioning time, allowing an installer to duplicate panels seven to ten times faster than before. Because it replaces numerous wires used to connect motor control components with a single cable, the company says the SmartWire-DT system can transform how control panels are built. Using an eight-pole, flat cable located in the control cabinet, this wiring solution reduces panel complexity by connecting to starters, contactors, pushbuttons, pilot lights, selector switches, relays and I/O modules. SmartWire-DT is available with EtherNet/IP and ModBus TCP, in addition to PROFIBUS-DP and CANopen. This added flexibility allows the SmartWire-DT system to more easily integrate the user’s preferred industrial network and third-party PLCs.
Solar-Powered Industrial Thermometer
Palmer Instruments has added a new solar-powered digital industrial thermometer to its line of temperature-measurement solutions. Featuring a ½”-high LCD screen, it is, according to the company, well-suited for users who prefer the readability of a digital thermometer. A built-in solar cell means the product’s batteries never need replacing. Even a flashlight is enough to power the device. Completely mercury-free, these solar-powered units can be safely mounted in a variety of environments. Their adjustable-angle fittings rotate a full 180°, allowing for installation at the best possible viewing angle in a plant area. Models that incorporate 4-20 mA-transmitter capabilities for connection to a remotely installed controllers or recorders are also available.
