Precision current loop calibrator saves time

The Comtest Group , Fluke’s authorisedTest andMeasurement Distributor for South and southernAfrica, has offer Fluke 709 and 709H mA loop calibrators, specifically designed to save time and produce high-quality results. These calibrators are built around

a user-friendly interface with a Quick-Set rotary encoder knob. This tool reduces the time it takes to measure, or source, current and power up a loop.The protective holster easily fits into a technician’s hand and the large backlit display is easy to read, even in dark, cramped worked areas.  The 709H adds HART communications and supports a select set of the HART universal and common practice commands. This makes the 709H unique as both an affordable, compact loop calibrator and powerful HART communication troubleshooting tool. In the communicator mode the user will be able to read basic device information, perform diagnostic tests, and trim the mA output on most HART enabled transmitters. In the past, this could only be done with a dedicated communicator, a high-end multifunction calibrator, or a laptop computer with HART modem. Fluke 709H will allow virtually any

technician to service and support HART de- vices.  In addition, the 709H offers: • Logging of HART data in the field. Once recorded by the 709H in the field, the 709H/ TRACK software can upload the HART configuration of up to (20) HART devices in your plant and output data in either (.csv) or (.txt) format.  • Data logged mA loop measurements and HART data can be recorded from a particular transmitter for trouble- shooting and loop tuning. The data log feature offers selectable capture with recording intervals of 1 to 60 seconds and a logging capacity of 9 800 records or 99 individual sessions. Each data sample contains the 709HmAmeasure- ment, all four process variables, and the standard status conditions. Enquiries:Tel. +27 (0) 10 959 1821 or email sales@comtest.co.za

Reliable software for multiple phase measurement Emerson Process Management introduces Micro Motion Advanced Phase Measurement (APM), a software option available on the Model 5700 Transmitter. The software solution helps improve measurement accuracy across diverse industries in challenging multi-phase applica- tions such as direct wellhead and separator net oil measurement in the oilfield and starch concentration for food and beverage plants. This multiple phase measurement solution provides insight into the complete flow stream, including oil, water, and gas, through an intuitive, local display. Leveraging Emerson’s years of experience in providing solutions for process upsets or intermittent two-phase flow, Advanced Phase Measurement provides continuous, real-time production data for oil, water and gas void fraction. “Advanced Phase Measurement was designed with production engineers in mind, providing insight into production trends with a single device to reduce capital and operating expenses,” said Kevin Borden, Product Manager. “You can track whether production is increasing or decreasing, allowing proactive management of changing field performance which ultimately equates to more dollars in your bottom line.” Advanced Phase Measurement has also proven useful for the life sciences and chemical industries, providing critical measurement insight to reduce waste, maintain product quality, and identify process upsets even in the presence of multiple phases.

Earthing and short-circuiting device with aluminium cable When using aluminium-cable earthing and short-circuiting devices instead of copper-cable for railway systems, switch- gear installations or overhead lines, the advantage of the weight-reduced cables becomes immediately evident. The new aluminium earthing and short-circuiting device (single-pole, 50mm² or 70mm²) from DEHNAfrica is consider- ably easier to transport and use than conventional devices. In the past, high copper prices led to material theft and damage, meaning that the new earthing and short-circuiting device with aluminium cables offers huge cost saving and conveni- ence potential. The new offering from DEHN Africa comes in a variety of different models, including an earth clamp for overhead contact lines and clamp for railway tracks with tommy bar; an earth clamp for overhead contact lines and clamp for rail- way tracks with ratchet; a universal clamp (T Pin Shaft) and universal clamp (Handle); a conductor clamp and universal clamp (Handle); ball head caps (Ø25 mm); a universal clamp (Handle) and clamp for railway tracks with tommy bar; a universal clamp (Handle) and clamp for railway tracks with ratchet; and with universal clamps (Handle) on both sides. Thus, earthing and short-circuiting kits can be fitted with the available clamps using diverse combinations to fit the required function.
