ADVERTORIAL TECHNOLOGY IN ACTION Miniature load cell for audio equipment R RCT1000 Coriolis Flow


Meter from Badger Meter R


CT1000 meters are especially suited to the precise measurement of high viscosity fluids, aggressive media


and contaminated fluids as well as high density gases, whilst maintaining a wide turndown ratio. Typical applications for these mass flow meters will include filling or dosing oils, solvents and chemicals and measuring adhesives or binding materials, coatings and hardeners, dyes, vitamins and other additives. Renowned for their outstanding accuracy and versatility in measuring challenging flow applications, Coriolis principle flow meters have been employed in a wide variety of industries and applications. Coriolis flow meters are true multi-variable instruments, which means that they provide simultaneous measurement of mass flow, density, temperature and volume flow. A valuable feature of this design is the lack of internal


moving parts, enabling the flow meter to experience little or no mechanical wear, resulting in a long operational life expectancy.

ega began designing and manufacturing audio equipment in 1973 and today, thanks to its obsession with innovation and the resurgence of interest for vinyl, is now the UK’s largest manufacturer of high-end turntables.


Rega doesn’t just make


excellent turntables, its range includes amplifiers, loudspeakers, CD players, cartridges and tone arms as well as many accessories that enhance the hi-fi experience for the discerning listener. Demonstrating its continuing role as a technological innovator, Rega will soon be launching a new accessory – a weighing scale that precisely measures stylus tracking force. With tone arm set-up critical to sound performance as well as stylus and record condition, Rega’s new Atlas Tracking Force Scale will confirm tone arm adjustment to 1/100th of a gram with a working range of 3.5 to 5 gm in a simple in-situ process. As an integral component for the scale, Rega chose the Zemic Q70 series miniature load cell, supplied and fully supported in the UK by Variohm EuroSensor. Having identified that an accurate way to measure


tracking force was desirable for the high-end audio market, Rega set out to design a scale that would be affordable and be able to be offered alongside the majority of its turntable range. Rega design engineer, Ashton Wagner explains how the project developed,


"We looked for a load cell with an accuracy to one


hundredth of a gram that would fully maintain that accuracy over its lifetime; we needed excellent durability and a scale that would not require calibration by the user." Budget constraints were also fully considered at the outset, "To meet our target costs the use of premium digital and analogue electronics were off the table. A microcontroller with an embedded commodity ADC was chosen which meant, that to achieve the accuracy we desired, we would have to use a high gain amplification circuit with little room for adjustment.

High Flow Volume/Filter Booster – 500% Highest Flow Reduces Costs B


filter boosters are SIL 3 third party certified to IEC 61508 Parts 1 & 2.


In applications where a fast response time on modulating service, in combination with a fast shutdown time (ESD), is required, the VBP also eliminates the need for an additional poppet or Quick Exhaust Valve to achieve the required closing speeds. This results in reduced material and labour costs and simplifies positioned set up and control. The range functions with a working pressure range of 2


to 10 bar g, with maximum inlet pressure of 20 bar g and operates at a working temperature of -55ºC to +180ºC. The common design format offers a choice of four main sizes with port threads of 1/4”, 3/8”, 1/2”, 3/4”, 1”, 11/2” and 2” NPT which allow for installation flexibility and easy hookup. The EQUAL internal porting and balanced forces allow identical fill and exhaust flow, making setup extremely simple and controllable. Amplification of any control logic can be achieved by


incorporating the volume booster with our 'AXIS' and modular system solutions. The pneumatically balanced design minimises the


impact of both downstream and upstream pressure variations allowing for improved control along with the block before bleed function. Captive Venting, ideally suited to arctic service applications and has been tested to -60°C.

ifolds patented unique volume and filter booster range in 316L stainless steel provides up to 500% higher flow than the market equivalents. By removing all elements from the main flow line, including, regulators and filters, the effective CV of the patented filter booster is multiplied, resulting in significantly reduced tubing sizes. Where safety is critical, Bifolds range of volume and
