PRODUCTS NON-CONTACT MEASUREMENT & INSPECTION PRECISE ROTARY POSITION SENSORS 3D MEASUREMENT SOLUTION
A new family of high-performance multi-turn non-contacting rotary position sensors has been introduced by TT Electronics. The MagnePot 8150 Series is designed to operate reliably over a minimum of 10 million shaft rotations with no signal output degradation. It combines the latest in Hall Effect non-contacting sensing technology and high-performance internal bearing design, resulting in a rotary position sensor with exceptional performance reliability, the company explains. The sensing technology also facilitates clean, ratiometric absolute position outputs across multiple turns without sliding contact noise. Units are available in a choice of three, five or ten turns, each powered via a 5VDC supply voltage. Additional features include a ratiometric output range from 4% to 96% of supply with a 12mA maximum current rating; ±0.50% independent linearity as standard, with optional improvement to ±0.25%;
and a standard operating temperature range of -40˚C to +125˚C. Device options include alternative output voltages, servo mounts, non-linear outputs, IP50 or IP66 ingress protection, and severe environment versions. Severe service models further incorporate sealed shafts and rear lids. The sensors are suitable for high-
reliability markets like industrial, medical and aviation/aerospace, with applications including industrial joystick controls; factory and laboratory automation; advanced manufacturing; robotic positioning; motion control feedback; medical diagnostic equipment positioning; aircraft
flight and panel controls; and vision system positioning feedback.

New from Imetrum is the 3D Precision Displacement Tracker (PDT), a precise non-contact 3D measurement system. The 3D PDT uses
pre-calibrated stereoscopic video cameras, combined with the company’s patented Video Gauge software, to deliver precise non-contact measurements on any point that can be seen within the image. According to the company, it eliminates the need to build frames for displacement sensors, bond strain gauges, run cabling or get too close to ‘hot’ objects,
saving time and improving the safety of test environments. The PDT is said to slash setup times and provides richer data sets, without compromising measurement resolution or sampling speed. Pre-launch product demonstrations at universities and motorsport companies have already led to several system orders and engineers working with composite materials and aerospace alloys have made comments such as: “We’re seeing things we couldn’t measure before”; and it “Cut our setup time from three days to half a day”.
Imetrum THERMAL CAMERA FOR HIGH-SPEED APPLICATIONS
Aimed at high-speed science applications, the FLIR X6900sc is said by the company to be the world’s fastest 640 x 512 pixel resolution thermal camera. It can record 1000 fps at full resolution onto its RAM for up to 26 seconds. Whether measuring temperatures on fast moving objects or characterising the thermal transient of objects as they heat up, the camera offers the rapid frame speed, high resolution, and thermal sensitivity required to virtually stop motion, enabling accurate temperature readings, and recording of gradients across the entire frame. True high speed infrared imaging requires fast integration times – down to
just microseconds – as well as the ability to capture data at 29,000 frames per second. The next generation infrared detector on the FLIR X6900sc makes it possible to record high speed data with the full 640 x 512 window, meaning
researchers can perform dynamic analysis of jet engine turbine blades, supersonic projectiles, explosions and more, without losing areas of the frame to windowing. Additional features include advanced triggering and synchronization, a secure solid state storage drive, and four-position motorized filter wheel.

Robust, non-contact, displacement measurement sensors from Micro-Epsilon are solving measurement applications for a number of key UK-based powertrain developments. One example is the turboSPEED DZ140, a turbocharger speed and temperature sensor system which is being used by automotive suppliers for a variety of applications. Features of the compact sensor system include a
miniaturised controller and the ability to measure both aluminium and titanium blades. It operates on the eddy current non-contact measuring principle and so is resistant to oil and dirt. As well as being able to measure the rotational speed of a turbocharger, the DZ140 can measure the temperature of the sensor head/tip, and enables measurements on blades with spacing of up to 2.2mm, at speeds of 200rpm up to 400,000rpm. The sensors offer a high ambient operating temperature of up to 285˚C. In another application, an engine coolant pump
on a high performance sports car kept failing and it was discovered that the carbon seal on the pump was leaking – but the actual seal failures were varying dramatically. It was discovered that the spring-loaded carbon ring seal was dynamically unstable under some conditions in service, allowing coolant to pass through. A sensor

was needed that would be capable of measuring the movement and alignment of the carbon seal. With very limited space to measure the static
seal, two 2mm diameter EU-05 eddy current displacement sensors were mounted at 90˚ to one another, which enabled the customer to get close to the static seal to measure its radial displacement and see exactly when the amplitude of the oscillations was highest. The sensor was also used to measure the radial and axial displacement of the pump shaft pulley. Non-contact laser displacement and inductive sensors are also being used to measure valve lift movement on a variety of engines, from standard push rod engines to more complex high performance motorsport engines.
