ZeroK specify Variohm VLP position sensor for electric kart throttle control

ZeroK is an all-electric racing kart power system, the brainchild of designer and driver James Davies. During 2015 various iterations of the kart have been built and tested with the aim that ZeroK will be introduced as a competition class of its own. Competing against other ZeroK teams and potentially providing young drivers a new route to Formula E – and of course thrilling karting enthusiasts in the UK and further afield. Being electric, the kart is almost silent with enormous torque for swift, lag free acceleration, a top speed of over 70mph, and 0-60mph in around 4.5 seconds. Recent power system developments have included a new supercharged controller, heavier cables and new motor/electrics cooling that delivers up to 40hp with a short-term potential of 80hp and a larger capacity hot swappable battery. To allow James Davies to finely control all this power, the ZeroK team turned to Variohm EuroSensor and specified its motorsports proven VLP series linear position sensor for the kart’s throttle pedal control. With its dual seal design the VLP provides extended reliability for the demanding race track conditions the kart needs to endure. With essentially infinite resolution and 0.1% linearity, its repeatable and consistent performance translates into optimal throttle control. The sensor features a conductive plastic resistance element and multi-fingered precious metal wipers in an elastomer damped mechanism to ensure smooth and uninterrupted contact – even under the most arduous physical and environmental conditions. It certainly meets with the driver’s approval. “The VLP helps keeps the power smooth through all speeds and conditions on the track,” says Chris McCarthy Test Driver for Karting Magazine. The...

Rotary actuator and sensor can be installed in seconds

Festo, the leading supplier of automation equipment, has launched a new semi-rotary vane drive – the DRVS – with a unique new sensor solution which can be fitted in seconds. This enables machine builders and engineers to save valuable installation time and associated costs, and it provides excellent performance at an attractive price. The drive has a simple and compact lightweight design and delivers high torque ratings of up to 20Nm. It is powerful even in harsh environments and has an infinitely adjustable swivel angle which means that it gives increased flexibility to the user for up to 90, 180 or 270°. When combined with the unique SRBS sensor detecting the rotation is made easy. The SRBS is a closed and encapsulated unit that can be quickly assembled and screwed into place, which means it is exceptionally easy to install. Switching points can also be taught electronically by simply pressing a button. As such it provides innovative sensing without the need for mechanical adjustment and manually searching for switching points, thus reducing set-up time. Sensing is performed magnetically and without contact, and as a result, offers a long service life and reliable operation. The actuator and sensing solution is ideal for simpler flap, divert, escapement type applications in light assembly and packing machines. “Fitting semi-rotary drives with sensors has never been so easy, reliable, uncomplicated and error-free as they have with the DRVS and SRBS,” says Steve Sands, product manager at Festo. “The sensor offers simple and reliable operation using just one push-button, and when combined with the drives provide simple rotary motions that tell you where they are...

Sensors meet the needs of harsh, demanding automotive applications

Chris Jones, Managing Director at Micro-Epsilon UK, discusses some of the more challenging automotive applications for non-contact displacement measurement and infrared temperature sensors. With increasing pressure on vehicle manufacturers to downsize engine components, minimise the weight of onboard systems and therefore reduce fuel consumption and vehicle emissions, the requirement for extremely compact, high performance sensors is now critical, especially if installation space is also restricted. This is also true for integration – both in terms of electronics and building more intelligence into the sensor, without the need for any bulky, separate controllers. This means that displacement and laser profile sensors are more frequently required to perform signal conditioning directly in the sensor, therefore reducing component count, whilst offering faster measurement speeds. Extensive range of sensors for automotive applications Micro-Epsilon has been developing non-contact displacement measurement and infrared temperature sensors for automotive applications for more than 45 years. These sensors are used in automotive R&D, test cells, production and for on-vehicle testing in almost every conceivable area of a vehicle. Applications range from eddy current sensors for measuring turbocharger speeds, piston ring movement, cylinder head lubrication gap and crankshaft bearing gap; inductive sensors for measuring engine valve lift; draw wire sensors for measuring suspension spring/damper movements; laser sensors for measuring brake disc deformation, vehicle ride height, monitoring the integrity of welds and adhesive beads during assembly or production and for the inspection of tyres for bulges or dents; and non-contact temperature sensors and thermal imaging cameras for measuring the temperature of on-vehicle components. For more than 15 years, Micro-Epsilon has developed specific sensor variants for turbocharger speed measurement, enabling turbocharger...
