Variohm Eurosensor has added high-performance EGT and tuning temperature sensors to its motorsport sensor range following a distribution agreement with US thermal measurement specialist Zip Sensors.

The agreement covers a selection of Type K sensors that are said to be reliable and durable for applications such as exhaust gas monitoring and other critical thermal measurement tasks.

Zip Sensors supported the winner of the world land-speed records at the Texas Mile event in Goliad, Texas, in October 2010.

It supplied specialist EGT sensors and cylinder head temperature sensors to the Wild Bros Racing Team and winning rider Bill Warner for the turbocharged, 1,299cc Suzuki Hayabusa, which reached a world record speed of 278.6mph (448.36km/h).

This competition for the world’s fastest street bike followed similar successes with consistent track records in standing mile events across the US during 2010.

With just a few attempts allowed and with meticulous detail required for the bike setup, the events consisted of a standing start with a mile of track to reach terminal velocity and just half a mile to come to a controlled standstill.

Such land-speed record events are known for extreme environments with very high operational temperatures and excessive vibration for long periods of test and track use.

The 650hp machine included four exhaust gas temperature sensors that were built to the Wild Bros Racing Team’s specification with Type K calibration, exposed tip sensing junction, high-temperature lead wire and Type K miniature connectors.

With all-stainless-steel construction and high-tech ceramic components used for insulation in the area of the lead wire and thermocouple junction, the sensors featured brazed rather than crimped construction to ensure reliability in critical stress areas.

Two sensors were customised with precisely modified bend radii to fit within the confined area around the turbo charger.

The cylinder head sensors, also with Type K calibration, were hand-formed for interfacing the end of the thermocouple to accommodate existing cylinder head bolts.

Zip Sensors also offers a complete range of off-the-shelf Type K sensors for demanding temperature measurement applications across all areas of motorsports.

Several standard configurations are available that work well with all types of racing, from drag racing to motorcycle to Formula 1 as well as diesel applications.

Standard versions help to shorten lead times for customers and make the quotation process quick and straightforward.

Aimed at users from the serious enthusiast to professional race teams, the standard sensors include the entry-level Sportsmen’s Series, with exposed tip sensing in stainless steel and Teflon-insulated conductors, to the Pro Series, featuring grounded enclosed tip sensing in Inconel stainless steel with optional ceramic fibre insulation with stainless protective braid.

Essentially covering temperatures from -100C to +1,300C, the complete range includes EGT variants for diesel, petrol, methanol and nitro exhausts with Type K calibration and complete compatibility with data loggers.

Thermal sensors specifically for use on motorcycles and dynamometers are also available.

The new Zip Sensor range is a part of a portfolio of specialist sensors and transducers that Variohm Eurosensor supplies across the motorsport industry, including Formula 1, A1GP, WTCC, GP2, Champ, Nascar, ALMS and Superbike.

The complete range includes pressure and temperature sensor solutions for fuel, oil, coolant and brakes as well as force, torque and position measurement sensors for suspension travel, throttle and gearbox.

Laser and infrared technologies are also supplied for ride-height position and tyre condition.
