product
Electronic Control Units
Self-contained engine management system and data logger for race engines up to eight cylinders. The unit is complete with integrated ignition and injection drivers and so needs no external units to run an engine.

product
Accelerometers
The unit is based on micro machined MEMS technology. The unit contains a 35g sensing element. The element is scaled to optimise the resolution to suit the g range of interest. An internal amplifier provides an output between 0 and 5 volts. The on board microcontroller and temperature sensor are used for offset drift compensation. This unit can be re-calibrated at the factory.

Temperature Sensors
Temperature sensors have a well-defined relationship between electrical resistance and temperature, allowing them to measure temperature precisely. The sensor body is made of a thermally conductive material and is as small as possible to produce a rugged device which gives an accurate measurement of temperature with a fast response.

Linear Hall Sensor
The output of a hall effect sensor is a voltage which changes in proportion to the shaft extension. A constant voltage is required across the supply and ground wires of the sensor. The sensor consists of a Hall Effect element, and a shaft which houses a magnet. When the position of the sensor changes relative to the shaft, the change in magnetic field in the sensor results in a change in output voltage.

CDI Ignition Coil
An on-plug coil for use with Capacitive Discharge Ignition (CDI). Design and manufacture is in-house, so we can make the coil to suit your specific application. The information given here is for a typical coil. Many of the parameters can be tailored to a particular installation.

product
Tyre Pressure and Infra-Red Sensors
The system consists of a powered pressure and temperature sensor with transmitter fitted to a wheel rim. This sends pressure and temperature data over an RF link to a compact receiver on the car. Sampling rates increase automatically when either a change in pressure is detected or when wheel inertia is detected. The system stops transmitting below a threshold pressure to preserve battery life. The receiver sends data to the car control via CAN.

Ignition Driver Units
A compact inductive ignition drive unit which drives two banks of five ignition coils. The drivers are controlled via direct logic signals from a host ECU and provide fire-by-fire diagnostics back to that unit via CAN. The coils can be run at voltages up to 30V with this unit in order to minimize dwell times for optimum response.

Calibration Software
System Monitor is a software package for configuring and tuning automotive control systems. It has built-in support for motor sport systems and can be tailored to support third party control units.System Monitor not only allows you to tune data for your program versions, but also manages those versions on disk, allowing them to be located quickly for programming or modification

Temperature Sensors
The infrared sensor measures temperature at a distance without contacting the target. The integrated infrared module senses the thermal radiation emitted by objects on a 16 x 4 array of sensing points, for measuring the temperature distribution across a surface. These 64 measurement pixels are transmitted via CAN to the host controller or data logging device. The sensor is available in both 35 and 60 field of view options to suit a variety of installations. A software package is provided for viewing live temperature data from the array.

Pressure Sensors
The output voltage of this sensor changes with absolute pressure. An internal amplifier creates a single-ended, amplified output in the 0 to 5 Volt range, so the sensor can be connected directly to most control units. The body and diaphragm are impervious to chemical attack by standard motorsport fluids.

Thermal Camera
The thermal camera allows real-time thermography with 100Hz frame rate via USB 2.0 interface. The camera is lightweight, compact and rugged (IP65). Measurement ranges of -20C to 100C, 0C to 250C, or 150C to 900C are selectable in software. Interchangeable lenses are available with 6x5, 23x17, 48x31 and 72x52 field of view.

Fluid Level Sensor
The output of the fluid level sensor is a voltage which changes in direct proportion to the level of fluid in the probe. The difference in permittivity between air and the fluid being measured changes the capacitance between the probe's two concentric tubes as the level changes. An RS232 connection to a PC allows the user to calibrate the fluid level and thermal drift compensation. The probe is factory replaceable, allowing the electronics to be re-used should the probe become damaged or if a new probe length is required.

Signal Conditioning
The output of an inductive (magnetic reluctance) speed sensor is an alternating voltage in which both the frequency and magnitude depend on target speed. The TTL Interface Adaptor converts this voltage into a TTL logic signal whose frequency corresponds to tooth passing frequency. The magnitude of the output signal from the interface is independent of the tooth passing speed.

product
Rotary Hall Effect Sensor
The output of the Rotary Hall-effect sensor is a voltage which changes in direct proportion to the shaft angle. The sensor is non-contact, using Hall elements to determine the angle of a magnet. The magnet is either mounted in a shaft integral to the sensor or can be mounted externally to the sensor.
