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.

Thermocouple
This sensor uses a K-type Chromel/Alumel thermocouple and is intended for use in high-temperature, high-vibration environments. Control units and data loggers support K-type thermocouples. The sensor is short and compact to minimise its susceptibility to vibration.

Microwave Transmitter
LTX-310B
LTX-310B is a self-contained microwave transmitter for use with the LRX-310B receiver. The output is pulse modulated to identify one of 36 channels arranged in six groups of six. The group is set at the factory and you can select one of the six channels in that group from an external rotary switch.

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.

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.

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.

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.

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.

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.

Sport Sensor Range
DHE (Differential Hall Effect) sensors give an output when subjected to a changing magnetic field. The field is set up by a magnet inside the sensor body and changes when ferromagnetic teeth are passed beneath the sensor (no magnets are required in the target). To improve noise resistance, the sensor has two Hall effect elements and only responds to changes in magnetic field strength corresponding to tooth passing frequencies above 15Hz. As each tooth passes the sensor, the digital state of the output changes

Torque Systems
The Drive Plate Torque System uses a low power radio link to transfer digitised strain measurements from a rotating wheel hub to a stationary antenna mounted nearby. The signals are passed to a receiver where they are decoded and output as CAN bus messages and analogue outputs.

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.
