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.

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.

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.

Data Loggers
The unit can acquire data from on-board interfaces at rates of up to 10 kilosamples per second, and from remote units via communications links. A high-performance on-board PowerPC microprocessor offering over 1000MIPS processing power hosts customer applications for real-time data analysis. Application code may be autocoded using our Graphical Development Environment (GDE) from Matlab/Simulink control modules. Data is logged to 2GB of on-board Flash memory and downloaded for analysis via a Gigabit Ethernet network connection.

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.

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.

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.

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.

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.

Speed Sensors
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.

product
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.
