Sensors & magnetics

Our high performance magnetometers for navigation systems can be integrated platforms. We can also provide the electronic circuitry which will enable integration between the navigation system and flight management system.

During testing and calibration of the fluxgate, correction terms are derived to enable the mechanical misalignment, scale factor and offset terms to be corrected. We can supply these terms to enable error correction in software after digitization of the magnetometer outputs.

Magnetometer outputs can be converted to the magnetic field levels using the data supplied in the form of a correction matrix and three offset voltages.

Our range of 3-axis magnetometers have been designed to provide high precision vector measurement of the ambient magnetic field and are widely utilised in Attitude and Heading Reference Systems (AHRS).

We produce a range of magnetic sensors, all of which utilise similar Fluxgate Elements and associated circuitry. The variations accommodate alternative packaging options with different levels of environmental and EMC protection, qualification and different power supply and output voltage configurations.

Our Fluxgate Elements are extremely stable over time, and its temperature variations are able to handle typical shock and vibration levels. Error terms in our Analogue Output Products are corrected during manufacture using potentiometers or select on test resistors.

Software correction is used for our Digital Output Products.

Typical applications: spacecraft, remotely piloted air vehicles, target vehicles, down borehole measurement tools, harbour defence and surveillance and towed arrays.

We have designed and built bespoke magnetic test facilities in order to calibrate and test our high performance magnetic sensors.

We have a number of facilities to accommodate the throughput of magnetometers which reflect different test requirements. Each test facility is located on land that has been magnetically surveyed and had any local anomalies removed. The facilities contain bespoke equipment produced by us for each specific application.

High performance magnetometers are utilized to measure and cancel the Earth’s magnetic field (and variations), and to verify correct operation and calibration of the facility. Calibration is traceable to national standards.

Our multi-influence Measurement of Underwater Signature (MUWS) sensor solutions provide mission-critical high performance vessel underwater signatures. They are fully proven and in service worldwide.

Our sensor platforms have been designed and developed to accommodate all types of sea bed conditions. They can be permanently fixed to the sea bed or installed on purpose-built mounting platforms where a rapid “deploy and recover” system is demanded.

Our multi-influence MUWS sensors are available as 3-Axis Magnetic (Static and Alternating) and 3-Axis Electric (Static and Alternating) and can be configured to meet customer-specific pressure, acoustic and seismic requirements.

Our EOD Magnetic Test Set has been designed to check items of equipment for magnetic cleanliness to a predetermined safe level. Examples of equipment may include diver clothing, special tools, general materials and clearance equipment.

The EOD magnetic test set is fully man portable and is supplied in a robust, environmentally sealed, lightweight container. The unit is powered by internal batteries, can be setup for operation quickly and is simple to use.

The portability of the EOD Magnetic Test Set allows the clearance diver to check any article of equipment immediately prior to operations.

The EOD Magnetic Test Set has been in service with all three UK military Forces and is also operated by other defence forces around the word. Its full operational value has been proven in recent international conflicts.

We design and manufacture complete magnetic systems and the components used in those systems. We leverage the design of our components in order to produce optimal performance at the system level.

Our magnetic components are military-grade, and are often the preferred choice for applications in defence, aerospace, medical, telecommunication, and industrial equipment.

We manufacture advanced sensors and control devices for aircraft. Our units are designed for a particular segment of an avionics system and are customized to solve a unique problem. 

Our highly efficient controllers can be configured for any input voltage (AC or DC), with any output voltage.

The battery monitoring system (BMS) has been specifically designed for use on military vehicles. Based on patented technology that incorporates a real-time complex algorithm, the BMS simultaneously measures conductance, voltage, current, temperature and time to provide a highly reliable and accurate measurement of the state of health of a vehicle's batteries. The BMS provides the vehicle crew with accurate real-time battery health data. Technological advances in electronic equipment installed in modern military vehicles have led to increased demand on the vehicle battery bank. Historically, little or no attention has been paid to the condition of the batteries until a failure occurs.
