Measurement of magnetic and electrical signals with STL's unique 26 bit ADC's For measuring electric and magnetic fields the STL's unique 26 bit ADC pioneers works in an underwater system. In addition to deployment and recovery the chain configuration by a single cable used for power and data transmission uses three or more sensors platforms are fully connected to the base station. Environmental and pressure sensors use an ultra low noise isolation preamplifier, and the analogue sensor front end is formed by 3 pairs of UEP Carbon electrodes. The 26-bit analogue to digital converter is what the digital part is based on with a novel high end performance. Geometry compensated signal output through the consequent digital signal processing provides temperature. To achieve the software alignment the tilt sensors are used to achieve the precise settings with a pair of high resolution electric field vector components.

Our coil systems are specially designed to generate very large magnetic fields in 1 to 3 dimensions. Every system essentially consists of 2 units: The coil system and the current control system to set the coil currents. The systems can be used for calibration, to compensate external fields, to generate specific magnetic fields, magnetic gradients etc. Our specification scope ranges from: - Frequency ranges: DC to 4 MHz, - Field ranges: from a few microtesla to 200 millitesla - Homogenity ranges: 1%, also over large volumes with small coil sizes - Field stabilities up to a few ppm FS - Size range from a few cm to more than 200 m - Actively compensated for environmental changes or uncompensated (optional) - Generating both magnetic fields and magnetic gradients with or without compensation - Magnetic far field drop off: r-3 to r-11

STL offers the earth magnetic field simulator (EMFS) which can be used for worldwide simulation of the earth magnetic field. Earth Magnetic Field Simulators (EMFS) are typically being installed in a bay area or river estuary as well as artificial harbours. The EMFS System is used for calibration of the onboard degaussing system (OBDS) and Navy vessel's preparation for any operation missions and the dedicated simulation of the magnetic field in the area of mission. Quantity and type of used sensors, sensor array, software and coil system including power sources are always designed in respect of the specific requirements of the customer. STL can supply: - Complete sensor array - Data acquisition system - Control and evaluation software - coil cables and power sources Pricing may vary depending on the requested cable length, available power supply and required magnetic field.
