Stationary ship will be treated and ranged by magnetic deperming range in a cage System for the demagnetization of naval ships and subsequent magnetic surveying on a magnetic demagnetization and surveying equipment installed within a cage type frame, with the special feature that the ship is stationary during the entire treatment process similar to the earth magnetic simulator of German Navy. Treatment and magnetic measurement of Navy vessels in combination with time optimzed and area economy lead to a range that combines the advantages of ODMR and HDMR, where all system entities are installed on a frame around the vessel undergoing ranging and treating. Above sketch shwos the ODMR combining simulation and deperming coil system integrated on a cage type building, which can be installed on any harbour or Navy area. Pricing may vary depending on cable length, available power supply and required magnetic field.

One single MiniFEB (Front End Board) allows the operation of 3 sensors parallel. The MiniFEB has an TCP/IP output protocol and can be used for many channel systems by combining with a switch. A backplane can be used for power supply and synchronisation of all MiniFEB boards. Pricing may vary depending on requested cable length and available power source.

The MD900 is an inductive metal detector for use in garbage sorting. It consists of a high-frequency field generator and a series of probes running transversely to the treadmill, which analyzes the product stream in a location-specific and location-resolved manner. The data for the opening and closing of the valves, which are transmitted in real time via an SPI interface to the valve control in the blowout unit, are calculated. Operation is via an Ethernet interface. All data for configuration during operation (operating mode, sorting program and other parameters) are transmitted via the Modbus / UDP protocol. For updates and error analysis, an independent TCP/IP interface is available. The sensor is connected via 2 connection cables to the blow-out unit.

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.

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

The analogue to digital converter series of type „DX“ are specially designed for a large dynamic range and high stability, which makes them suitable for almost all applications.These ADC’s have internal digital calibrations resulting in highly significant signal output. Due to this digital signal processing, all signals have the identical transfer function which allows for high precise post-processing of the data. Highlights - Low power consumption - Very low noise, large dynamic range and high linearity - Digital temperature compensation minimizes drifts - Sensor output digitally error-corrected with respect to scaling and offset - Small size and lightweight - Single coaxial cable for power and data introduces minimal magnetic signature

High sensitive 24/7 observation and monitoring system, which allows an optimized responding time against any unwanted asymmetric threats. With the harbour and coast protection system of STL, the Navy will have the general capability to detect unknown threats by passive measurement of the signals of an invader. The observation can be conducted for surface and subsurface surveillance. The advantage of the passive detection is that an invader will not recognize he is under monitoring and observation. This increases the moment of surprise and is a big advantage for the naval staff.All this is made possible through an optimal use of available high technologies. Our 3rd generation system is based on STL‘s high resolution data acquisition, highly sensitive preamplifiers in combination with UEP electrodes, very low noise magnetic field sensors, acoustic sensors with highest accuracy, together with state-of-the-art underwater and computer technology

The digital magnetometers of the DM Series are based on STL’s unrivalled high resolution ADC technology with 32 bit resolution and 26 bit dynamic range. The magnetometers use fluxgates as their magnetic sensitive elements and have integrated DXS. As a result of consequent digital signal processing, our magnetometers are quasi ideal sensors with digitally corrected geometry and temperature errors. The DM Series provides a measurement range of up to 1 mT, with an ultra precise digitization taking place immediately after the sensor output. All magnetometers measure the 3 orthogonal field components with a maximum sample rate of 10 kHz and offer very low intrinsic noise from 60 pT/√Hz @ 1 Hz down to 6 pT/√Hz @ 1 Hz. The software also offers the total field as an extra virtual channel. Typical error sources like axes misalignment, scaling, offset and phase errors are eliminated to the greatest possible extent due to its consequent digital signal conditioning strategy.

System for the demagnetization of naval ships and subsequent magnetic surveying on a magnetic demagnetization and surveying equipment installed on a pier, with the special feature that the ship is stationary during the entire treatment process. Treatment and magnetic measurement of Navy vessels in combination with low cost and area economy lead to a range that combines the advantages of ODMR and CDMR, where all system entities are installed vertically on a low-level magnetic jetty or pier. STL has developed this idea becoming the Half-Space Deperming Range (HDMR) providing cost and time effective deperming and measurement processes for Navy vessels with an optimal benefit-cost-ratio. Above sketch shwos the HDMR combining simulation and deperming coil system integrated on an existing jetty.

The ODMR (Overrun Deperming and Measurement Range System) is a system dedicated to reduce the magnetic signature of ferromagnetic surface vessels and submarines. It allows a magnetic treatment to control the permanent magnetic signature of the ships in such a way that the ships magnetic signature is minimized. The deperming efficiency depends on the individual class of vessel undergoing treatment, the magnetic behaviour of the steel used, the building process and the magnetic history of the vessel and the operational area with respect to its vertical magnetic field component. The fields of the ODMR are sufficient large to allow a deperming and ranging for all missions required. The ODMR can be designed for all kind of surface vessels and submarines independing of the displacement with maximum length of upto 250 m length, with the dedicated beam depth.
