Compared with the earlier version, the new technology offers digital resolution more than four times as high and unsurpassed dynamic range; faster digitization rates; an order-of-magnitude increase in oversampling speed and in digital quadrature detection; more than an order-of-magnitude increase in digital filtering bandwidth; and a single receiver for liquids and solids, and for imaging applications. The 2G-DR technology will be beneficial for demanding NMR experiments in solid-state research, synthetic polymer and trace analysis, and magnetic resonance imaging and structural biology, especially when used with the company’s highest sensitivity CryoProbes.

It combines the strengths of the boundary element and finite element methods for faster and more accurate solutions. It also features quadratic and angular periodic finite elements. As with earlier versions, MAGNETO 6.2 offers advanced modeling techniques that link directly to parametric-based CAD packages for the true geometric representation of complex shapes. The program is used for applications such as clutches, solenoids, motors, sensors, transformers, loudspeakers, magnetic shielding, circuit breakers, and fuel injectors. The software’s calculations include force, torque, flux linkage, and inductance.

The overall dimensions of the cryostat are 258 mm × 224 mm × 540 mm. The system uses a 1-kW single-phase air-cooled compressor to provde 4.2 K with a cooling power of 0.1 W and 3 W at 50 K; it can be operated at temperatures below 4.2 K. A uniformity of 5 ppm over a 10-mm-diam-eter spherical volume has made it possible to use the magnet for ESR (electron spin resonance) and low-field NMR experiments. It is thought to be the smallest superconducting NMR magnet yet built. The magnet has its current set at 30 A and can be operated with the current permanently in the leads. The heat load from the leads is about 1.5 W, or in persistent mode, the current decays at 10−5 per hour.

The device provides absolute angle information in a digital format and targets motion-sensing applications that require a resolution below 0.1° of angle. The user can continuously access a serial digital output and pulse-width-modulated (PWM) output at the same time. The angular-position information is in the form of a serial data stream and as a PWM signal with a resolution of 4096 positions per revolution. The model AS5045 has zero-position setting and diagnostic features that are both user-programmable, and the option to cascade several devices in a daisy-chain configuration.

Fully digital signal processing supports two channels that can be used as a 2:1 multiplexer or for simultaneous measurements at up to 60 measurements per second. The new magnetometer features a resolution of ±0.01 ppm, a relative accuracy of better than ±0.1 ppm, and automatic tracking over 100% of the probe range at a maximum rate of 4% per second. Its trigger input allows precise synchronization, and reference frequency and NMR signal outputs allow access to analog signals.

The FL7004 laser probe is exceptionally small, with a sphere that measures slightly more than one inch. Its unique antenna design performs better in the presence of harmonic distortion and allows for better isotropic response, free from spikes and glitches. Noise reduction and temperature compensation enable extremely accurate low-field readings, down to 0.5 V/m or better. The six field probes cover the frequency range from 100 kHz to 60 GHz. One of the probes (model FP7050) can read radar pulses. The field monitor works with either laser or battery-powered probes.

The AHRS500GA is a truly independent device, meaning that there is no need for Air Data or GPS inputs. Its highly reliable inertial system operates with static and dynamic accuracy that is reportedly superior to spinning-mass vertical and directional gyros. The CMR500GA, a three-axis strap-down magnetic-field measurement system, uses high-resolution fluxgate sensors and outputs data for three axes of magnetic-field and built-in test status.

It consists of a quadruple Hall sensor array that has been optimized for the magnetic measurement of angles of rotation. The user can choose from 26 operational modes for evaluating the angular position of the rotary magnet mounted over the chip. The integrated signal-conditioning unit provides a differential sine/cosine signal at the output. The sensor generates one sine cycle for each full rotation of the magnet, which enables the angle to be clearly determined with the aid of an 8-bit sine-to-digital converter. An incremental interface provides an output in a number of selectable resolutions. The maximum resolution of 8 bits is maintained up to rotations of 60 000 rpm. Used with a permanent magnet, the iC-MA can act as an encoder system with an integrated magnetic scanning feature.
