Temperature Elements for Flight-Critical Equipment

FCI Aerospace’s (San Marcos, CA) AS-TE Temperature Element Series sensors utilize precision resistance temperature detectors (RTDs) to provide superior accuracy, repeatability and long-life. The AS-TE sensors are typically designed with Platinum RTD or MIL-T-7990 Nickel RTD sensors. The Platinum RTDs are available in several Ro (ice point resistance) values and in either two-, three- or four-wire configurations to ensure optimal performance and system compatibility.

The AS-TE Series sensors are fully qualified to comply with high vibration, severe shock, and high acceleration environments and specifications. They have been tested to perform after exposure to more than 100,000 temperature cycles from -40 to +300°F (-40 to +150°C). The standard temperature measuring ranges are -80 to 450°F (-62 to 232°C) and high temperature elements are available up to 800°F (427°C).

Voice Coil Motor

The GVCM-051-127-01 Linear Voice Coil Motor is Moticont's (Van Nuys, CA) newest linear DC motor with internal shaft and bearing. The 3.75 in. (95.3 mm) stroke of the precision ground 0.236 (6.0 mm) diameter shaft with an internal thread, is guided by a long-life plain bearing that can allow side loads up to 1 lb (4.4 N). The housing and coil ends of the motor have threaded mounting holes for easy integration into existing and future applications. This brushless voice coil actuator features: high speed, high acceleration/deceleration, zero backlash, high accuracy, high repeatability, and a high force to size ratio of 5.0 lbs (22.2 N) continuous force and 15.8lb (70.3N) of peak force in either direction, in a housing measuring just 2.00 in. (50.8 mm) dia. × 5.00 in. (127.0 mm) long.

Military-Grade Network Switch

MilSource (El Segundo, CA) announced the availability of Techaya’s (Akiva, Israel) MILTECH 24FO, a compact fiber optic enabled Ethernet switch offering a dense 24 ports in an approximate 8" × 4" × 2" footprint. The fully managed switch is ideal for radar installations, EO sensor suites, persistent wide area surveillance, and signal intelligence applications.

Advanced network features include switching protocols, virtual LANS (VLANS), traffic prioritization (QoS), and bandwidth aggregation. The MILTECH 24FO’s gigabit speeds and 28 VDC power make it instantly compatible with any network device and power systems. Its mechanical packaging enhancements, including ruggedized Amphenol SIM 2D 44VG connectors, is designed for MIL-STD-810F airborne and ground environmental compliance and high reliability.

Plating Measurement System

Bowman (Schaumburg, IL) has debuted an addition to their suite of bench-top XRF plating measurement systems. Bowman’s G Series XRF is a robust system that’s ideally suited for jewelry, connectors, and other precious metal analysis. Because it quantifies zinc, zinc-nickel and other anti-corrosion coatings, it is also ideal for components such as fasteners.

The two most distinctive features of the G Series are “bottom-up” measurement using a motorized Z-axis with laser-based auto-focus, and precision video imaging. An available manual XY stage with 1.5" × 1.5" travel facilitates easy positioning of small and large parts.

The standard G Series configuration includes a single fixed collimator, solid-state PIN detector, and long-life micro-focus x-ray tube. As with all Bowman models, the components can be upgraded to include multiple collimators, a variable focal camera, or an SDD detector. Like others in the Bowman XRF portfolio, G Series instruments simultaneously measure up to 5 coating layers, 10 elements in each layer, a total of 25 elements in all. Element range is Al (13) through U (92.)

E-Band Automotive Radar System

Irish company Arralis (Limerick, Ireland) announced the launch of its new E-Band automotive radar system. The Corvus Radar exceeds what is available in the current automotive marketplace in detection range, elevation resolution, and scan area, enabling multiple 3D target detection at up to 300m over a ±45° azimuth angle and ±7° elevation angle.

The system utilizes the Arralis Corvus MMIC portfolio and a patented analogue beamforming technique to enable detection of a 0 dBm2 target, for instance a fast approaching motorbike, at 300m distance. Monopulse is applied in both Azimuth and Elevation planes to enable resolving of targets angle within beams.

Angular Rate Sensor

Unlike an accelerometer that measures linear motion, the ARS3 PRO from DTS (Seal Beach, CA) measures high rates of angular velocity. From lever durability to life-cycle testing of a car door or RPM of a driveshaft, the miniature ARS3 PRO is designed to be positioned near the point of interest. The aluminum 19 mm × 19 mm × 12.5 mm enclosure is IP67 rated, weighs only 9 grams and is shock rated to 10,000g. The triaxial package is 50% smaller and 40% lighter than even three DTS ARS PRO uniaxial sensors on a mounting block. Available in ranges from ±300 to 50K deg/sec and in multiple bandwidths, the ARS3 PRO features DC response and shunt check capabilities.

FPGA Development Tools

Pentek, Inc. (Upper Saddle River, NJ) recently introduced several enhancements to its Navigator Design Suite for the Xilinx Zynq UltraScale+ RFSoC. New IP expands Pentek’s existing IP library to over 140 cores for FPGA development on its Quartz Architecture platform. Pentek’s Navigator Design Suite includes the Navigator FDK (FPGA Design Kit) for integrating custom IP into Pentek factory-shipped designs and the Navigator BSP (Board Support Package) for creating host applications.

Starting with the FDK, new cores support the RFSoC on-chip A/D and D/A converters with the following new features. Data acquisition and waveform generator cores have been updated that include support for VITA 49.2 VITA Radio Transport (VRT) packet formatting. A new optimized ×16 decimation core extends the range of the built-in RFSoC decimation. Pentek’s Smart A/D Calibration feature adds hardware, FPGA IP and software to make Xilinx’s calibration circuitry more robust across diverse operational scenarios. The programmable signal synthesizer core now includes a programmable frequency sweep generator, ideal for generating radar chirp pulse waveforms. These new cores for Quartz support operation of all eight RFSoC A/D and D/A converters simultaneously.
