Accelerometers

PCB® Automotive Sensors Division (Depew, NY) offers MEMS DC response accelerometers for improving the precision of low-frequency vibration and motion in automotive applications. Available in full-scale ranges from ±2g to ±200g, the accelerometers come in single-axis (Series 3711E and Series 3741E) and triaxial (Series 3713E) configurations. The units include gas-damped, silicon MEMS sensing elements. Series 3711E and Series 3713E have a hermetically sealed titanium case, and Series 3741E units have a rugged anodized aluminum housing for harsh environments.

Power Monitoring

Microchip Technology (Chandler, AZ) introduced the MCP39F511 single-phase power monitoring IC designed for real-time measurement of AC power. It is designed for use in high-performance commercial and industrial products such as lighting and heating systems, smart plugs, power meters, and AC/DC power supplies. To address industry requirements for better accuracy across current loads, additional power calculations, and event monitoring of various power conditions, the IC provides popular standard power calculations combined with advanced features. The import and export of active energy accumulation, four-quadrant reactive energy accumulation, zero-crossing detection, and dedicated PWM output have been integrated on-chip, along with the ability to measure active, reactive, and apparent power; RMS current and RMS voltage; line frequency; and power factor.

Voltage Meter

Dean Technology (Carrollton, TX) announced the HVM40B digital voltmeter for measurement of positive or negative voltages up to 40,000 Volts. It features an LED display, solid-state design, and dual-range measurement providing resolution below 20 kV. Other features include retractable feet, optional tilt handle, and optional rack-mount hardware. Input impedance of 10 giga-ohms minimizes circuit loading. It conforms to UL and CSA standards, and comes with various worldwide power cords. For Free Info Visit http://info.hotims.com/55592-413

Corrosion Detection

The ThermoCam LC (TCLC) from EVT Eye Vision Technology (Karlsruhe, Germany) detects surface defects such as cracks, pores, stripes, dents, and corrosion. The infrared camera detects corrosion that is invisible under the surface using the Impuls-Thermography method. The TCLC recognizes the defects as “hot spots.” A flash heats the surface, and the camera records the cooling of the material. Up to 100 images per second are delivered. The camera features noise (NETD) of 0.2 K, a measurement range from -50 to +300 °C, a field of view of 32 x 8 pixels, and opening angle of 40, 60, or 120°.

Dynamic Signal Analyzer

Data Translation (Marlboro, MA) announced the DT7837 ARM-based dynamic signal analyzer module for noise and vibration measurement. The computer portion of the module uses a ruggedized BeagleBone Black ARM processor. Complete source code is provided that can be modified and used without any restrictions. The front-end design allows simultaneous measurement of four 24-bit IEPE sensor inputs at a sampling rate of 102.4 kS/s. The module is used for precision measurements with microphones, accelerometers, and other transducers that have a large dynamic range. It also includes a 24-bit stimulus output, tachometer, general-purpose digital I/O, external trigger functions, and counter/timers. The ARM block processor includes BBB functions, FPGA, memory and support peripherals, interfaces for a USB host and client, Ethernet, power, and SD card.

Portable Analyzer

The Thermo Scientific Gemini analyzer from Thermo Fisher Scientific (Tewksbury, MA) provides FTIR and Raman spectroscopy in a single, handheld instrument. The analyzer is designed for chemical response personnel, explosive ordnance disposal (EOD) technicians, and other responders requiring heavy equipment for lengthy durations. The analyzer includes a library that enables operators to identify unknown solids and liquids, from explosives and chemical warfare agents to industrial chemicals and precursors. For substances identifiable by both Raman and FTIR, the analyzer provides comprehensive analysis, and can switch between analysis techniques using a tactical keypad or touchscreen. Features include Scan Assist to guide the operator through technology selection and sampling, a motorized anvil that adjusts sample pressure based on user settings and enables Scan Delay for FTIR analysis, and built-in safety features to protect against potentially hazardous substances.

Laser Micrometer

Micro-Epsilon (Raleigh, NC) offers the optoCONTROL 2520 compact laser micrometer with integrated controller and a Web interface that runs on HTML5 instead of Java. It features a 46-mm measuring range and a maximum transmitter/ receiver distance of up to 2 m. The Web browser interface for configuration and setup does not require installation of any additional software. The cross-device sensor enables the user to run it from a smartphone. A measurement chart displays limit values. In addition, the system provides various averaging and filter methods, as well as statistics features. Up to eight segments can be measured and output simultaneously. The user can switch the display from metric (mm) to Imperial (inch) measurement units. The smallest object diameter detectable is 0.5 mm. Data output is performed via RS-422, Ethernet, or EtherCAT interfaces. For Free Info Visit http://info.hotims.com/55592-409
