The following companies will be exhibiting at Sensors Expo & Conference 2017. The event, held in the San Jose, CA-based McEnery Convention Center, runs from June 27-29.

Gait-Analysis Sensing System

Tekscan (Boston, MA) has announced the Strideway system for gait analysis. The platform provides kinetic, temporal, and spatial gait parameters, as well as pressure and force data. With a wider active area and flush surface, Strideway minimizes trip hazards and accommodates patients with mobility aides (like a walker) or those with gait dysfunctions. Customers can add length onto the system at any time as their needs change. Booth #: 825

PCB Piezotronics (Depew, NY) offers a miniature “teardrop” ICP® accelerometer. The Model 352A74 features a sensitivity of 100 mV/g and a measurement range of ±50 g peak. The sensor, hermetically sealed in a low-profile titanium housing, can be adhesively mounted for vibration testing of electronic components, circuit boards, and other small structures.

A flexible, one-foot, twisted-pair integral cable enables easy mounting in tight spaces. The cable is spliced into a heavier gauge coaxial cable for a length of 10 feet, terminating in a 10-32 connector. With built-in microelectronic signal conditioning circuitry, Model 352A74 provides a low-noise, low-impedance output signal while permitting long-distance signal transmission. The accelerometer operates in -65 to +250 °F temperatures and survives accidental shock inputs to ±5,000 g. Booth #: 916

Gas Sensor

The SGP gas sensor from Sensirion (Staefa, Switzerland/Chicago, IL) fits four gas sensing elements into a 2.45 × 2.45 × 0.9 mm3 DFN package. The device features a fully calibrated air-quality output signal. The SGP enables integration of metal-oxide gas sensors into mobile devices. Sensirion’s proprietary metal-oxide technology and multi-pixel platform offer robustness against contaminants. Booth #: 423

Liquid Sensor

A liquid sensor from SST Sensing Ltd. (Coatbridge, Scotland) detects leaks using built-in microcontroller functionality. Requiring no moving parts, the liquid-level switch employs an infrared sensing mechanism. If a liquid contacts the sensor tip, the device changes the properties of the optical setup. Less light is thus incident on the device’s phototransistor, leading to change in output voltage. The Optomax-based product allows telecom operators/carriers to be rapidly alerted of the presence of water in their fiber-optic cabinets, base stations, and pico cells. The sensor supports temperature ranges from -25 to 80 °C. Booth #: 316

Audio Processor

A new audio processor from ROHM Semiconductor (Kyoto, Japan/San Diego, CA) performs volume adjustment and audio mixing for car audio and navigation systems. The BD34602FS-M extracts the full data from audio sources by optimizing 28 unique parameters centered on circuit configuration and electrical characteristics that have been shown to impact IC sound quality. A built-in mixing circuit integrates popping-noise reduction technology. 0.004% distortion and 3.1uVrms floor noise capabilities make it possible to extract the full data from sound sources, improving spatial representation (location of sound source and perceived distance).

Inertial Sensors

LORD Sensing MicroStrain (Williston, VT) has announced the 3DM-CV5 series of industrial-grade inertial sensors: the CV5-10 IMU, the CV5-15 VRU, and the CV5-25 AHRS. Applications for the CV5 line of sensors include vehicle health and usage monitoring, precision agriculture, platform stabilization, and artificial horizon. The board-level OEM sensors feature precision-mounting alignment capabilities that allow for a direct PCB mount or a chassis mount with a ribbon cable. The low-noise accelerometer includes a standard range of ±8 g and optional ±2, ±4, ±20, and ±40 g. The gyroscope also measures ±500 degrees per second or an optional ±250 and ±1,000 degrees per second. Booth #: 530

Gas Detectors

Laser Gas Detectors from Axetris (Itasca, IL) spot methane and carbon dioxide simultaneously. The devices can be used in medical applications, such as breath analysis. Elevated methane levels suggest indigestion and are a possible indicator of fructosemia or lactose intolerance. Carbon dioxide, another quality indicator, signals whether the subject is taking sufficiently long and deep breaths. An alternative to more invasive procedures, the spectroscopic analysis of breath air potentially shortens the period needed to conduct tests from hours to seconds. Booth #: 924

Linx Technologies (Merlin, OR) has introduced the Industrial Dipole Antenna. The ½-wave centerfed antenna operates at 2.4 GHz. Industrial and outdoor applications include outdoor meters, solar panel controls, and other sensor monitoring and control systems. The ID Series antenna has a bracket molded into the assembly, which protects against stresses that may occur during installation or operation in an indoor or outdoor environment. The material used in both the antenna structure and the cable itself has a temperature range of -40 °C to +85 °C. Booth #: 1140
