Auto Crash Sensor

Meggitt Sensing Systems (Irvine, CA) introduced the Endevco model 7264H optimally gas-damped accelerometer for automotive safety testing. The sensor is small in size and mass, and eliminates irrelevant frequency content generated by breaking glass and metal-to-metal impact. The MEMS accelerometer performs consistently over temperatures ranging from –18 to +66 °C (0 to 150 °F), and has a .50:.85 damping ratio and a 10,000g shock capacity. The frequency response is flat from DC to 3,500 Hz. It has a two-active-arm, full-bridge circuit with fixed completion resistors to facilitate shunt calibration. The full-scale output is 200 mV nominal with 10 Vdc excitation. The accelerometer comes standard with 2-, 5-, and 10-volt calibration data.

Rotational Speed Sensors

RHEINTACHO Messtechnik GmbH (Freiburg, Germany) introduced the FQ series of plastic sensors for detecting rotational speed and direction. The sensors feature an IP69K protection class rating, which means they can withstand powerful, high-temperature water jets. The sensors offer different cable lengths, connectors, cable outlet directions, detection distances, and EMC. Standard insertion depths are 30, 35, and 45 mm. The sensors have a frequency range of 0.1 Hz to 20 kHz, and an operating temperature range of –40 to +140 °C.

World's 'Smallest Magnifying Glass' Supports New Sensors

Using tiny particles of gold, researchers from the University of Cambridge have concentrated light to smaller than a single atom. By focusing the light to just under a millionth of a meter, the scientists have a "magnifying glass" that reveals individual chemical bonds within molecules.

Military Sensor Inspires Instrument to Search for Life on Mars

This artist’s rendition shows how BILI could operate on Mars. (NASA) A sensing technique used by the U.S. military currently to remotely monitor the air to detect potentially life-threatening chemicals, toxins, and pathogens has inspired a new instrument that could “sniff” for life on Mars and other targets in the solar system.
