New ED Series Rotary Magnetic Encoders
Offer Improved Performance Over
Traditional Optical Encoders or Potentiometers
The new ED Series of magnetic encoders by Measurement Specialties provides a platform for traditional optical encoder and potentiometer replacement with several significant improvements over existing electro-mechanical designs. The advantages inherent in magneto-resistive (MR) technology enable more robust sensor system designs offering lower total cost.

Encoder models ED-18, ED-19, ED-20 and ED-21 can replace traditional encoders and potentiometers with a more robust rotational sensing solution.. |
MR technology offers non-contacting sensing, which allows the electronics to be shielded from the operating environment. The ED product family utilizes encapsulated (potted) electronics, virtually eliminating contamination in even severe conditions. Component life is greatly extended with the loss of traditional mechanical contacts or LED degradation present in optical devices. Performance in environmental extremes is also improved with extended temperature range and humidity capabilities.

MEAS to Showcase New Accelerometers and More at SAE World Congress
Measurement Specialties (MEAS) will showcase new accelerometers for auto safety testing at SAE World Congress, April 16-19, 2007 in Detroit. Featured at MEAS booth #407 in the new Safety, Testing and Simulation platform will be three new miniature triaxial accelerometers (models 68C, 63 and 53 featured below) used for crash testing. In addition, the Vibration Design Center at MEAS will also feature new Model 4621 with on-board signal conditioning for road dynamics testing as well as redesigned Models 64B and 64C for anthropomorphic dummy testing. Altogether, MEAS offers almost 20 accelerometer models for a variety of auto safety testing applications including dummies, sleds, seat belt restraints, road dynamics and crush zone.
Dan Slavik will be presenting “Triaxial Accelerometers for Auto Safety Testing” at the Safety Presentation Pod on Monday, April 16 at 1:30 p.m.
Other products on display include sensors for relative humidity and temperature that can be used for cabin climate control and engine performance monitoring; thermopiles for non-contacting temperature sensing; and low cost OEM load cells for passenger detection and safety applications.
