Endevco announced the release of Model 2262B, a rugged, gas-damped piezoresistive accelerometer for shock environments. This new transducer uses a unique and advanced multi-mode damped silicon piezoresistive MEMS sensing element for exceptional bandwidth with no significant resonance response up to 40 kHz. Model 2262B is available in 1000, 2000, and 6000 g full-scale ranges. […]

What advanced sensing techniques are used to find lost treasures? Part 2: Electromagnetic induction
Part 1 of this series addressed magnetometry. Another sensing technique used by archeologists and treasure hunters to find objects is electromagnetic induction (EMI or EM). EMI sensing measures the change in mutual impedance between a pair of coils on or above the earth’s surface. Typical EMI instruments use two or more sets of coils, electrically […]
