The Model 3700 is a MEMS piezoresistive shock accelerometer in a rugged stainless steel package.
Description: The Model 3700 is a MEMS piezoresistive shock accelerometer in a rugged stainless steel package. The accelerometer is available in ranges from ±50g to ±6000g and is ideal for long duration shock transient measurements. The accelerometer incorporates mechanical over-range stops and is packaged in an industry standard footprint.
Features: • DC Response • ±50g to ±6000g Dynamic Range • 20,000g Shock Protection • No Zero Shift • Rugged PFA Jacketed Cable • mV Output • Stainless Steel Housing
