3700 Series Accelerometer

3700 Series Accelerometer

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
