TE Model 41 Crash Test Accelerometer: Designed for Crush Zone Testing
This DC accelerometer features built-in mechanical stops, anodized aluminum alloy housing and an integral low noise cable designed for high-g shock testing. This cable assembly is user repairable in case of damage during testing. The sensing element is fluid damped to extend useful frequency range and reduce the adverse effect of high frequencies ringing caused by sensor resonance excitation at high-g inputs. The Model 41 accelerometer is designed for crush zone testing and features an epoxy sealed for minimum IP-61 protection over the full operating temperature range of -20°C to +80°C. TE Connectivity also supplies the calibration data in a user friendly excel format which enables high volume users to quickly upload the calibration. This crash test accelerometer is designed for harsh test applications and is packaged in an anodized ground isolated Aluminum housing. The model 41 accelerometer is available in ranges from ±100g to ±2,000g and features a full-bridge configuration with a nominal 1000Ω impedance that offers quick warm-up time and minimal drift. The model 41 will provide a wider excitation range, ~3x greater sensitivity and FS output as well as higher bridge impedance for minimum self-heating of gages at power on. For a triaxial critically damped accelerometer version with identical performance, TE Connectivity also offers the model 43 crash test shock sensor.
