The Model 41 is a small piezo resistive single axis crash test accelerometer designed to be compliant to SAE-J2570 and ISO-6487 specifications. This DC accelerometer features built-in mechanical
stops, anodized aluminium alloy housing and an integral low noise cable designed for high-g shock testing. The 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 IP61 protection over the full operating temperature range of -20°C to +80°C. The sensor also supplies the calibration data in a user friendly excel format which enables high volume users to quickly upload the calibration This accelerometer is designed for harsh test applications and is packaged in an anodized ground isolated Aluminium 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 accelerometer has the same identical form factor as the Kyowa ASM-A-ID and ASM-1KBCV series accelerometers and can be used as drop-in replacements. 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.
