High Temp Accelerometer from Measurement Specialties
Hampton, VA — Measurement Specialties (NASDAQ: MEAS) now offers a robust, DC-response accelerometer that operates in temperatures from -55 to +170°C. The new MEMS-based 4604HT accelerometer provides an amplified output as well as critical dampening to a -80dB/decade response attenuation for excellent high frequency signal suppression and improved measurement accuracy. The signal-conditioned unit offers an expansive dynamic range from ±2 g's to ±200 g's for a variety of onboard monitoring applications that need a low-cost, high performance sensor. Its high-g shock protection via integral over-range stops makes the 4604HT suitable for flight testing, road vehicle testing and performance testing as well as for flutter and nacelle vibrations and down hole monitoring.
The accelerometer also includes integral strain relief, further enhancing measurement accuracy. Typical parameters at ±2 g's include sensitivity of 1,000mV/g, a frequency response of 0-200Hz and residual noise of 600µV rms.
Excitation voltage of the new 4604HT is 8 to 18VDC and excitation current is less than 5mA. Thermal sensitivity shift is ±4 percent over the full temperature range. The sensor comes in a hermetically-sealed anodized aluminum housing with an epoxy seal rated to IP65.
