Isotron ® accelerometers
Model 65HT
The Endevco model 65HT-05 triaxial accelerometer is a miniature,
high-temperature device packaged in a 10-mm cube of welded titanium
construction and weighs only five grams. Using the latest technology in
high-temperature components and processes, its micro-electronic
circuits are designed and built specifically to operate up to +175°C with
a sensitivity of 0.5 mV/g.
> Triaxial, low-impedance output
> Shock-proof, overload-protected
> Small size and lightweight (10-mm cube, 5 grams)
