Piezoelectric
Accelerometer Endevco Model 6237M70/M71
The Endevco Model 6237M70 and 6237M71 Piezoelectric
Accelerometers are designed specifically for use in extremely
high temperature environments such as those experienced
on aircraft gas turbines. These Piezoelectric Accelerometers
are designed for continuous operation at +1,200°F with
long Mean Time Between Failure (MTBF). The small size
and light weight of these Piezoelectric Accelerometers
permit installation in cramped locations with minimal
structural support. The accelerometer is a self-generating
device that requires no external power source for operation.
Models 6237M70/M71 incorporate Endevco's Piezite®
Type P-15 crystal in a shear design. The 6237M70 and 6237M71
differ in their internal design and in the direction of
the sensitive axis. The 6237M70 has its sensitive axis
located in line with the mounting screw, while the 6237M71
is oriented perpendicular, or transverse, to the mounting
screw. The sensing elements and integral shield are isolated
from the case. These accelerometers feature and integral
hardline cable with a standard length of 120 inches. Other
cable lengths are also available on special order.
Endevco Signal Conditioner Model 2721B is recommended
for use with this high impedance accelerometer.
Features:
• Requires no external power
• Gas Turbine Monitoring
• +1,200°F (+650°C) operation
• Integral hardline cable
• Single bolt mounting
• Ground isolated
