Endevco® Model 6240M10 Extreme High Temp Accelerometer to 7600 pages

Model 6240M10
Piezoelectric accelerometer
Features

Description

•t High-temperature operation (+760°C)
•t Hermetically sealed
•t Ground-isolated
•t Requires no external power
•t Aircraft gas-turbine testing

The Endevco® model 6240M10 piezoelectric
accelerometer is uniquely designed for continuous
operation at +1200°F (+650°C) and intermittent operation
up to +1400°F (+760°C). The 6240M10 is ideally suited
for applications on aircraft gas-turbine engines as part
of vibration monitoring systems. The 6240M10’s small
size allows for installation in cramped quarters. It also
features a relatively high sensitivity for low-level vibration
analysis. The accelerometer is a self-generating device
that requires no external power source for operation.
Electrical connection is made through an integral hardline
triaxial cable terminated with a 10-32 receptacle. Cable
assemblies 3075M21 (482°C), 3075M6 (482°C) and 3090C
(260°C) are designed to mate with this receptacle. The
sensing elements and integral shield are isolated from the
case. The standard cable length is 120 inches, however,
other cable lengths are also available on special order.
Endevco signal conditioner model 2721B is recommended for use with this
accelerometer. The 2771C remote charge convertor may also be compatible
for applications using this high-impedance accelerometer, depending on the
temperature the accelerometer will be exposed to.
