MEGGITT HTP | SENSORS | UNIAXIAL ACCELEROMETERS

  • 6233C-XX
6233C Piezoelectric Accelerometer
  • Piezoelectric accelerometers designed for high temperature vibration measurement of gas turbine engines
  • Temperarure range: -54ºC to 482 ºC
  • Designed for continuous operation to +482°C with long Mean Time Between Failure (MTBF). The accelerometer is a self-generating device that requires no external power source for operation
  • Frequency response +/-5% from 10 to 5000 Hz, 10 to 2500 Hz and 10 to 2000 Hz.
  • Requires the use of a charge amplifier or remote charge convertor which is designed to accept a 100 kΩ source resistance
  • Sensitivity 10 pC/g, 50 pC/g and 100 pC/g
  • 6237M70
6237M70 SENSOR
  • Piezoelectric accelerometers are designed specifically for use in extremely high temperature environments such as aircraft and ground-based gas turbines. These accelerometers are designed for continuous operation at +650°C.
  • Temperature Range: -55 to 650 ºC.
  • Amplitude response +/-5% from 1 to 3000 Hz.
  • No external power source required.
  • Optional charge amplifier.
  • Sensitivity 10 pC/g +/-5%.
  • 6240M10
6240M10 SENSOR
  • Piezoelectric accelerometers are designed specifically for use in extremely high temperature environments such as aircraft and ground-based gas turbines.
  • Temperature range: -55 a 650 ºC on continous operations.
  • Designed for continous operations at 650ºC and intermittently at 760 ºC.
  • Amplitude response +/-5% from 30 to 2000 Hz.

  • 6235M1
6235M1 sensor
  • Piezoelectric accelerometer designed for high temperature vibration monitoring and use in high temperatures, wet and dusty environments, and where high radiation is encountered.
  • Accumulated radiation of 1010 rad and up to 1018 thermal neutrons/cm2 can be tolerated.
  • Designed for continuous operation to 482°C.
  • Temperature range: -196 to 482 ºC.
  • Amplitude response +/-1dB from 1 to 9000 Hz.
  • Recommended signal conditioner, models 2777 A and 6634C.
  • Sensitivity 10 pC/g +/-5%.
  • 2273AM1/AM20
2273AM1 accelerometer
  • Piezoelectric accelerometers specially designed for use in nuclear-reactor-vibration and loose-parts-monitoring systems.
  • The construction provides mechanical isolation of the seismic system from the mounting base, resulting in very low strain sensitivity. The case is made of Inconel and provides for hermeticity through welding and glass-to-metal fusion at the connector
  • Temperature Range: -55ºC a 399 ºC
  • Frequency response +/-5% 20 a 5000 Hz
  • Requires no external power source.
  • Sensitivity 10 pC/g

2248_1 accelerometer
  • Small piezoelectric accelerometer for shock and vibration measurement of structures subjected to very high temperatures
  • The accelerometer is a selfgenerating device that requires no external power source for operation
  • The design provides mechanical isolation of base strain from the mounting surface. Signal ground is connected to case.
  • Temperature Range: -54º C a 482 ºC
  • Frequency response +/-5% desde 1 a 5000 Hz
  • Charge Sensitivity 3 pC/g

Meggitt HTP origins after the divestures of low temperature activities related to the Endevco brand.

In fact Meggitt Energy Equipment retained all products with operative capabilities above 260°C

As a leading provider of pressure and vibration sensors for the most demanding aerospace, nuclear, turbine

and industrial control measurement applications, Meggitt’s advanced sensors are specialized to withstand the

challenges of extreme environments.

Over a half century of high temperature innovation from Meggitt

  • 1970’s First high temperature (900°F, 482°C ) piezoelectric crystal developed
  • 1980’s First tourmaline sensor developed (1400°F, 760°C)
  • 2019 Higher temp sensor developed (1500°F, 815°C)

Long term, stable performance
