PCB Piezotronics launches two new differential output charge
accelerometers for gas turbine bearing monitoring
PCB Piezotronics,
a world leader in vibration, acoustic, pressure, force and torque
sensors has launched two new hazardous area approved differential
output charge accelerometers from IMI Sensors that are designed
for use in high temperature applications.
IMI developed the new sensors for gas turbine monitoring, commissioning
of nuclear power plants and machinery monitoring in high temperature
environments.
Model EX615A42 is designed for use in environments up to 260°C
and offers sensitivity of 100pC/g, a measurement range of ±200g
peak and a frequency range of 5kHz ±5%. The sensor has
a stainless steel housing and features a 3m armoured, low-noise
PTFE cable terminating in pigtails.
The second accelerometer - model EX619A11 - is capable of operation
up to 482°C with sensitivity of 50pC/g, measurement range
of ±500g and frequency range of 3kHz ±5%. This
sensor has a nickel housing with an integral 2.1m MI hardline
cable terminating in a 2-pin MIL-C-5015 connector.
Additional characteristics of the new IMI Sensors high temperature
charge output accelerometers include ATEX approval, high shock
survivability, high resolution and large dynamic range option.
PCB Piezotronics also offers several differential charge amplifiers
to support the two new sensors that convert the high impedance
output to a low impedance voltage signal for transmission and
data collection. When paired with charge accelerometers, these
charge amplifiers convert the sensor output into a single-ended
output (measurement output as a signal and ground).
