Charge output accelerometer will tolerate temperatures of up to 704°C
23 June 2013
PCB Piezotronics has introduced a high temperature charge output accelerometer that can be used in high temperature environments such as gas turbines and nuclear power plants.

Able to tolerate temperatures of up to 704°C, the new PCB series EX611A20 is suitable for gas turbine bearing health monitoring, condition monitoring and structural damage monitoring.
Packaged in an hermetically-sealed Inconel industrial housing, the EX611A20 is ATEX approved for Ex ia IIC T6 to T710C and comes with integral 3m hard-line cable terminating in a LEMO connector as standard. Other connectors (e.g. 2-pin mini MIL) and cable lengths are available to order.
The accelerometer is a drop-in replacement for existing competing products but offers significant advantages over these in terms of warranty, pricing, lead time and height.
PCB’s model EX611A20 features shear mode sensing elements that are less sensitive to thermal transients than the compression mode sensors used in competing products.
The product is compatible with various differential charge amplifiers such as models 422M182 and 422M183.
