IMI Sensors, a division of PCB Piezotronics, Inc., announces the worldwide launch of the company’s 600B13/B14 high temperature accelerometer kits for vibration measurement in gas turbines. These high temperature accelerometer kits include a side-exit charge mode sensor, 10-foot integral hermetically sealed hard-line cable, and integral ICP® charge amplifier for multiple power generation monitoring applications, including placement on turbines, exhaust systems, and piping in extreme heat environments of +900°F/+482°C.
The new shear mode sensing element of the 600B13/B14 provides significantly improved performance for dealing with transient temperature changes and spiking, a common condition in gas turbines. In addition, by incorporating an integral sensor, cable, and charge amplifier in a single high-temperature accelerometer kit, gas turbine operators have a complete measuring chain that eliminates contamination and common mode noise concerns. The integral ICP® charge amplifier allows for use with standard data acquisition equipment.
IMI’s 600B13/B14 kits are designed as drop-in replacements for existing accelerometers with ARINC® three-point mounting bases, and have a higher temperature range than many competing sensor types. Model 600B13 has 100 mV/g (10.2 mV/(m/s²)) sensitivity and Model 600B14 has 10 mV/g (1.02 mV/(m/s²))sensitivity. The wide frequency range for 600B13/B14 is (±5%) 282 to 240000 cpm (4.7 to 4000 Hz), making them ideal high temperature accelerometer kits for the measurement of gas turbine vibration.

In addition to my previous message, we also need to measure the vibrations from this sensor in the range of 0-2 g or 0-19.6m/s2 and do a double integration in the protection device to derive the Displacement value to be measured in the Range of 0-16 Mils or 0-400 um. Trip action is needed on both acceleration and displacement setpoints. Do you also make a Double integrator to output the displacement value? If so please also quote that.
