Battery Powered ICP® Sensor Signal Conditioners

Battery powered signal conditioners provide a portable, convenient method for powering ICP® sensors and ICP® in-line charge converters. Integration into any measurement chain is easy. Simply connect a cable from the sensor to the input and a cable from the data acquisition system to the output. When power is turned on, they are ready to condition signals for transmission to the readout device.

These units are powered with standard 9-volt alkaline batteries and provide an AC coupled output. Each signal conditioner features a color coded meter on the front panel that monitors sensor operation and detects cable faults.


  • Compact and Portable
  • Battery operation eliminates line noise
  • Easy-to-use
  • Built-in fault meter


  • Vibration testing for low channel counts
  • Low noise acoustic testing
  • Vehicle and component durability tests
