ICP® Signal Conditioners

PCB Piezotronics manufactures precision accelerometers to measure vibration, shock, acceleration, and motion for monitoring, control, and testing applications. ICP®, PE, MEMS and Capacitance sensing technologies are used to fulfill a wide assortment of measurement requirements. Accelerometers are used by field test, in factory production and design as well as Research and Development organizations to acquire critical data. In addition to our precision miniature units, rugged accelerometers and vibration sensors for industrial machinery vibration monitoring are offered by our IMI Sensors division.

Single Axis and Three Axis Accelerometers

PCB's single axis and three axis (triaxial) accelerometer configuration parameters include sensitivity, temperature, frequency response, amplitude response, form factor and lead wire grounding. Accelerometers are critical for evaluating proper performance of equipment or structures. Such applications usually require proof of calibration of the entire measurement system from the sensor through to the final output. PCB calibrates all products traceable to NIST and includes a calibration certificate with each sensor shipped.

ICP® Accelerometers

The most commonly used technology is ICP® accelerometers. These sensors require ICP® Power supplied. Most modern data acquisition, digital control, and portable data systems provide ICP sensor power. ICP Sensors can be referred to as Voltage Mode output sensors. Our PE sensors can be referred to as Charge Mode output sensors. Each directional axis measured requires one channel of the data system or signal conditioner.
