IMI stands for Industrial Monitoring Instrumentation, and IMI Sensors is a division of PCB Piezotronics, Inc. To address a need in the industry for rugged durable sensors for monitoring machinery, IMI Sensors was established in 1990. Today IMI designs and manufactures low cost industrial accelerometers, transmitters, pressure sensors, vibration switches and electronics for a wide array of industrial applications. Some markets served include the predictive maintenance (PdM), process monitoring & protection, and power generation & energy industries.

The backbone of the company is its mission statement: Total Customer Satisfaction. This mission is not only supported by products that offer great value, but also by an unconditional warranty. Factory applications engineering and a worldwide network of sales offices and representatives are readily available to assist with customer requests.

PCB Piezotronics was founded in 1967 as a manufacturer of piezoelectric quartz sensors, accelerometers, and associated electronics for the measurement of dynamic pressure, force, and vibration. The unique expertise of the company was the incorporation of microelectronic signal conditioning circuitry within these sensors to make them easier to use and more environmentally compatible. These ICP® sensors gained wide popularity and became the foundation for the company's success.

Subsequent growth and steady investment in facilities, machinery, and equipment permitted a constant broadening of the product offering. Measurement capabilities expanded with the addition of piezoceramic, tourmaline, capacitive, piezoresistive, and strain gage sensing technologies. Ensuing products include industrial accelerometers, DC accelerometers, load cells, torque sensors, microphones, pressure transmitters, and calibration equipment.

The backbone of the company is its mission statement: Total Customer Satisfaction. This mission is not only supported by products that offer great value, but also backed by our industry exclusive Lifetime Warranty Plus. Factory applications engineering and a worldwide network of sales offices and representatives are readily available to assist with customer requests.

PCB Piezotronics, Inc. was established in August of 1967 by Robert W. Lally and James F. Lally.  The focus of their technical efforts was primarily on the development and application of integrated circuit technology to piezoelectric sensors.  Beginning with the creation of sensors to measure cylinder combustion pressure, PCB's product line quickly expanded to include vibration and force sensors.

Other products such as impact hammers, multichannel signal conditioners and actuators followed to meet increasing customer demand.  It was this flexibility in design / manufacturing, coupled with PCB's commitment to 'Total Customer Satisfaction', that is responsible for the success of PCB.

PCB Quality Systems are certified to the requirements of the following International Standards (available for download on this web page):

  • ISO17025 and ANSI-Z-540-1: Requirements for Competence of Testing & Calibration Laboratories,
  • EN13980 & Directive 94/9/EC: Quality Systems for Potentially Explosive Atmospheres

These standards strive for process consistency and provide a means for continuous improvement while covering the entire product cycle, which includes contracting, product design control, manufacturing process control and inspection and test. In-house calibration of PCB sensors is conducted with full traceability to National and International Institutes of Standards and Technology (N.I.S.T., P.T.B). In addition, a complete listing of A2LA accredited calibration services is documented on PCB’s “Scope of Calibration” document(s).

International Standards

What are standards and how are they beneficial? Standards are documented agreements containing technical specifications or other criteria that are to be used consistently in an effort to ensure materials, products, processes or services are fit for their purpose. For example, the format of credit cards and phone cards was derived from an ISO International Standard. Adhering to this standard, which defines such features as such as the optimal thickness, means that the cards can be accepted worldwide. These and similar standards increase the reliability and effectiveness of the goods and services we use. Users typically have more confidence in products and services that conform to international standards. The aim is to facilitate trade, exchange and technology transfer through:

  • enhanced product quality and reliability at a reasonable price,
  • improved health, safety and environmental protection,
  • greater compatibility and interoperability of goods and services,
  • simplification for improved usability,
  • increased distribution efficiency, and ease of maintenance.

Assurance of quality system conformity is provided by certifying bodies and through our internal auditing system. In addition, our system remains compliant with obsolete or superseded standards such as: ISO 10012-1 (former MIL-STD-45662A), Guide 25, MIL-Q-9858 and MIL-I-45208. PCB is also compliant to nuclear power plant specification 10CFR50 Appendix B. If you require compliance to a product or application specific standard (such as RoHS, European CE Marking, or US test requirement MIL-STD-740-2) which was not mentioned, please contact the factory for additional information.
