Unholtz Dickie

Unholtz-Dickie

Unholtz-Dickie is a US manufacturer based in Wallingford, Connecticut, specializing in high-precision piezoelectric accelerometers, vibration sensors, and signal conditioning equipment. The company has supplied the aerospace, defense, and industrial testing industries for decades with ruggedized transducers and charge amplifiers designed for demanding environmental conditions. Their accelerometers are qualified for use in shock and vibration qualification testing, structural dynamics analysis, and modal testing programs.

Unholtz-Dickie's charge amplifiers and IEPE signal conditioners interface directly with their accelerometer product line, providing low-noise signal conditioning for precision vibration measurement chains. The company's product range supports both laboratory test setups and field measurement applications where high accuracy and reliability under temperature extremes and mechanical stress are required.

Key Product Lines

• Piezoelectric Accelerometers — IEPE and charge-mode sensors covering a wide range of frequency response, amplitude, and environmental specifications
• Charge Amplifiers — D-series amplifiers for converting charge-mode accelerometer output to voltage signals for data acquisition systems
• Vibration Measurement Systems — integrated sensor and conditioning systems for shock and vibration testing in laboratory and field environments

Industries Served

Unholtz-Dickie accelerometers and vibration sensors are used in aerospace and defense qualification testing, automotive component and NVH testing, structural and modal analysis, seismic monitoring, nuclear and power generation equipment testing, and R&D laboratories requiring traceable, high-accuracy vibration measurement.
