An accelerometer is a device that measures acceleration, which is the rate of change of velocity. Essentially, it tells you how quickly something is speeding up or slowing down. Imagine you're in a car that's accelerating quickly - an accelerometer would sense that change in speed and measure its intensity.

Piezoelectric (PE) accelerometers

All mechanical accelerometer designs are based on a simple spring-mass principle in which strain is generated in relation to amplitude and frequency of the dynamic motion. In a PiezoElectric (PE) accelerometer, this strain is applied directly to the PE element, which develops an electrical charge proportional to mechanical motion. Different material and configurations of PE accelerometer elements are used to support specific applications.


Piezoresistive (PR) accelerometers


Strain gauge accelerometer designs based on a Wheatstone bridge arrangement consist of a rugged monolithic assembly with solid-state MEMS resistors that change in resistance in proportion to applied mechanical strain.

Integrated electronics piezoelectric (IEPE) accelerometers

The acronym IEPE refers to a type of piezoelectric (PE) accelerometer with internal electronics (IE) that allows it to convert charge to a low-impedance voltage output. Its temperature response is somewhat limited due to its onboard electronics. This type of accelerometer is primarily specified for applications in which environmental conditions permit its use, including HALT/HASS/ESS testing, industrial vibration monitoring and general purpose vibration and shock testing. Since both PE and IEPE types are AC-coupled designs, the acceleration output of these accelerometers cannot be used to yield correct velocity and displacement information by numerical integration.


Variable capacitance (VC) accelerometers

Feature a silicon MEMS capacitive sensing element that is anodically bonded to a lid and base to form a parallel plate, differential capacitor pair. The accelerometers feature DC response, gas damping for good frequency coverage and rugged construction. Integral electronics with DC excitation provide a high-level, low-impedance output signal that is stable.

Pressure Transducers


A pressure transducer is a transducer that produces an electrical output proportional to the pressure applied. The frequency of pressure fluctuation should be lower than the resonant frequency of the transducer, and the electrical output is essentially independent of frequency below one-fifth the resonant frequency (flat frequency response). When pressure is applied, the force on the sensing element due to the pressure results in a deformation of the sensing element. This deformation changes the resistance of the element and the electrical output of the transducer. In a well-designed transducer, the deformation and electrical output are directly proportional to pressure over a wide range of frequencies.

Gage pressure transducers

Endevco stands out for its diverse range of gage pressure transducers, renowned for their simplicity, portability, and cost-effectiveness. Unlike absolute pressure transducers, these measure pressure relative to the surrounding air, eliminating the need for external reference connections, ideal for applications like pneumatic and hydraulic systems, automotive testing, industrial process control, and environmental monitoring. Popular models include the miniature and high-sensitivity 8507C, perfect for dynamic measurements, the rugged and reliable 8510B for industrial use, and the high-performance 8515B designed for demanding aerospace and defense applications. When choosing your Endevco gage pressure transducer, remember to consider factors like pressure range, accuracy, temperature range, media compatibility, and output signal to ensure a perfect fit for your specific needs.


Absolute pressure transducers

Absolute pressure transducers from Endevco provide unmatched accuracy and reliability, excelling in demanding fields like aerospace, defense, and vacuum technology. They measure pressure relative to a perfect vacuum, offering a complete picture regardless of surroundings. Models like the high-performance 8515C and the versatile 8530C showcase their commitment to precision and durability.


Endevco microphones specialize in capturing sound, not just any sound, but high-intensity and sensitive sound measurements. While different from your typical microphone used for recording music or vocals, Endevco's focus on precision, reliability, and durability makes them ideal for demanding applications.


High intensity microphones

Endevco roars into the high-decibel arena with its exceptional line of high-intensity microphones, built to conquer ear-splitting sound pressure levels while meticulously capturing every sonic detail. From jet engine shrieks to explosive booms, these microphones can handle it all, with ranges spanning 140 dB to a bone-rattling 180 dB.
