Piezoelectric Sensors

What are Piezoelectric Sensors?

Piezoelectric sensors are piezo elements that convert environmental conditions into readable and usable electrical signals. There are two types: active and passive. The former sends ultrasonic signals and waits for a response, after which it releases an electrical signal. Information regarding distance and depth can be obtained when analyzing the delay. The latter only send signals when they receive inputs and do not do anything otherwise, hence the name. More details regarding the mechanics can be found here.

Why would you use a Piezoelectric Sensor?

Piezoelectric materials stay operational within a very large range of conditions (i.e. temperature, magnetic fields) and thus hold high value in collecting extreme data, such as those in explosions. Piezoelectric sensors have many other benefits as well: highly customizable shape, wide operational ranges, extreme responsiveness, etc. This, combined with very linear input/output relationships, makes piezoelectrics invaluable to laboratory settings.

Piezo sensors can be manufactured in a variety of shapes and sizes, including piezo discpiezoelectric tube, piezo ring, and other custom piezo elements.

Why is Piezo Direct the Best Choice?

Designing around a piezoelectric sensor can be extremely difficult at times, especially when considering the predetermined input and output operational ranges. Piezo Direct lets you work around that. Instead of designing an experiment around a sensor that only works between 1 and 20 atm of pressure, why not find a sensor that works between your experimental design? Our customizability is something that no other competitor can offer.
