Strain sensitivity of a piezoelectric sensor is 5V/µƐ.These sensors have very low Soldering temperature.These sensors are to be kept at a temperature between -30☌ to +70☌ to prevent them from degradation.These sensors generally operate in a temperature range of approximately -20☌ to +60☌.These sensors contain as Impedance value ≤500Ω.Reliability: This accounts to the sensors ability to keep characteristics in certain limits under set operational conditions.īesides these, some of the specifications of piezoelectric sensors are a threshold of reaction, errors, time of indication etc….Sensitivity S: Ratio of change in output signal ∆y to the signal that caused the change ∆x.The range of measurement: This range is subject to measurement limits.
Some of the basic characteristics of piezoelectric sensors are Piezoelectric Sensor Piezoelectric Sensor Specifications Sensors are also known as primary transducers. A sensor can be called a pressure transducer in an electrical signal. For the proper response of the sensor, the load and leakage resistance must be large enough so that low frequencies are preserved. The capacitance Ce is inversely proportional to the elasticity of the sensor material. The inductance is due to the inertia of the sensor. The resistance Ri is the internal resistance or insulator resistance. Piezoelectric Sensor CircuitĪ piezoelectric sensor internal circuit is given above. The piezoelectric material generates charge used for calibration of motion.Īn acceleration compensation element is used along with a pressure sensor as these sensors can pick up unwanted vibrations and show false readings. When motion is applied, seismic mass load’s the piezoelectric material according to Newton’s second law of motion. In accelerometers, seismic mass is attached to the crystal element to transfer the applied force to piezoelectric materials. The produced voltage is proportional to the amount of pressure applied. Upon application of pressure on this thin membrane, the piezoelectric material gets loaded and starts generating electrical voltages. It does not store any personal data.In the pressure sensor, a thin membrane is placed on a massive base to transfer the applied force to the piezoelectric element.

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. Piezo sensors can be manufactured in a variety of shapes and sizes, including piezo disc, piezoelectric tube, piezo ring, and other custom piezo elements.ĭesigning around a piezoelectric sensor can be extremely difficult at times, especially when considering the predetermined input and output operational ranges. This, combined with very linear input/output relationships, makes piezoelectrics invaluable to laboratory settings. Piezoelectric sensors have many other benefits as well: highly customizable shape, wide operational ranges, extreme responsiveness, etc. temperature, magnetic fields) and thus hold high value in collecting extreme data, such as those in explosions. Piezoelectric materials stay operational within a very large range of conditions (i.e. Why would you use a Piezoelectric Sensor? More details regarding the mechanics can be found here. The latter only send signals when they receive inputs and do not do anything otherwise, hence the name. Information regarding distance and depth can be obtained when analyzing the delay. The former sends ultrasonic signals and waits for a response, after which it releases an electrical signal. Piezoelectric sensors are piezo elements that convert environmental conditions into readable and usable electrical signals.
