Ultrasonic Transducer, Electrostatic & Piezoelectric

Click here to read more insights about ultrasonic sensors. For example, the electrostatic Smart Sensor measures 1.6 x 0.75 in., making it a compact solution in tight spaces (see Fig. 1 ). Piezoelectric transducers are a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge. When we squeeze this piezoelectric material or apply any force or pressure, the transducer converts this energy into voltage. This voltage is a function of the force or pressure applied to it. Senscomp Ultrasonic Sensors understands the costs and frustrations inherent in technology and its development.

Detection may occur in the uncertainty zone due to multi-reflection between the sensor and the object. If you do not receive a response from the seller within two business days, you can also claim a refund by contacting customer service. Cleared payment – opens in a new window or tab. Electrostatic transducers also have several disadvantages. One is that the operating element (metal-coated film) is more fragile that a closed-faced piezo sensor, making them less rugged. Also, housing materials are limited to various classes of steel.

A single electrostatic transducer coupled with the proper electronic driver and receiver can cover a range of 1 inch to over 40 feet, making them a good choice for deep tank level measurement applications. Electrostatics outperform piezoelectrics in all functional areas except for size and ruggedness. A single electrostatic transducer coupled with the proper electronic driver and receiver can cover a range of 1 in.

This can be attributed to its simplicity in terms of the components. There are no special materials required for it to operate. In application, the device has both a transmitter and receiver. These are designed to either be as close to each other as possible or are combined into a single module to reduce error margins. Otherwise, the recorded time taken will be inaccurate and this will result in a miscalculation of the distance.

Ever wondered how bats manage to find their way around even though they lack a comprehensive kind of vision?

The latter is more affected by the issue of energy dissipation hence the suitability for short-range applications. Sensor designers have successfully limited the frequency drift problem by using the unique drive and receive circuit designs. SensComp sells its products and services in the industrial & scientific category, mainly including temperature sensors, ultrasonic proximity sensors, and electronic component sensors. If you are looking for these products, SensComp can be your candidate. Automation – Manufacturing industries utilize the devices to automate various processes hence enhancing efficiency and productivity. A lot of robotics applications use these sensors to get the job done.

Two electrodes are then bonded to the crystal, and the crystal is then adhered inside a closed-face housing and sealed from the rear. The reflective efficiency varies depending on the shape of these objects. In the case of, the greatest amount of reflected waves return, however, this is strongly affected by the inclination of the object.

This further widens the range of its application because it suits a variety of conditions. By impulse driving rather than tone driving the transducer with a high voltage, short duration, and single cycle, the transducer resonates in a manner analogous to striking a bell with a hammer. The receive circuit is designed with a wider bandpass filter to accept the dynamic range of frequencies that are possible for the transducer over the specified temperature ranges. Piezo transducers are constructed using a ceramic piezo element that has been cut and tuned to a specific frequency range.
