PROWAVE Ultrasonic Transmitter 40kHz - 14mm

The PROWAVE Ultrasonic Transmitter 40kHz is a high-performance open-type transducer designed for reliable ultrasonic sensing applications. Featuring a piezoelectric ceramic disc mounted at the node of its fundamental resonant frequency, this transmitter delivers consistent and accurate sound wave generation. The conical metal resonator, bonded at the centre of the disc, acts as a rigid piston, ensuring high sensitivity, wider bandwidth, and excellent durability across a broad range of temperatures and humidity levels. Its robust construction provides high stability in both electrical and mechanical characteristics, making it a dependable choice for demanding environments.

The open-type design allows free vibration, making this transmitter particularly suitable for continuous wave driving, such as in Doppler motion detectors. The aluminium housing ensures the unit is both compact and lightweight, facilitating easy integration into existing systems. With a 2kHz bandwidth and a 2400pF capacitance (at 1kHz ±20%), this transmitter delivers precise performance for a variety of sensing and measurement tasks.

Key Features:

• Aluminium housing for durability and lightweight design
