Photonis USA - 3020701 - 99971SOCN7590416P6 - Radio Frequency Amplifier, Subassembly Tube. Part of AM-6412/APS-120.

An electronic device whose radio frequency input signals control power from a source independent of the input signals, and delivers radio frequency output signals of greater amplitude with respect to current and/or voltage. The output signals characteristics are uniformly related to the input signals. It operates at frequencies above 20 kilohertz.

Commercial Ultrasonic / Audio Transmitter & Receiver Probe

Transducer Receiver consist of a piezoelectric ceramic disc mounted with-in a probe.  A conical metal resonator bonded at the center of disc acting as a rigid piston. This special construction provides high sensitivity, wider bandwidth and excellent durability in wide temperature and humidity ranges and high stability in electrical and mechanical characteristics. Due to its free vibration character the open type transducers are very suitable for continual wave driving, such as Doppler motion detector.

High Quality Distance Ultrasonic Sensor Head
