Optimum Frequencies: 25kHz and 46kHz NTK test results available. Average: 45.449(kHz) 33(mS) 24.504(kHz) 10.5(mS) Measured Voltage: (AC V/m) 200 Admittance: (S) 0.030,0.035 Capacitance: (pF) 6000 Allowable input power: (W) 90. These are very powerful, reliable transducers which can be driven hard! Size 1.75" dia x 3.5" length. These are not immersible but can be easily attached to the outside of the fluid containers. Offers above $65 each in quantities considered.

This pre-assembled sensitive ultrasonic motion detector circuit uses a quartz crystal to lock the detector frequency for maximum stability and reliability. It was originally designed for use as a parking distance detector. It provides a digital, analog and relay output. Features; Buzzer output: fast/slow/continuous. Distance indication with 3-LED-bar. Adjustable alarm distance. LED alarm indicator. Dry contact NO/NC relay. Applications: robot projects, object detection, distance measuring, parking aid, security systems, etc. Range: 0.66 to 8 ft. Frequency 40kHz. Operates on 12VDC/200ma.

For professional use: jewellers, opticians, dental labs, dentists, doctors, printer head cleaning. For home use: jewellery, dentures, eyeglasses, cleaning the heads of electric shavers, etc... Stainless steel tank. 20 fl oz. capacity. Operates on 42kHz. 3 minute automatic shutoff. 110VAC/50watt. External size 8" x 5" x 5-1/2". Internal size 6" x 3-1/2" x 2-1/2". RoHS compliant.

Point the laser beam and presto, ultrasonics calculate the distance. Also calculates the area and the volume. 3' to 60' range. 0.5% accuracy. Big 1/2" LCD readout.
