<p>Enclosed transducers that may be hermetically sealed and thus are suitable for outdoor use as well as for use in dusty and contaminated indoor environments. The transmitters and receivers are of the pulse transit type and consist of an aluminium housing with an integral diaphragm, the transducers resonating at the the first harmonic. The backs of the housing are completely sealed with resin, protecting them from exposure to the environment.<br/><br/>
Suitable applications for these devices include: paper feeding detector, sensor for counting devices, flow measurements, presence detectors, remote control devices, solid and liquid level measurements, intrusion alarms, energy management systems.</p>
Available in a choice of diameters in transmitter and receiver
Low cost
One piece solid metal case
High sensitivity and sound pressure level
Complete seal meets IP67
Note: Although the devices are constructed to be watertight, they are not recommended for use under water.
