The Beha-Amprobe ULD-400-RE Receiver is an ultrasonic detector that can be used to pinpoint the source of leaks, vibration or electrical discharge in HVAC/R, mechanical and electrical systems. Please see the following video for a quick introduction to Beha-Amprobe ULD-400-EUR Series of Ultrasonic Leak Detectors.
The Beha-Amprobe ULD-400-RE Receiver converts ultrasonic sound emitted by equipment failure into a visual and audible signal that can be used to locate the fault. The ultrasonic signal’s strength is indicated via a bar graph on the Beha-Amprobe ULD-400-RE Receiver’s LCD 6.35cm display. The user can also trace the source of the leak by listening to the converted audible sound via the headphones. Additionally, using the headphones the operator is able to identify the type of fault detected: air leaks issue a hissing sound while electric discharge creates a ticking noise. Please see the video below for a brief overview of how to use the Beha-Amprobe ULD-400-RE Receiver.
The Beha-Amprobe ULD-400-RE Receiver has a frequency range of 20kHz to 90kHz enabling it to detect a variety of leaks. The Beha-Amprobe ULD-400-RE Receiver also features adjustable sensitivity and is equipped with a filter function for removing up to three main noise frequencies, allowing the user to find faults in noisy environments. Please see the following video for further information.
Further to this, the Beha-Amprobe ULD-400-RE Receiver is compatible with a range of accessories and tools designed to improve the precision and ease with which faults and leaks can be detected. A parabola accessory (NOT included) works to direct ultrasound towards the sensor while a detachable tubular extension (NOT included) provides access to hard to reach areas. Additionally, the Beha-Amprobe ULD-400-RE Receiver can be used with the Beha-Amprobe ULD-400-TE Transmitter (NOT included) to find leaks in unpressurised systems; the transmitter boosts the ultrasonic signal allowing the receiver to find the source of the fault.
