Listening to machine sounds with stethoscope ELS14
SPM Instrument now announces the introduction of a new version of its popular electronic stethoscope. Listening to machine sounds in order to determine the probable source of abnormal noise is one of the most widely used methods in maintenance departments across all branches of industry.

Machine faults manifest themselves in a variety of ways. One of the most widespread approaches for detecting mechanical problems is listening to the sound of the machine’s internal parts while they work. SPM’s new stethoscope ELS14 is a practical and easy-to-use electronic listening device that helps pinpoint the source of mechanical noise in a broad range of applications. It can also be used as a “second-opinion” tool to verify deteriorations detected with various measuring devices. Bearing condition, gear and pump noise and electric relay operation are just a few of the many sounds which can be identified, amplified and assessed.

Superior sensitivity and sound quality

The ELS14 stethoscope has superior sensitivity and exceptional sound quality. High, middle or low filters can be selected in order to single out relevant frequencies; with the push of a single button, the appropriate filter is applied. Volume is adjusted in the same simple way. Ear defenders effectively shut out ambient noise.

The battery-powered ELS14 stethoscope comes with an internal SD card and recording capabilities, enabling sounds to be played back from the device and also stored as sound files for further evaluation or future comparison.

Robust - yet lightweight – this one-hand operation stethoscope has an IP55 housing and is supplied with a durable carrying case and a set of two probes (60 and 290 mm long respectively). The internal thread is the same as in the predecessor ELS12, allowing continued use of existing probes.
