Portable Vibration Meter (Accelerometer)
Part Number M81101
The Mechanalysis model MIL811 plays a dual role in
machinery maintenance: - It is used for periodic vibration
checks for unbalance, misalignment, looseness, etc.
With an industry standard high frequency detection
circuit, it pinpoints incipient bearing and gear deterioration.
Its solid-state circuitry provides wide dynamic range
and long battery life. From precision bearing inspection
to plant-wide maintenance, the MIL811 has the sensitivity
for measuring fractions of a micrometer to 3000 micrometers
with 8 easy to read overlapping ranges.
The MIL811 also includes the widely acclaimed IRD
Spike energy circuit. The broadband measurement of
Spike Energy (units of gSETM) has proved
to have the advantage of simplicity and earlier warning
of bearing and gear defects.
By detecting and measuring “bursts” of
spike energy at ultrasonic frequencies, defects such
as micro spalls and cracks and lack of lubrication
can be quickly identified.
