Vibe - Vibration Detector
Low frequency vibration
increase indicates system imbalance. The area of detection (0.6 - 2.7g up to 300Hz) can
indicate instability in process systems such as water hammer, loss or wear of damper
mechanisms or shock absorbers, change from laminar to turbulent flow, loss of load,
overdriving engines, compressors, generators, etc.
Any
industry employing transport devices such as cranes or conveyors, screen or shaker
equipment, as well as all aspects of power generation, motors, pumps, turbines,
compressors, or other moving equipment has potential for applications of Dr. Vibe.

Cool - Temperature Loss Detector
Temperature
loss indicates loss of heating, system blockage or breakdown. In the range -25°C to
+85°C a decrease can indicate faults in hot water supplies, oil coolers, air conditioning
outlets, exhaust venting systems, chimneys, process control system failure, lubricant pump
breakdown, etc.
Any industry dependent
on steady state heating as part of its process can benefit from using independent
monitoring equipment.

Flow - Fluid Flow Verifier
Detection of liquid flow
in pipes is an important independent measurement to verify control gear such as valves and
pumps are operating correctly upstream. These modules are designed to operate in the audio
spectrum and therefore detect audible 'trickles' caused by irregularities in the pipe
system. The noisier areas of tubing are generally downstream from unions, joints, valves
or even bends.
Any flow that is
turbulent or partially filled also has good monitoring characteristics for this sensing
method. Flows from as little as those found in 12mm piping in domestic hot water supplies
can be monitored. Installation of 'Dr Flow' is particularly simple on pipes by using hose
clips or ty-wraps

Dr.
Heat - Temperature Rise Detector
Temperature rise often
indicates loss of system control or impending failure. In the range -25°C to +85°C an
increase could indicate loss of refrigerant, poor lubrication in gearboxes and bearings,
temperature control systems failure, heat exchanger or heat pump faults, electrical
switchgear breakdown, etc.
There are a wide range
of uses in all aspects of process industries; any small process plant could benefit from
the simple application of these devices. Food industry and cold storage in particular, are
provided with a completely independent means of monitoring potential catastrophe.

Knock - Mechanical Noise Detector
Use to detect impulse noise from mechanical sources such as
loosening of nuts and bolts, excessive 'chatter', water hammer, cavitation in pumps,
mechanical tapping, loss of lubrication, nucleate boiling, irregular fluid flow, resonance
of rotating machinery, worn brake shoes and discs, solenoid valve actuation, etc.
Applies to all
industries with mechanical components as part of their process. Also applies to pipe work
systems where water hammer is a problem.

Dr.
Rumble - Cyclic Wear Detection
Use for early detection
of wear in bearings or other rotating machinery.Using the high frequency noise
characteristics which bearings exhibit, and examining their low frequency components, wear
can be detected well in advance of failure or 'running rough'.
The characteristics of
classic ovoid wear are found throughout industries such as automotive, marine, power
engineering, conveyor systems, rolling mills, paper and pulp production, aerospace, mining
and quarrying, etc

Sonic - Audible Noise Detection
Audible noise is a
reliable indicator in various systems where other parameters are not available. For
example, the downstream detection of flow in an air conditioning system can often be heard
before any temperature or humidity change, and where actual flow measurement of low
density fluid is difficult. Similarly the 'buzz' of a transformer is one of the few
indications outside of its electrical operation that can be detected.
As 'Dr Sonic' deals
specifically with acoustic ranges then any signal we can hear is a reasonable candidate to
be detected with this unit. Applications and industries are widespread!
