Machine condition monitoring is a practice where professionals regularly inspect a machine, device, or system for any indication of issues that might lead to an early failure. Thanks to state-of-the-art sensor technology and wireless transmission, even on-person machine condition monitoring inspections aren’t always required. In the world of the Industrial Internet, people don’t necessarily have to physically be present to get a good idea of what’s going on. Imagine safely monitoring a piece of equipment with ease through online condition monitoring without opening the gauge, removing the bolts, and assessing the components manually.
A common example of condition monitoring is an elevator. Elevators must undergo inspection, typically every year, to ensure the elevator is still safe to operate. Condition monitoring system tests are performed on several parts, including the drives, the machine room, and the escalator or elevator car.
A strain gauge transducer now is like a tiny sensor. Before it is installed, some wires are attached to it with their specific area that fits into another component that does the actual sensing. The wires act like sensors that help translate the mechanical energy of movement into something electrical. It has no moving parts and can be used in several applications, like condition monitoring vibration, force, strain, stress, displacement, acceleration, torque, or even speed and proximity! This is because it has no moving parts. A strain gauge can measure up to 5% in total strain or, in some cases, 0.25% displacement in one direction if you’re dealing with linear motion. They are highly accurate ways to measure force and pressure!
The complex design of industrial machinery makes it difficult to assess the condition of the internal components. A traditional approach would be to remove the bolts and assess the components manually. This method is not only time-consuming but causes downtime as well.
Here’s a much faster and convenient solution for you.
We provide advanced non-invasive monitoring systems designed exclusively to reveal the condition of machinery components by monitoring vibration, sound, and temperature signals while it’s operational. Being aware of what’s happening to your machinery during operation will allow you to fully utilize its runtime and plan subsequent services accordingly.

What are the various methods and devices for condition monitoring?
Conditional monitoring of machines is critical for asset utilization and safety. Some of the most common and widely used methods are:
Oil analysis: This method involves testing the lubricants and other fluids used in the machinery. As the machine trends toward wear and tear, the lubricating fluid collects contaminants and/or metal shavings, which indicate an impending failure. Some of the common techniques that are used are ferrography, Dielectric strength test, Sediment test, Ultraviolet spectroscopy, etc.
Vibration Analysis: This method involves recording and analyzing vibration patterns produced by a part that may be misaligned, out of balance or inherently flawed. Each part, such as a bearing, rotor or shaft, vibrates in a different way. And these unique patterns can be used to predict probable failures. Techniques used are: Fast fourier transforms, Time waveform analysis, Ultrasonic analysis, etc.
Thermography: This includes studying thermal patterns in machines to predict abnormal wear and tear or potential failures. The device used in this process picks up temperature differences to indicate misalignment, worn components, overheating and even improper lubrication. Techniques include Comparative thermography, Pulse thermometry, Lock-in thermometry, etc.
What are the advantages of condition monitoring?
As the name suggests, a condition monitoring system is a technique that helps monitor the condition of a system or equipment. Typically, a sensor is used to determine the status of a system. Condition monitoring means frequent measurement of a machine’s performance and parameters. Condition monitoring system enables us to prevent machine breakdowns. The condition monitoring system is considered one of the most important machinery maintenance. Several industries have already implemented condition monitoring systems. It can improve process capabilities, reduce costly downtime and improve machine reliability. It also helps in reducing product defects.
How do you use condition monitoring equipment?
To use condition monitoring equipment, you must know the difference between the common types of monitoring equipment. This will enable you to choose the correct tools for the correct application. There are two primary types of condition monitoring systems: a sensor and a recorder. The sensor is a device that monitors a physical quantity and sends a signal to a recorder when a change takes place. The sensor is usually designed to indicate a specific property, such as a specific conductivity, level, or pressure. The recorder continuously monitors a process and sends a signal to a graph when the process is out of spec. The recorder is usually designed to monitor a wide range of conditions and signal a warning alarm or a graph.
Where is a strain gauge used?
Strain gauges are used for manufacturing quality control. They measure the force applied to an object. They are used in structural engineering for monitoring stress-strain relationships in structures. A strain gauge is used to measure the torque or axial tension applied by a turbine, generator, engine, propeller or wheel. It is essentially an electric sensor that converts rotational force into electric signals to help you determine the crucial performance metrics of the machinery. They are also used in light switches, which use a light beam to detect strain in the switch’s mechanism.
How does a strain gauge pressure transducer work?
The basic principle behind a strain gauge pressure transducer is very simple. As pressure increases, a material stretches or deforms. In turn, this deformation changes the resistance of the material. In a strain gauge pressure transducer, a gauge is connected to a diaphragm inside a resistive element. When the pressure increases, the diaphragm is pushed closer to the resistive element, thus increasing the overall resistance of the strain gauge pressure transducer. The gauge’s resistance is then measured using an instrumentation amplifier, which converts it into an output voltage that an online condition monitoring can then read.
