How to Measure The Dynamic Output of Heavy Machines

Posted by eliteinternet on November 11th, 2019

It is important to use the correct type of accelerometer for a specific purpose based on the requirement and space available for the device.

In order to detect the machine vibration of any device, you need a measuring instrument that can accurately measure its change in speed with respect to time, and such devices are called accelerometers. Today, accelerometers can be found in most devices, be it mobile phones, laptops, wrist watches, automobiles, or across the aerospace sector and heavy machineindustries. Typically, industrial accelerometers are handy and can be mounted easily to gather information about the system. 

To detect the orientation and magnitude of the system, devices are fitted with the accelerometer which measures their changing speed over time; this technology is extensively used in the aerospace and maritime industries where navigation and acceleration are monitored through electronic systems. They accumulate accurate data, offering a quickresponse to avoid any mishap.

Beyond these large industries, various types of accelerometers find their profound application in fans, motors, pumps, machine tooling, compressors, centrifuges, spindles, cooling, HVAC, conveyors, air handlers, gearboxes, rolls, dryers, presses, process equipment, and many more.

Let us take a look at different types of accelerometers used in industries:

Standard Accelerometer: These are widely used in rotating machinery applications. Their general purpose is to collect data, analyze, and system protection. They have 2 pin MS Connector and are made up of stainless steel with operating temperature ranging from -67 to +302°F (-55 to +150°C).

Integral Cable Accelerometer: This device is cost-effective and designed with a waterproof shield protected by an epoxy filled stainless steel case. They are available in the market with top exit or side exit cable for easy mounting purposes. 

Compact Accelerometer:  This is an advanced, mini version of Standard Accelerometers. These light-weight devices can be mounted in extremely compact spaces and are responsive to any frequency. You could also use extended cables for highly complicated system designs. 

Dual Output Accelerometer:  The part makes use of 3-Pin MS Connector to give dual output that is standard 100 Mv/g vibrations as well as a 10 mV/°C temperature signal.

Biaxial/Triaxial Accelerometer:  Triaxial are built in a 3-D form with three accelerometers mounted 90 perpendicular to each other to give output in 3 perpendicular planes (X, Y, Z). They use a multi-pin connector, whereas, biaxial give output in only two directions. Moreover, they are generally available with just a side exit due to their complex design. 

Piezo Velocity Transducer: This is a type of accelerometer that gives velocity as an output. They work on a principle of piezoelectricity based on their response to any kind of compression. Their application can be found in turbines, axial compressors, and much more.
