The term shaft power meter refers to a digital system for measuring that makes use of a laser beam in order to detect shaft torque, shaft RPM and as a consequence of this, it also detects the transferred power. The greatest thing about these systems is the fact that they can offer long term stability and high accuracy.

Some of the best shaft power meters rely on vibrating string transducers that are attached to a pair of clamp rings. The whole idea is to create harmonic pulses that will in turn make sure that the resonant vibration of the strings will remain an ongoing process. However, that process must be in complete accordance with the shaft torque. If you are interested in more information on the relationship between the power and the torque, you can read about it here.

The technology of the best and most reliable shaft power meters should include double transducers that serve for system supervision and compensation of failure. If the most accurate performance is what you have in mind, look for a shaft power meter that has touch screen display and the option for having analog and digital input signals integrated as an upgrade.

The figures being measured with theses meters are shown on analogue instruments or in digital form through the usage of Liquid Crystal Display monitor.

The Key Features of a Shaft Power Meter

• Very accurate and reliable type of measurement

• Compensation for effects caused by various environmental factors (shaft bending, temperature)

• System based on self-supervision, provided by the usage of vibrating string transducers

• Transducers are not attached to the shaft; they are fixed to clamp rings to achieve easier dismounting

• The exchange of power occurs between the shaft and the transmission unit

• The shaft power meter is easy to maintain and the calibration is conducted by crew

• Touch screen display

Once you become familiar with the basics of shaft power meters, you will certainly realize that they can be money and time saving tool. The pumps and all other applications will be well taken care of and the inefficiencies of the processes will be detected on time. You also might want to look for a shaft power meter that offers measuring the shaft power output. This is conducted by using the motor as a sensor. Through the usage of these meters the installation and maintenance costs are diminished and the life span of the equipment increases significantly. Getting a meter that uses a monitor with unique techniques for monitoring motor shaft power will lead to linear and accurate motor load value.
