Types of pressure measurements
DISPLACEMENT SENSOR APPLICATIONS Machine automation - these are extreme environments so the sensor must have the correct sealing to be suitable.
① Repeatability: The maximum difference between load cell output readings for repeated loadings under identical loading and environmental conditions.
② Resolution: The smallest change in mechanical input which produces a change in the output signal.
③ Sensitivity : The ratio of the change in output to the mechanical input.
① Load Cell: A device which produces an output signal proportional to the applied weight or force.
② Natural Frequency: The frequency of free oscillations under no--load load conditions.
③ Nonlinearity: The maximum deviation of the calibration curve from a straight line drawn between the no--load an
① Creep Recovery
The change in no--load output occurring with time after removal of A load which had been applied for a specific period of time. Usually measured over a specific time period immediately following removal of rated load and expressed as a percent of rated output over a specific period of time.
The change of length along the primary axis of the load cell between no--load and rated load conditions.
A random change in output under constant load conditions.
① Ambient Conditions
Humidity, pressure, temperature, etc. of the medium surrounding the load cell.
② Ambient Temperature
The temperature of the medium surrounding the load cell.
③ Angular Load Eccentric
A load applied eccentric with the primary axis at the point of application and at some angle with respect to the primary axis.
Application of wire displacement sensor Wire displacement sensor is a new type of distance sensor developed by principle using linear sensor. It consists of a potentiometer, a control circuit and a group of mechanical components.
How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.
The magnetostrictive linear displacement (liquid level) transmitter is mainly composed of a measuring rod, an electronic silo and a non-contact magnetic ring (floating ball) on the measuring rod. The measuring rod is equipped with magnetostriction wire (waveguide wire).
