	AVC Technology in Weighing applications
	- Active Vibration Compensation (AVC) Technology - Weighing in surroundings with vibrations and interfaces - In every kind of production there can be types of interfaces which can influence the exactness of weighing results .....

	Cable Considerations
	By nature, cables are the weakest point of any measurment system....

	Charge Mode Accelerometers
	Dytran charge mode accelerometers are designed to measure shock and vibration phenomena over a broad temperature range. These accelerometers contain no built-in amplifiers. Dytran

	Draw Wire Operating Principle
	WS Sensors capture position measurement either absolutely or incrementally using measuring cables made from stainless steel....

	Eddy Current Probes Theory of Operation
	Eddy-Current probes are non-contact devices capable of high-resolution measurement of the postion and/or change of position of any conductive target.

	Evolution of Torque Sensors
	The historical evolution of torque measurement technology begins...

	FAQ for DMS Displacement Sensor Display
	What menu functions can be accessed with the 4 keypads on the DMS? Can we display displacement in engineering units? What readouts are available from the DMS display? Where can we find DMS instruction manual? Can DMS data ...........

	Fiber Optic Displacement Sensors In Fluids
	The target to be measured is submerged in a fluid. How can accurate displacement measurements be made using Philtec's fiberoptic sensor? The responce of the sensor in a fluid is different that the sensor's responce in air. Therefore, sensor .............
