Selecting A Wire
GENERAL CONSIDERATIONS Vinyl offers low Cost, good flexibility, fair electricals, a good general purpose material. Irradiated PVC offers moderate cost, heat resistance, good electrical and physical properties, excellent abrasion, cut-through and solder resistance. Teflon offers high cost, high temperature rating, excellent chemical resistance, excellent electrical properties, poor cut through resistance. Tefzel offers high cost, good […]
Selecting The Right Temperature Sensor
Imagine that you are an Instrumentation Engineer. You are looking at the prints for a new plant, and you see the many locations marked out for temperature transducers. You ask yourself; What has been specified to fill each space? RTD for their high accuracy and linearity? Or thermocouples because of their lower cost and familiarity? […]
Roller Bearings In Depth
A rolling-element bearing is a bearing which carries a load by placing round elements between the two pieces. The relative motion of the pieces causes the round elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground […]
Bearing Temperature
The stabilized operating temperature of a bearing is the result of many factors. The key influences on operational temperature are bearing style, lubrication type, operational factors, environmental conditions and level of maintenance The particular bearing style (ball, roller, sleeve, etc.), the shaft mounting style (slip fit, adapter mounted, press fit, etc.) and auxiliary items (housings, […]
