Process calibrators are handheld, battery-powered instruments used for field testing and calibration of industrial process equipment. The typical calibrator has a one or two-parameter digital display, function switch and up/down buttons for output level adjustment.
An instrumentation Current Transformer (CT) is used to step down AC current to a level that can be more easily measured by a panel meter or test instrument. The amount of step down is specified by the CT ratio (e.g.
The Current Transformer (CT) is used to sense AC current in single-phase or three-phase circuits. In the basic instrument-grade current transformer, a single primary conductor passes through the core. The secondary winding has multiple turns to provide a lower output current,
Digital panel meters (or DPM) typically uses either an LCD (Liquid Crystal Display) or LED (Light-Emitting Diodes) to display information in an alphanumerical format. What are the differences between LCD’s and LED’s and how do you know which one to pick for your application?
Taut-Band Suspension System vs Pivot and Jewel Mechanisms
The frictionless, shock-proof, taut-band suspension system has demonstrated superiority over the pivot-and-jewel mechanism in all types of analog panel meters.
