Instrument index is a document containing list of instrument devices within a process or plant. The instrument index will include the tag number of all physical objects (e.g. field instrument, visual alarm and indicator) and counterfeit tools commonly referred to as “soft markers” (e.g. DCS indicator, alarm, controller). The instrument index will be built at the …
To start and close the three-phase AC import motor, any three-stroke replacement at the appropriate current level will suffice. Just turning off such a switch to send three-phase power to the car will cause it to start, while turning on a three-stroke switch will reduce the power of the car to turn it off. If …

This document analyzes the differences between a standard transmitter and a smart transmitter that absorbs pressure, a different pressure transmitter, and an estimated temperature. Standard transmitter Conventional transmitters that offer 4-20 mA signal output in a two-wire connection, corresponding to 0-100% of the rated frequency range, have limited adjustment for various compression ranges. Performance varies …

The SMART transmitter represents a Single Modular Auto-based Remote Transducer. It is a smart transmitter with analog effect and simultaneously provides digital communication signal in accordance with the HART protocol or FOUNDATION FIELDBUS or PROFIBUS. Typically, a simplified drawing of a smart transfer is shown in the image below. Contains sensor or input circuits, microprocessor, …

Flow measurement based on the differential pressure principle (Orifice-Nozzle-Venturi). Some 300 years ago, Swiss mathematician and physicist Daniel Bernoulli discovered the direct relationship between the pressure and speed of a fluid flowing in a pipe. Italian physicist Giovanni Battista Venturi also performed experiments on flow and, in 1797, he built the first flowmeter for closed …
