Kinds Of Operational Amplifiers

There are various types of electrical and electronic components which are typically used to design electronics projects and circuits. These components include, operational amplifiers, integrated circuits, microcontrollers, microprocessors, digital logic gates, analog to digital or digital to analog converters, and so on. Let us consider operational amplifier, which can be defined as an electronic device which takes differential input and thereby generates a single ended output and is termed as a DC coupled high-gain electronic voltage amplifier. In this article, let us discuss about the op amp circuits and basics. Op Amp Circuit The operational amplifier can be used to […]

Calibrating a Guage using Deadweight Tester

Calibrating at the bench with a deadweight tester A deadweight tester (DWT) is a method of pressure calibration that is done in bench applications especially when accuracy and reliabilityis required. Calibrations are performed at the bench for convenience and to maintain reference conditions. Reference conditions are necessary to achieve the reference accuracy of the device under test and the calibration standards. Reference accuracy may be required to maintain the necessary test uncertainty ratios (TUR). To perform the test: The pressure gauge should be mounted in the same orientation (vertical or horizontal) as in the process. Measurement points should be distributed uniformly over […]

HART Smart Pressure Transmitter Calibration

How to calibrate a HART Smart Pressure Transmitter using The Fluke 754?   The accuracy and technology design of smart pressure measurement devices has totally improved in the past few year. Many old calibration instruments are unable to calibrate pressure transmitters nowadays due to  its high accuracy. Higher technologies are required in order to calibrate state od the art pressure transmitters.   Verifying the performance of a HART smart pressure transmitter as will as and adjusting it requires a number of tools. Performing all this is never been easier with a HART enabled calibrator like the Fluke 754. It simplifies the task and reduces the tools you need to carry.   Procedure: […]
