Calibration and Preventative Maintenance Calibration: A comparison of two instruments or measuring devices one of which is a standard of
Differential pressure developed by a venturi, orifice plate, pitot tube, or any other flow element is proportional to the square-root of flow rate.
Proper connections for all three types of RTD sensor (2-wire, 3-wire, and 4-wire) to a user configurable transmitter are shown
A variation on the theme of echo-based level instruments, where the level of some process material in a vessel is
Radar level instruments measure the distance from the transmitter (located at some high point) to the surface of a process
RTD Standards A resistance temperature detector or platinum resistance thermometer works on the principle that the electrical resistance of a
Through measurement, we try to obtain the value of an unknown parameter. However this measured value cannot be the actual
4-wire “passive” versus “active” output transmitters Some self-powered (4-wire) analog electronic transmitters are designed to behave as electrical loads rather
