The following schematic diagrams show the relative effects of 2 ohms total wire resistance on a RTD circuit: Clearly, wire resistance is more problematic for low-resistance RTDs . In the RTD circuit, wire resistance counts for 1.96% of the total circuit resistance. we can eliminate...

This utilizes the fact that Oxygen is a paramagnetic gas which distinguishes oxygen from other gases because it is attracted into a strong magnetic field. Basically when a gas sample is introduce to the instrument the oxygen will be drawn into the magnetic field resulting in a...

There are two different types of Zirconia measurement systems. 1 amperometric 2 potentiometric Figure shows a schematic of the amperometric system. An amperometric sensor consists of zirconia cell that has a high voltage being applied across the two platinum electrodes. Oxygen then flows through ...

The motion and power transmitted by gear is kinematically equivalent to that transmitted by friction wheel. Consider two circular wheels A & B mounted on two parallel shafts and the wheels are pressed against each other. Shafts are mounted on anti-friction bearings. When...

Steam trap is a type of automatic valve that filters out condensate (i.e. condensed steam) and non-condensable gases such as air without letting steam escape. If condensate is not drained immediately or trapped from the system, it reduces operating efficiency by slowing the heat transfer...
