Statement List (STL) to Find Highest Value

This article explains the detail logic and all steps involved to find the Highest value in given Data block using the Statement List (STL). Also helps to you in array…

Differential Pressure Sensor with Pair of Strain Gauges

The following differential pressure sensor uses a matched pair of strain gauges. As the differential pressure increases, one strain gauge becomes compressed while the other becomes stretched. A voltmeter registers…

Why Strain Gauge Resistance Changes as it Stretches and Shrinks?

A strain gauge is a device used to measure the strain (compression or expansion) of a solid object by producing a resistance change proportional to the amount of strain. As…

Communication between Factory IO and Siemens Tia Portal

This article is about communication between Siemens TIA PORTAL and Factory IO. You can use actual PLC to check your logic. You can also create an animation as per your…

Something is Wrong with Strain Gauge Bridge Circuit

A strain gauge is an array constructed from thin metal film designed to increase resistance as it is stretched and decrease resistance as it is compressed. Strain gauges are typically…

How a Bourdon Tube Pressure Gauge might be Adjusted for Linearity?

A pressure gauge is supposed to accurately indicate applied pressure over its full calibrated range. Bourdon Tube Pressure Gauge In this example, a gauge with a range of 0 to…

What is the Purpose of Bourdon Tube Gauge Spiral Spring?

Some bourdon tube gauges are equipped with a very small spiral spring attached to the pointer shaft: Bourdon Tube Gauge Now, this spring is much too weak to have any…

How to Decrease Span of Pressure Gauge?

Suppose a pressure gauge uses a diaphragm as its pressure-sensing element, like this:  Pressure Gauge This mechanism will work, but what if we desired to make it more sensitive? That…

Simulate Different Values for Pressure Instrument Under Test

One challenge technicians face when calibrating low-pressure instruments is how to generate very low air pressures to simulate different low-pressure conditions for the pressure instrument under test. Measuring low pressures…

Why Pressure Vessel Connected to Tubing System?

A very useful principle in physics is the Ideal Gas Law, so called because it relates pressure, volume, molecular quantity, and temperature of an ideal gas together in one neat…
