Basic understanding of Pressure

What is Pressure? Pressure, flow, level, and temperature are the four common plant measurements. Of the four, the pressure is the most fundamental and common. The three remaining measurements can be inferred from pressure-flow (orifice plates, pitot tube, venturi), temperature (pressure thermometer), and level (hydrostatic ‘Head’ pressure). Also can be used to infer density (pressure for a given volume) and weight (load …

YS1700 Function Block Programming

Convert Yokogawa YS1700 Text Program to Function Block

I almost can’t trace back when the Yokogawa YS1700 launched, but based on the YS1700 successor the Yokogawa YS170 was discontinued in 2008. Therefore we assume the Yokogawa YS1700 began since 2008. This new controller upgrades with several features, for instance, the new LCD, shorter body length, 1000 steps text Program and 400 modules of …

3 main types of Pressure Sensors

There are many types of Electrical and Mechanical Sensors in the market. Still, all pressure sensor infer pressure by measuring a physical change within the sensor when exposed to pressure changes. This physical change can be resistance, capacitance, or frequency. Here would like to review all types of Pressure Sensors used with industrial pressure transmitters, explain of the sensor, hence advantages, and …

Grounding Ring vs Grounding Electrode, which one to use?

For any magnetic flowmeter to function correctly, it must have three connections (including a ground) to the process liquid passed from the magnetic flow tube onto the magnetic flow transmitter. About 80 percent of the time, problems with the flow measurement readings provided by a magnetic flowmeter can be traced directly to improper solution ground …

Differential Pressure Level Transmitter on Pressurized Tank

The difference from the atmospheric tank, the pressurised tank is an enclosed container in which has vapour pressure apply over the liquid and the value of the vapour pressure may vary along the time. Since the vapour pressure can not be neglected therefore, it should be measured by both pressure inlets of DP level transmitter. …

Level Calculation for Diaphragm Seal Transmitter

Another installation method for level measurement using a Differential Pressure level transmitter is by utilizing the diaphragm seal plus capillary tube. To determine the calibrated range for Differential Pressure level transmitter, the filling fluid density within the capillary must be taken into account in the calculation since the fill fluid also creates hydrostatic force exerting …

5 Types of Temperature Element

There are several temperature element types widely used to measure the temperature of a process substance. These types are categorized into mechanical temperature element and electronic temperature element. Mechanical temperature element uses the principle of thermal expansion, i.e. the element expands if the temperature rise and vice versa. Electronic temperature element uses the principle of …

Why using a Temperature Transmitter?

In the temperature measurement system, an electronic temperature instrument needs to connect to a control system. In contrast, RTD and thermocouple can be directly wired to the control system inputs card or via Temperature Transmitter for signal conversion. Most of the applications, the temperature transmitter are used to convert thermocouple or RTD signal into 4~20mA …
