The two principal pressure types are gauge (or gage) and absolute pressure. Vacuum is sometimes considered its own pressure type, although it is a negative gauge pressure. Barometric pressure is also used in discussions; it is the atmosphere’s absolute pressure. Differential pressure is also considered a pressure type, being the difference of two separate pressures. […]
The Pt100 temperature sensors are very common sensors in the process industry. This article discusses many useful and practical things to know about the Pt100 sensors. There’s information on RTD and PRT sensors, different Pt100 mechanical structures, temperature-resistance relationship, temperature coefficients, accuracy classes and on many more RTD Sensors The abbreviation RTD comes from “Resistance […]
Identify explosive and hazardous areas to use explosion-proof equipment and obtain relevant certifications. Explosion zones are gaseous environments that are classified according to the amount of gas available and how long they last in the environment. ZONE 0: It refers to the area in which the explosive atmosphere flows continuously or for a long time. […]
The name is derived from the first letters of the phrase Atmosphere Explosible in French. ATEX is the abbreviated name of the European Directive 2014/34 / EC on explosion-proof electrical and mechanical equipment, systems and components which over time became official laws in various countries. Therefore, the manufacturer is responsible for ensuring that each product […]
What is calibration? calibration is a comparison of two measurement devices against each other and the documentation of the comparison. The device to be calibrated is compared against a more accurate, traceable reference standard, often referred to as a calibrator. Why calibrate? It is pretty obvious that the fundamental reason for calibrating any process instrument […]
Pressure Sensor A pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal. A pressure sensor will generate a signal based on […]
Gas pressure reduction systems are needed in order to match the quality of the gas in the pipelines with the gas conditions required by the consumer. These specifications include the amount of gas flow, pressure and gas temperature which must be automatically controlled and recorded. Pressure Reducing Stations: City Gate Station (CGS) CGS stations are […]
Since 1950, with the increasing development of the industry, the need for advanced controllers has arisen. Disadvantages of control systems at the time, such as noise, the large number of control panels, and debugging, led to introducing “logic controllers” into the industry in the 1960s. These systems solved the problem of noise reduction and a […]
Temperature sensor As the name indicates, a temperature sensor is an instrument that can be used to measure temperature. It has an output signal proportional to the applied temperature. When the temperature of the sensor changes, the output will also change accordingly. There are various kinds of temperature sensors that have different output signals. Some […]
