Rosemount transmitter is a kind of general pressure transmitter. It is manufactured according to the law of electromagnetic induction and JB/T9248-1999 standard. It is used to measure the volume flow of conductive liquid in pipes, such as water, sewage, mud, mineral slurry, acid, alkali, salt liquid and food slurry. Rosemount wireless transmitters are empowered with wireless HART protocol, and provide accurate level, pressure, and flow measurements. These transmitters can detect malfunctions of equipment, and help reduce equipment failures.

Simply stated, Rosemount temperature transmitter is electrical instrument that interfaces the temperature sensor to insulate, amplify, filter noise, and translates the signal from the sensor to the control unit. Temperature transmitters consist of a sensor and a transmitter, all of which affect the final output to the display panel. Temperature transmitters may be manufactured as stand-alone devices that are connected or inserted into the attachment head of a part to one or more temperature monitors in a process control system.

Yokogawa Electric Corporation was founded in 1915 and is headquartered in Tokyo, Japan. It has 80 subsidiaries in 54 countries and regions around the world. The business field involves three major fields of measurement, control and information. In the industrial control industry, it is one of the most professional multinational companies in the world.

Honeywell International, Inc. is a diversified manufacturing technology leader serving customers around the world, including aerospace products and services, industrial and home building control technologies, automotive products, turbochargers and specialty materials. Honeywell has 116,000 employees in more than 100 countries around the world to satisfy customers and strive to become the world's pioneer in automation, so as to achieve the goal of mutually beneficial growth.

ABB is a leader in power and automation technology. ABB's technology can help power, utilities and industrial customers improve performance while reducing environmental impact. The ABB Group has operations in more than 100 countries around the world, with 130,000 employees and 2010 sales of US$32 billion.

E+H flowmeter can be either mechanical or pressure-based, and employ different techniques for measurement. e h flow meter are used for measuring water supply to houses, as well as for commercial usage, and are thus necessary for individual consumers and business enterprises.

Fisher is elusive, forest-dwelling members of the weasel family with long, slim bodies, short legs, rounded ears and bushy tails. Fishers are larger and darker than martens and have thick fur. Fishers are agile, swift and excellent climbers, with the ability to turn their back feet nearly 180 degrees allowing them to climb head-first down trees.

Yield to call (YTC) is a financial term that refers to the return a bondholder receives if the bond is held until the call date, which occurs sometime before it reaches maturity. This number can be mathematically calculated as the compound interest rate at which the present value of a bond's future coupon payments and call price is equal to the current market price of the bond. Yield to call applies to callable bonds, which are debt instruments that let bond investors redeem the bonds—or the bond issuer to repurchase them—on what is known as the call date, at a price known as the call price. By definition, the call date of a bond chronologically occurs before the maturity date.

Siemens is a global powerhouse focusing on the areas of electrification, automation and digitalization. One of the world’s largest producers of energy-efficient, resource-saving technologies, Siemens is a leading supplier of systems for power generation and transmission as well as medical diagnosis.

The development of DCS/PLC from On-off control to sequential control and transportation processing is from bottom to top. Continuous PID control and other functions, PID is in the interruption station. A DCS/PLC can be used as a master station, and multiple DCSs/PLCs of the same type can be used as slave stations. PLC grid can be used as an independent DCS or a subsystem of DCS.
