As the name suggests differential pressure transmitter smart import, transmitters contain "change" and "send" means. The so-called "change" refers to the various physical quantities from the sensors, converted into an electrical signal. For example: the use of a thermocouple Honeywell differential pressure transmitter, the temperature was converted to an electrical potential; the use of a current transformer, the large current into a small current. Since the electrical signal easiest to deal with the principle of differential pressure transmitter, so modern transmitter, all the physical signals into electrical signals. Therefore, we say transmitters, usually becomes a "power." The so-called "free" refers to a variety of signals has become, in order to facilitate other instruments or control devices to receive and transmit, and again through the electronic circuit, the sensor signals to the differential pressure transmitter and unification (such as 4-20MA). The method is achieved by a plurality of operational amplifiers. This "change" + "send" on the formation of the modern most common transmitter. MV3000 Smart Multivariable Transmitter is a microprocessor-based smart transmitter. R300 latest version, to enhance the accuracy, reliability and long-term stability of the indicators of the transmitter. At the same time it was detected by the temperature, pressure (absolute or gauge pressure), and differential pressure the three process variables, according to the industry standard method of calculating the fourth draw process variables (mass flow or volume flow rate), and outputs the corresponding 4 ~ 20mA analog and digital signals. Its unique temperature and hydrostatic automatic error correction function so that it can meet the demanding environments. Having a DE protocol, with Honeywell's ExperionPKSTM distributed control systems and intelligent Field Communicator (SFC) two-way digital communication, eliminating the analog signal transmission errors, to facilitate the commissioning, calibration and troubleshooting the transmitter. Differential pressure transmitter differential pressure transmitter Honeywell _ _ Honeywell provided by the Jinan-Technology Co., Ltd. Jinan Huahui Technology Co., Ltd.
