Proper use of a pressure sensor process shall consider the following: 1, to prevent contact with the transmitter and the corrosive medium or hot; 2, to prevent garbage deposited in the conduit; 3, when measuring the liquid pressure, the pressure taps should be opened in the process side of the line imported MCT404, in order to avoid precipitate slag accumulation; 4, when measuring the gas pressure, the pressure taps should be opened at the top of the flow line, and the transmitter should be installed in the upper part of the flow line to be easily injected fluid accumulation in the flow line; 5, the guide pressure pipe should be installed in a small temperature fluctuations place; 6, the measurement of steam or other high temperature media, must be connected to add a buffer tube (coil), and other handheld condenser MCT404 original, not make work transmitters temperature exceeds the limit; 7, when winter frost occurs, the transmitter is installed outdoors freezing measures must be taken to prevent the liquid inside the mouth due to the impulse ice volume expansion, leading to the sensor is damaged; 8, measurement of liquid pressure transmitter The installation location should avoid the impact of the liquid (water hammer phenomenon) MCT404, so as not to damage the sensor overvoltage; 9, the wiring, the cables through the waterproof connector (accessory) or about the nature pipe and tighten the nut tightly sealed to prevent rainwater through cable leakage into the inner transmitter housing. The main effect of the pressure transmitter pressure signals to the electronic device, and then the computer shows the pressure principle generally: the mechanical signal into a current pressure of this pressure (4-20mA) such electronic signal pressure and voltage or double the current size of a linear relationship agreement MCT404 Communicator, generally proportional relationship. Therefore, the output voltage or current transducer with pressure increases thereby obtain a two pressure measured media pressure and voltage or current relationship through the high pressure transmitter, two low pressure chamber , low-pressure chamber pressure with atmospheric pressure or vacuum acting on the δ yuan (ie sensitive element) on both sides of diaphragm, transferred to a measurement on both sides of the diaphragm and filling liquid through the spacer element within. MCT404 Communicator original, MCT404, China-Technology provided by the Jinan-Technology Co., Ltd. Jinan Huahui Technology Co., Ltd. (www.cnhuahui.com/) strong, credible, in Jinan, Shandong pressure instrumentation industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead China-Technology into the brilliant and you work for a better future!
