1.3051D transmitter is a coplanar pressure transmitter, which can measure the pressure or the side differential pressure, and there are two options P is the differential pressure measurement and G is the gauge pressure. 2. To understand the range used in the field, select the corresponding code according to the range, a total of 5 options: the lowest - 6.216KPA and the maximum 13789.54KPA. ...

1. When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer tube (coil), and the working temperature of the Rosemount transmitter should not exceed the limit. 2. When wiring, pass the cable through the waterproof joint or winding pipe and tighten the sealing nut to prevent rain from leaking through the cable.

Rosemount transmitter selection requires a good transmitter before use, so its selection is very important 1. According to the pressure interface mode Generally, threaded connection is the standard interface method. 2. According to the required accuracy level Measurement error of the transmitter ...

1. Look at whether the diaphragm is damaged, if not, after removing it, press it with chopsticks after imitating the power on in the room to see if there is a pressure display, if there is a display change, you can only disassemble another one, see if the transmitter module is broken, because the transmitter modules are integrated ...

The fundamental function of the Rosemount 644 temperature transmitter is to make serious improvements based on extensive user feedback and application sensitivity requirements in various industries. 1. Power terminal placement: Now the power supply and communication terminal are placed at the bottom right of the equipment, and the LCD can be carried out without removing the LCD.

1. The measurement is not affected by the change of fluid density, viscosity, temperature, pressure and conductivity. 2. There are no obstruction moving parts in the measuring pipe, no pressure loss, and the requirements for the straight pipe section are low. There is a common adaptability to slurry measurement. 3. Reasonable selection of sensor lining and electrode materials, ...

The following points should be considered in the selection of differential pressure transmitters: 1. Measure the scale, the accuracy of the demand and the measurement function; 2. Measure the environment of the outer surface, such as the industrial environment of petrochemical industry, the existence of flammable, toxic and explosive risk atmosphere, and the high ambient temperature; 3 tested ...

When a problem arises in the design of Rosemount thermowells, it is necessary to analyze the cause of its failure, and then go further and propose solutions. In some less complicated cases, it may be necessary to make a small change, such as adding one millimeter without changing the predetermined measurement orientation ...

Eight ways to use Rosemount pressure transmitters: 1. When measuring steam or other high-temperature media, it is necessary to connect a condenser such as a buffer tube (coil), and the working temperature of the Rosemount transmitter should not exceed the limit. 2. When wiring, pass the cable through the waterproof joint or wrap it around.

Rosemount transmitters are used in industrial process control and technical measurement processes, because the elastic and sensitive elements of mechanical pressure gauges have high mechanical strength and easy production, so that mechanical pressure gauges are more and more widely used. 　　Rosemont ...
