How to select a Rosemount 3051 transmitter?

Thread Content

Keywords of this article: Rosemount 3051. http://www.qyyb.net/ There is a high demand in the market for Rosemount 3051 transmitters. Rosemount has gradually made its way into various industries. So, how should we select the right model when purchasing Rosemount products? Below, I’d like to introduce some points to note when making a selection: Signal output: Generally, there are many types of output signals for Rosemount 3051 series pressure transmitters. The main ones are 4–20 mA and 0–20 mA, which use a two-wire system; all other types utilize a three-wire system. In fact, the main types of signal outputs are mV, V, mA, as well as frequency and digital outputs. The choice of output type depends on various factors in the production process, such as the distance between Rosemount 3051 series transmitters and system controllers or displays, whether there is significant noise and vibration, and whether there are any electronic interference signals present. Excitation voltage: The type of output signal determines which excitation voltage should be selected. Many amplifiers have built-in voltage regulators; therefore, they have a wide power supply voltage range. Some Rosemount 3051 series transmitters are specifically configured for certain applications and require a stable operating voltage. Therefore, the availability of such a voltage determines whether a transmitter with a regulator can be used. When selecting a Rosemount 3051 series transmitter, both the operating voltage and the overall system cost must be taken into account. Pressure medium: What we need to consider is the medium measured by the Rosemount 3051 pressure transmitter. Viscous liquids and slurries can clog the pressure ports; solvents or corrosive substances might damage the materials in the transmitter that come into direct contact with these media. Pressure range: To determine the maximum pressure to be measured in the system, it is generally necessary to select a Rosemount 3051 series transmitter with a pressure range that is about 1.5 times greater than this maximum value. Therefore, when selecting Rosemount 3051 series transmitters, the pressure range, accuracy, and stability must be taken into full consideration. Temperature range: A Rosemount Series 3051 transmitter is typically calibrated for two temperature ranges: the temperature range for normal operation and the range over which temperature compensation can be applied. Accuracy class: Factors that determine the accuracy of the Rosemount 3051 transmitter include non-linearity, hysteresis, non-repeatability, temperature, zero offset scaling, and the effect of temperature. However, it is mainly characterized by non-linearity, hysteresis, and non-repeatability; the higher the precision, the higher the price. Interchangeability: The selected Rosemount 3051 transmitter should be capable of being used in multiple production stages, thereby reducing costs for the company and improving production efficiency.
