• Response Time: This indicates how quickly the transmitter responds to changes in pressure. A fast response time is crucial in applications where pressure fluctuations need to be monitored in real-time. The 3051S has a typical response time of less than 100 milliseconds.

Functional Specifications

• Measurement Range: The measurement range specifies the minimum and maximum pressures that the transmitter can measure. The Rosemount 3051S is available in a variety of ranges to suit different applications. For example, you might choose a range of 0 to 100 psi for a low-pressure application or 0 to 10,000 psi for a high-pressure application.
• Overpressure Limit: This is the maximum pressure that the transmitter can withstand without being damaged. It's important to ensure that the overpressure limit is higher than the maximum pressure that the transmitter is likely to experience in its application.
• Output Signal: The output signal is the signal that the transmitter uses to communicate its pressure reading to a control system or other device. The Rosemount 3051S typically uses a 4-20 mA analog signal or a digital communication protocol such as HART or FOUNDATION Fieldbus.

Physical Specifications

• Materials of Construction: The materials of construction determine the transmitter's resistance to corrosion and other environmental factors. The Rosemount 3051S is available in a variety of materials, including stainless steel, Hastelloy, and Monel.
• Enclosure Rating: The enclosure rating specifies the level of protection that the transmitter provides against dust and water. The Rosemount 3051S typically has an IP66 or IP68 rating, meaning that it is dust-tight and can withstand immersion in water.
• Weight: The weight of the transmitter can be an important consideration in some applications, particularly where the transmitter needs to be mounted on a lightweight structure.
