Frequently Asked Questions (FAQ)
Q: What is the primary application of the Rosemount 1151 Pressure Transmitter?
A: Its primary application is for measuring differential pressure, which is commonly used to infer flow rate (using an orifice plate), liquid level in closed tanks, or filter/pipe blockage status in various industrial processes.Q: Does the 1151 transmitter require a separate power supply?
A: No, it is a two-wire, loop-powered device. It operates on a 4-20 mA signal line, drawing its power (10.5-45 V DC) from the same two wires used for the output signal, simplifying wiring.Q: Can I communicate with the transmitter digitally?
A: Yes, models with the HART option support digital communication. Using a HART communicator or compatible software, you can remotely read variables, reconfigure parameters, and perform diagnostics without interrupting the analog signal.Q: What materials are compatible with the sensing diaphragm?
A: The standard diaphragm is 316L stainless steel, which is compatible with a wide range of process media including water, oil, gases, and many mild chemicals. For more aggressive media, alternative diaphragm materials may be available upon request.Q: How do I select the correct measurement range?
A: The range should be selected based on your normal operating pressure and the required turndown. It's recommended to choose a range where the normal operating point is between 50% and interaction: 75% of the span for optimal accuracy. Our team can assist you in selection.Q: Is the Rosemount 1151 suitable for outdoor installation?
A: Yes, its robust housing with epoxy coating provides protection against environmental factors. However, for extreme conditions, optional protective enclosures or sunshades might be considered.Q: What is the typical calibration interval for this transmitter?
A: Due to its stable performance, the typical recommended calibration interval is 12 to 24 months, depending on the application severity. The HART functionality allows for easy verification of performance trends.Q: Can Rossonix provide technical support and documentation?
A: Absolutely. As an established trading company with extensive experience, we provide datasheets, manuals, and basic application support for the products we supply to ensure proper integration into your systems.
