Pneumatic Control Loop Execution and Isolation
Operating within pneumatic process measurement loops, the transmitter executes continuous force-balance differential pressure conversion without requiring electrical power sources, eliminating electromagnetic interference (EMI) susceptibility and electronic ground loop vulnerabilities. The rugged 316 stainless steel capsule and internal beam mechanism isolate the pneumatic signal paths from process fluid contact and ambient environmental shifts. Integrated regulating elements and zero suppression mechanics maintain measurement linearity and stability across high static pressure ranges, ensuring precise output transmission to downstream pneumatic controllers and indicators.
Frequently Asked Questions
Q: Does the 13A-MS2-R transmitter require electrical power for its signal transmission?
A: No. The 13A-MS2-R is a purely pneumatic device operating on a clean, dry instrument air supply (nominal 20 psi) and outputs a standard 3-15 psi pneumatic signal proportional to the measured differential pressure.
Q: What is the purpose of the -R optional suffix on this transmitter model?
A: The -R designation indicates that the unit is equipped with a zero suppression kit, allowing the transmitter to be calibrated for elevated zero conditions where a constant static head or pre-load pressure must be offset.
Field Installation Guidelines
- Ensure the instrument air supply and process isolation valves are shut and depressurized before handling or connecting lines to the transmitter body.
- Apply appropriate thread sealant conforming to plant standards to the 1/2 inch NPT process connectors, engaging a minimum of 5 full threads.
- Mount the D/P cell transmitter securely to a structural pipe stand or manifold bracket using robust mounting hardware to minimize measurement errors induced by heavy plant vibration.
- Verify that supply air pressure is maintained at the required nominal operating level using a clean, filtered, and oil-free instrument air source.
