Foxboro 13A-MS2-R 13A Pneumatic D/P Cell Transmitter

Configured for differential pressure measurement and signal transmission in pneumatic process loops, the Foxboro 13A-MS2-R (13A-MS2 Pneumatic D/P Cell Transmitter) provides direct physical execution across industrial monitoring networks. The unit processes process differential pressures across adjustable span limits and drives standardized 3-15 psi output signals to downstream receiving instruments. Built with a 316 stainless steel body, 1/2 NPT process connectors, and an integrated zero suppression kit, the assembly uses a mechanical force-balance mechanism to maintain continuous signal stability without electronic drift.

Process Control & Pneumatic Loop Execution

The transmitter operates as a purely mechanical force-balance instrument, converting process differential pressure acting on internal diaphragms into a proportional pneumatic output signal. Channel-to-channel isolation from electrical interference is inherently maintained, as the unit requires no internal electronic power supplies or current loops. Supply air conditioned to 20 psi passes through internal nozzle-flapper mechanisms to regulate the output between 3-15 psi. Cold junction compensation and electronic drift calibration are replaced by mechanical zero suppression adjustment via the suffix-R kit, permitting elevated line pressure offsets without signal saturation.

Frequently Asked Questions

Q: What air supply quality is required for reliable force-balance operation?

A: The transmitter requires a stable 20 psi (140 kPa) supply of clean, dry, oil-free instrument air. Contaminants or moisture in the supply line cause orifice clogging and nozzle-flapper degradation.

Q: How does the zero suppression kit (suffix R) alter baseline output calibration?

A: The zero suppression kit applies a mechanical spring tension to the force bar assembly, offsetting the initial 3 psi baseline to compensate for static head pressures on the low-pressure side.

Field Installation Guidelines

Process Thread Engagement: Apply thread sealant rated for process fluid compatibility and ensure a minimum of 5 full turns of NPT engagement on the 1/2 NPT process connectors.
Pneumatic Line Isolation: Install dedicated shutoff valves and air supply filter-regulators upstream of the 20 psi supply port to isolate instrument air during calibration.
Impulse Line Mounting: Mount impulse piping with a minimum slope of 1:12 toward the process taps to prevent gas accumulation in liquid lines or condensation buildup in gas lines.
Zero Adjustment: Verify line pressure equalization via a three-valve manifold before setting the mechanical zero screw under atmospheric reference conditions.
Environmental Sealing: Ensure front cover gaskets remain fully seated to uphold the NEMA 3 / IP53 enclosure rating against ambient dust and rain.
