Setra SRPMR05WBA1E Pressure Monitor

The Setra SRPMR05WBA1E is a high-precision room pressure monitor engineered for critical low-differential pressure applications in healthcare and laboratory environments. Built with an on-board, dead-ended capacitive sensor, this unit maintains tight atmospheric control without the cross-contamination risks associated with flow-through designs. The SRPM-R05WB-A1-E features a 2-inch backlit touchscreen LCD display, offering a streamlined interface for real-time monitoring of pressure relationships in isolation rooms, cleanrooms, and sterile processing areas. Supporting a standard 24 VAC excitation, it provides selectable analog outputs including 4-20 mA, 0-5 VDC, and 0-10 VDC, ensuring seamless integration with diverse building automation systems (BAS).

Designed for field reliability, this differential pressure sensor offers ±0.5% FS accuracy and a robust NEMA 1 fire-retardant housing. The surface-mount configuration simplifies installation in existing facilities, while the integrated audible and visual alarms provide immediate notification of pressure breaches. With two-level password protection and a digital input specifically for door status monitoring, the Setra SRPM ensures secondary security protocols are met. Technicians benefit from the built-in calibration feature, which only requires zeroing upon installation to maintain high-performance sensing of positive or negative room pressures.

• Enhanced Accuracy: Delivers ±0.5% Full Scale accuracy for precise tracking of low differential pressure fluctuations.
• Versatile Output Signals: Field-selectable 4-20 mA, 0-5 VDC, and 0-10 VDC outputs for universal HVAC monitoring compatibility.
• Contamination Control: The dead-ended pressure sensor design prevents air from passing through the unit, safeguarding cleanroom integrity.
• Simplified Setup: Intuitive touchscreen interface allows for rapid configuration of alarm setpoints and delay parameters without specialized tools.
• Integrated Safety: Features a local audible horn and RGB backlit visual alerts (red/green) for at-a-glance status verification.

Can this monitor be used for both positive and negative pressure rooms?
Yes, the bi-directional sensor allows the unit to be configured for either protection (positive) or isolation (negative) modes depending on the application requirements.

Does the unit support door status monitoring?
The SRPM includes a dedicated digital input for a door switch, allowing the system to monitor door status and delay alarms to prevent nuisance alerts during normal entry and exit.

What is the benefit of the dead-ended sensor over flow-through models?
Dead-ended sensors eliminate the physical air path between the monitored room and the reference space, preventing the transfer of pathogens or contaminants and avoiding sensor fouling from airborne particulates.
