Dwyer Photohelic Switch 3000MRS-00 3000MRS-0 3001MRS 3002MRS Differential Pressure Gauge
Product Introduction
The Dwyer Photohelic Switch Series combines pressure gage functionality with solid-state switching capabilities, designed for reliable performance in industrial applications. Engineered to maintain gage readings unaffected by switch operations—even during power loss—these switches feature external zero and range adjustments, eliminating the need for disassembly during normal service. The solid-state design enables high-cycle switching, while optional configurations (tamper-proof, weatherproof, high-pressure) enhance versatility for diverse environments.
Product Features
Independent Gage & Switch Operation:
Gage readings remain accurate regardless of switch activation, ensuring continuous pressure monitoring.
Maintains pressure display during power outages for critical system visibility.
User-Friendly Calibration:
Zero and range adjustments accessible outside the gage housing, simplifying on-site maintenance without disassembly.
Solid-State Durability:
High-cycle switching capability suitable for frequent operation in automated control systems.
Reduces wear compared to mechanical switches, enhancing long-term reliability.
Configurable Options:
-TAMP: Tamper-proof knobs with spanner key for secure set point adjustments.
-LT: Low-temperature compatibility for use below 20°F (-6.7°C).
-MP/-HP: Medium (35 psig) or high (80 psig) pressure ratings for robust system integration.
-WP: Weatherproof housing for outdoor or harsh environment installations.
Versatile Application:
Ideal for HVAC, filter monitoring, and industrial processes requiring both pressure indication and automated switching.
Reliable Performance:
Mechanical design ensures consistent pressure measurement alongside solid-state switching precision.
