SERIES 3000MR AND 3000MRS PHOTOHELIC® SWITCH/GAGES Combines Differential Pressure Gage with Low/High Set-Points, Compact Size

the SERIES 3000MR AND 3000MRS Photohelic®
Switch/Gages combine the functions of a precise, highly repeatable differential
pressure switch with a large easy-to-read analog pressure gage employing the
durable, time-proven Magnehelic® gage design. Switch setting is easy to adjust with
large external knobs on the gage face. Gage reading is unaffected by switch operation
- will indicate accurately even if power is interrupted. Solid state design now results
in greatly reduced size and weight. Units can be flush mounted or surface mounted
with hardware supplied. 3000MR models employ versatile electromechanical relays
with gold over silver contacts - ideal for dry circuits. For applications requiring high
cycle rates, choose 3000MRS models with SPST (N.O.) solid state relays. All models
provide both low and high limit control and include 18-inch (45 cm) cable assemblies
for electrical connections.
Compatible with air and other non-combustible, non-corrosive gases, they can be used
in systems with pressures to 25 psig (1.725 bar). Optional construction is available for
use to either 35 psig (2.42 bar) or 80 psig (5.51 bar).
FEATURES/BENEFITS
• Gage reading unaffected by switch operation and will continue to read pressure even
during power loss
• Zero and range adjustments outside of gage means no disassembly in normal
service
• Solid-state design allows for switching in high cycle rate applications without
degradation
APPLICATIONS
• Pneumatic conveying
• Air conditioning systems
• Clean rooms
