United Electric H100-534 Pressure Switch
The United Electric H100-534 Pressure Switch is an industrial-grade electromechanical control engineered for precision monitoring in low-pressure air and gas systems. Featuring an adjustable setpoint range of 2.5 to 50 inches water column (wc), this 100 Series model is purpose-built for critical HVACR and process plant applications including airflow proving, filter status monitoring, and duct pressure control. The unit is equipped with a welded 316L stainless steel diaphragm for superior chemical resistance and durability when exposed to corrosive media. The NEMA 4X epoxy-coated aluminum enclosure provides a watertight, corrosion-resistant seal suitable for harsh environments or washdown areas. Utilizing a SPDT snap-action microswitch rated at 15A, the H100-534 offers reliable electrical switching. Its internal adjustment hex and reference scale allow for tamper-resistant setpoint calibration, ensuring system stability. With a robust 1/2 inch NPT female pressure connection and dual conduit entries, this switch ensures efficient field wiring and professional integration into complex control loops.
Key Benefits- Corrosion-Resistant Construction: Rugged NEMA 4X enclosure and 316L stainless steel wetted parts provide long-term reliability in demanding industrial climates.
- Broad Low-Pressure Range: Highly sensitive 2.5" to 50" wc adjustable range ideal for sensitive air handling and exhaust ventilation systems.
- Flexible Control Wiring: Single Pole Double Throw (SPDT) configuration allows for versatile normally open or normally closed circuit integration.
- Precision Repeatability: Engineered for ±1% setpoint repeatability, maintaining consistent performance across thousands of cycles.
- Simplified Installation: Features a slanted cover for easier terminal access and standard 1/2" NPTF process connections compatible with industry-standard fittings.
What is the maximum proof pressure for the H100-534?
This model is designed with a proof pressure rating of 100 PSI and an overrange pressure limit of 50 PSI. Exceeding these specifications can lead to sensor damage or setpoint drift.
Can this switch be used for liquid media?
While the stainless steel diaphragm offers excellent compatibility, the H100-534 is specifically optimized for air and gas applications. For liquid pressure monitoring, verify specific gravity and viscosity compatibility with the factory.
Is the setpoint adjustable in the field?
Yes, the setpoint is field-adjustable via an internal hex screw. The 100 Series includes a tamper-resistant lock to prevent unauthorized calibration changes after the initial setup.
