Barksdale D1H-H18SS Switch
The Barksdale D1H-H18SS is a heavy-duty diaphragm pressure switch designed for precision sensing in industrial and HVACR process control applications. Housed in a NEMA 4 aluminum enclosure, this housed pressure switch features a single setpoint mechanism with an adjustable range of 0.4 to 18 psi. The 316 stainless steel diaphragm and pressure connection ensure chemical compatibility and long-term durability when monitoring air, water, or oil systems. For contractors, the SPDT limit switch provides reliable electrical output, while the internal adjustment screw remains secure behind a gasketed cover to prevent tampering or environmental ingress. This industrial pressure control component is ideal for low-pressure monitoring where repeatability and deadband stability are critical for maintaining system safety parameters.
Key Benefits
- Environmental Protection: The NEMA 4 enclosure ensures reliable operation in washdown areas and harsh mechanical rooms.
- Corrosion Resistance: 316 stainless steel wetted parts prevent oxidation and material fatigue in high-moisture environments.
- Field Adjustability: The single setpoint can be precisely calibrated on-site using the internal adjustment screw to match specific application requirements.
- Superior Repeatability: High-quality diaphragm design provides consistent switching performance under varying ambient temperatures.
Common Questions
What is the maximum pressure limit for the Barksdale D1H-H18SS?
While the adjustable range is 0.4 to 18 psi, this switch is designed to withstand higher proof pressures; however, always verify system peaks against the manufacturer's maximum rating to prevent diaphragm deformity.
Can this pressure switch be mounted in any orientation?
For optimal accuracy and to prevent moisture accumulation, it is recommended to mount the unit with the pressure connection facing downward, though it is functional in multiple positions.
Is the D1H-H18SS suitable for hazardous locations?
The D1H series is a standard industrial housed switch; for explosion-proof requirements, installers should specify the Barksdale D1X or D2X series equivalents.
