Cleveland Controls NS2-0438-00 Pressure Switch
The Cleveland Controls NS2-0438-00 Pressure Switch is a high-performance air pressure sensing switch designed for residential and light commercial HVAC applications. Engineered with a glass-filled polycarbonate body and a silicone diaphragm, this unit is built to withstand operating temperatures from -40°F to 190°F. This specific model features a factory-calibrated set point of .80" w.c., making it a critical component for monitoring positive, negative, or differential air pressure in systems requiring precise set point tolerance. The SPDT contact arrangement and 1/4" quick-connect terminals ensure seamless integration into existing control circuits, while the narrow switching differential provides the reliability seasoned contractors expect when troubleshooting airflow proving or blocked vent detection issues.
Key Benefits
- Comes factory-calibrated at a .80" w.c. set point for accurate differential pressure sensing.
- Robust construction using glass-filled polycarbonate ensures metabolic stability in demanding environments.
- Versatile SPDT electrical load capability supports various furnace and air handler control configurations.
- High-quality silicone diaphragm maintains sensitivity and performance over a minimum of 250,000 cycles.
- Color-coded sample line connectors (Black for positive, Gray for negative) simplify field installation.
Common Questions
Can I use this switch for both vacuum and pressure applications?Yes, the Cleveland Controls NS2-0438-00 can be configured to sense positive, negative, or differential pressure by utilizing the color-coded P1 (positive) and P2 (negative) ports accordingly.
Is this a suitable replacement for other NS2 series switches?While the NS2 series is broad, you must match the .80" w.c. set point and terminal configuration. Using a switch with a different set point can result in unsafe operation or system lockout.
What type of tubing is compatible with the ports?The integral slip-on connectors are designed to accept 3/16" ID flexible tubing, which is the standard for most HVAC pressure switch diagnostics and installations.
