Product Features

Visible Set Point Indicator - A clear, easy-to-read dial allows real-time visualization of the pressure set point, simplifying initial setup, operation, and troubleshooting. This feature reduces downtime by enabling quick identification of activation thresholds without additional tools.
Large Diaphragm for Low-Range Accuracy - The switches utilize a large diaphragm design to deliver precise pressure sensing in low ranges, ensuring reliable activation at exact pressure points. This makes them suitable for applications where minor pressure fluctuations require responsive control, such as fan coil systems, air handlers, or fluid level monitoring.
High Current Load Capability - With the ability to support current loads up to 15 amps, the 1638 Series eliminates the need for additional relays or components in most small electrical systems. This simplifies wiring in HVAC installations, pump control, and process equipment, reducing installation costs and complexity.
Versatile Model Selection - Available models cover a range of pressure spans to match diverse application needs:
- 1638-0: Ultra-low range for delicate pressure sensing
- 1638-1/2/5/10: Graduated ranges for medium to higher low-pressure applications
Rugged Construction - Built to withstand industrial environments, the switches offer durable performance in HVAC ducts, process lines, and mechanical systems.
