Dwyer Instruments CS-1 Pressure Switch
The Dwyer Instruments CS-1 Pressure Switch is a technical-grade diaphragm pressure switch engineered for precision vacuum pressure monitoring in commercial and industrial HVACR environments. Built for reliability, this unit handles an adjustable vacuum range from 1" to 30" Hg (25.4 to 762 mm Hg), providing versatile control for vacuum pump systems and process automation. The fixed deadband is set at 1.5" Hg (38 mm Hg), which prevents rapid cycling and ensures stable operation under fluctuating conditions. For electrical integration, it features a SPDT snap switch with high-capacity terminals, allowing for normally open or normally closed wiring configurations. Professionals prefer the CS-1 for its robust 30 Psig pressure limit and standard 1/4" NPT process connection, making it a direct-fit solution for most manifold and piping layouts.
Technical Benefits for Contractors:
- Wide Vacuum Range: Covers 1-30" Hg, allowing for precise adjustment across various negative pressure applications.
- High Stability: The fixed 1.5" Hg deadband value maintains consistent switching points without constant recalibration.
- Industrial Build: Durable diaphragm construction rated for a maximum internal pressure of 30 Psig to prevent rupture during system surges.
- Easy Integration: Features a standard 1/4" male NPT connection and SPDT contacts for seamless HVAC mechanical switch replacement.
- Compact Form Factor: Designed for tight mechanical rooms and equipment cabinets where space for pressure control devices is limited.
Common Questions & Technical Support:
Can the CS-1 be used for positive pressure sensing?
No, the CS-1 is specifically calibrated as a vacuum switch for negative pressure. For positive pressure applications, refer to the Dwyer Series 1000 or equivalent diaphragm switches.
What is the maximum electrical load for the SPDT switch?
The Dwyer CS-1 typically handles standard pilot duty and motor loads; however, always verify the specific amperage on the nameplate to ensure compatibility with your industrial vacuum control circuit.
How do I adjust the set point on this unit?
The set point is adjusted via the internal nut. Clockwise rotation typically increases the vacuum setting. Use a calibrated vacuum gauge for final commissioning to ensure accurate vacuum pressure activation.
