Dwyer Instruments CXA-S1 Pressure Switch
The Dwyer Instruments CXA-S1 is a robust water pump pressure switch designed for automated control in potable water systems and light industrial applications. Featuring a normally closed (NC) contact configuration, this unit operates within a 15-80 psig pressure range, providing reliable startup and shutdown cycles for booster pumps and well systems. The adjustable deadband of 15-30 psig allows technicians to fine-tune the differential, preventing short-cycling and protecting the motor from premature wear. Built with a 1/4" female NPT process connection, the CXA-S1 ensures a secure, leak-free integration into standard plumbing manifolds. Its simple, field-proven mechanical design handles high-current loads without the need for additional relays in many standard 120V/240V configurations. When field-calibrating, utilize the internal adjustment screws to match the system’s specific cut-in and cut-out pressure requirements. This industrial pressure controller is the professional choice for maintaining consistent line pressure in demanding water distribution setups.
Key Benefits for Contractors
- Field Adjustability: The 15-30 psig adjustable differential allows for precise control over pump cycles to optimize system efficiency.
- Heavy-Duty Contacts: Designed to handle the high inrush current of well pump motors, ensuring long-term switching reliability.
- Standardized Fitting: The 1/4" NPT connection facilitates direct replacement of most OEM switches without extensive repiping.
- Durable Housing: Rugged construction protects internal components from debris and environmental stress in mechanical rooms.
Common Questions
How do I adjust the cut-in and cut-out points on the CXA-S1?
Adjustments are made via the internal springs. The primary nut sets both points simultaneously, while the smaller differential nut narrows or widens the gap between the trip pressure and reset pressure.
Can this switch be used with air compressors?
While functionally similar to an air pressure switch, the CXA-S1 is specifically optimized and rated for water system parameters. Always verify medium compatibility and max pressure ratings before installation.
What is the purpose of the normally closed contact?
In a pressure-activated switch, normally closed means the circuit is complete (pump running) until the rising pressure reaches the set point, at which time the contacts open to stop the motor.
