Ashcroft N [NPA] Pressure Switches

The Ashcroft N Series electronic pressure switches are in even the toughest industrial applications. The pressure sensor is a standard Ashcroft K Series thin film transducer. The signal developed in the transducer is processed on a conformal coated printed circuit board to produce an output to a high quality electromechanical relay, which is rated for 10,000,000 cycles at rated load. The result is a long lasting pressure switch that will outlast mechanical switches in high cycle applications such as metal stamping presses, plastic injection molding machines, and other machine tools and special equipment. The N Series also features narrow, adjustable deadbands that can be adjusted to less than 0.5% of range, solving many pipeline and elevated tank applications that are out of the reach of mechanical products.

The indicating model is ideally suited for applications where both a pressure indicator and a switch output for alarm, shutdown, control, or interlock are needed. Sludge and slurry applications in wastewater and pulp and paper mills often require costly diaphragm seals to isolate instruments from the clogging effects of the process. You can save money by installing the N Series switch with indication on a single seal. You can even set the switch set and reset points on a test bench without pressure on the system, using the indicator and status lights.

Ideal for pressure alarm, shutdown & control on:

• Machine tools
• Injection molding machines
• Presses
• Pumps
• Hydraulic systems
• Turbines and compressors
• Pipelines
• Most process applications
• All high-cycle applications
