Electronic Pressure Switches, Watertight or Explosion-Proof Enclosure
N-Series
• Ashcroft® K Series polysilicon thin film pressure sensor (transducer) for long, stable life (minimum 1 million cycles at rated load)
• Setpoint repeatability of 0.5% of range
• Choice of watertight, NEMA 4 or explosion-proof NEMA 7/9, IP66 enclosures for safety and reliability
• Pressure setpoints to 20,000 psi
• Deadbands adjustable between 0.1% and 95% of nominal range
• Multi-turn potentiometers make setpoint and deadband adjustments easy
• Status lights indicate switch state
• Continuous power assures operation first time and every time even after years of inactivity
Ideal for pressure alarm, shutdown, control on:
• Machine tools
• Injection molding machines
• Presses
• Pumps
• Hydraulic systems
• Turbines and compressors
• Most process applications
