Ashcroft GC35 Digital Pressure Sensor

     Available in gauge pressure from 0-50 to 0-7500 psi and compound ranges up to 300 psi and vacuum, this versatile sensor includes a min./max. hold feature to record high and low pressure events, and adjustment for controlling display rates.  A rugged aluminum IP65/IP67 enclosure allows for a compact footprint and incorporates a highly visible LED display for local indication.  Analog scaling allows the user to configure the unit to any range within the full scale of the sensor range, while integrated switches offer the actuation and deadband to any points within the full scale range.    

• Combined Three-in-One Digital Pressure Gauge, Switch and Transducer 
•  High overpressure capability
• Unique high-visibility LED display and switch warning light functions
• GloBand™ display with 360 degree visibility
• All stainless steel wetted materials
• Simple "push-button" configurability allows user to adjust switch settings, analog scaling
• Numerous standard ranges available
• Rugged Aluminum housing

Hydraulic presses/stamping equipment/lifts, water/wastewater pressure control, pressure monitoring, water/refrigerant or ammonia based cooling systems, pressure monitoring on lubrication systems.
