Ashcroft GC31 Ultra-Compact Digital Pressure Sensor Switch
The new Ashcroft Model GC31 is a uniquely compact pressure sensor, ideal for monitoring pressures in hydraulic presses/stamping equipment and lifts, tire vulcanization, cooling and lubricating systems, alarm/control and pressure monitoring where consistent, reliable, pressure measurement is essential. The GC31 is equipped with Ashcroft's field-proven thin film sensor and can monitor a wide variety of applications.
Available in gauge pressure from 0-50 to 0-1500 psi and compound ranges up to 150 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. The 1.2" x 1.2" (30 mm x 30 mm) enclosure incorporates a 3 1/2 LED display. 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.
Applications
- Hydraulic presses, stamping equipment, lifts
- Tire press vulcanization, pressure monitoring
- Water, refrigerant or ammonia based cooling systems
- Pressure monitoring on lubrication systems
Features
- Ultra-compact design 1.2˝ x 1.2˝ (30mm x 30mm)
- Combined three-in-one digital pressure gauge, switch and transducer
- Simple “Push-Button” configurability allows user to adjust switch settings, analog scaling
- Numerous standard ranges available
