The Ashcroft GC30 digital differential pressure sensor is a uniquely compact pressure sensor, ideal for monitoring differential pressures in clean rooms, filters, and fan speed or vacuum/suction pressure sensing and control where consistent, reliable pressure measurement is essential. The Ashcroft GC30 is equipped with Ashcroft's highly reliable SiGlas sensor and can monitor a wide variety of applications.

Ashcroft GC30 ultra-compact digital differential pressure sensors are available in differential gauge pressure from 0.25 to 25in water column and differential compound pressures from ±0.25 to ±25in water column. These versatile sensors include a MIN/MAX HOLD feature to record high and low pressure events, and adjustments for controlling display rates.

The 1.2 x 1.2 inch (30 x 30mm) enclosure incorporates a 3½ digit 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 for control or safety offer the actuation and deadband to any points within the full scale range.
