The new Ashcroft Model GC30 is a uniquely compact pressure sensor, ideal for monitoring differential pressures in clean rooms, filters, fan speed control and vacuum/suction pressure sensing & control where consistent, reliable pressure measurement is essential. The GC30 is equipped with Ashcroft's highly reliable SiGlas™ Sensor and can monitor a wide variety of applications.
Available in differential gauge pressure from 0.25" to 25" water column and differential compound pressures from ±0.25" to ±25 water column, this versatile sensor includes a min./max. hold feature to record high and low pressure events, and adjustment for controlling the display rates. The 1.2" x 1.2" (30 mm x 30 mm) enclosure incorporates a 3 1/2 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.
