DRUCK DPI 615 +/- 25 mBar Pressure Calibrator

Overview

The Druck DPI 610/615 LP series incorporates a precision low pressure sensor and pneumatic generator, to provide a fully self contained, portable low pressure calibrator. The key to the simple operation of the DPI 610/615 LP is the task menu. Specific operating modes such as P-I task sets the calibrator to source pressure and measure mA, and the P-Display task allows indicator readings to be manually entered and recorded, for example, when checking devices such as Magnehelic gauges. At low differential pressures, even connecting the device under test can induce significant pressure. To compensate for this, an “auto zero” facility is provided that uses an internal solenoid valve to equalize the differential pressure prior to zero correction.

This low pressure version of the Druck DPI 610 provides both manual and pump assisted generation of pneumatic pressure. For low volume systems or devices, test pressures are generated by a two stage (coarse/fine) volume adjuster. For larger volume external devices or systems, an external, hand operated, pneumatic pump may be used in conjunction with the Druck DPI 610LP to generate the required positive or negative test pressures. The calibrator’s output pressure is internally limited to 120% of the full scale pressure. If this pressure is exceeded for more than approximately 1 second, a valve within the calibrator opens, directly connecting the positive and negative pressure ports together, thereby relieving the excess pressure. When the pressure falls to within the operational limits, the valve automatically closes to allow normal operation to resume.
