National Controls Corporation-Pressure Differential Meter (Model: DNC-PS700-A10)

The DUSTRONIX Pressure Differential Meter is designed to interface with NCC dust collector controls as well as other controllers. This meter is capable of measuring differential pressure and displaying that value in both analog bargraph and digital displays. Both Low/High Cleaning and Low/High Alarm setpoints can be programmed with relay outputs. The Cleaning relay will energize when the measured pressure exceeds the High Cleaning Setpoint, and will de-energize when the pressure goes below the Low Cleaning Setpoint. The Alarm relay will energize whenever the measured pressure exceeds the High or Low Alarm Setpoint.

The DUSTRONIX Pressure Differential Meter will accept either a 0 to 10” w.c. pressure input or a 4 to 20 mA input. A 4 to 20 mA output loop is provided when the internal pressure sensor is used. A 3-digit security code is also provided to prevent unauthorized changes. The meter is equipped with non-volatile memory which will store all operating parameters when power is removed.

Operating Logic: The DUSTRONIX Pressure Differential Meter is shipped with factory default settings (see details below). A pressure or 4 to 20 mA input needs to be connected, outputs wired as required, and power applied to have a functioning system.  Program parameters can now be set for the specific application.
