Specifications - Installation and Operating Instructions
Series DM-1000 DigiMag
®
Digital Differential Pressure Gage
The Series DM-1000 DigiMag
®
Digital Differential Pressure Gage
is the ideal
digital instrument to take the place of analog mechanical pressure gages. The
DigiMag
®
Digital Gages are more versatile than analog gages with their ability to be
field-programmed to display many commonly used engineering units as well as
percent of full scale. The
Series DM-1000
can be programmed in 8 commonly
used engineering units plus percent of full scale. This capability allows quick units
selection on site, eliminating the need to calculate various unit conversions. The
DigiMag
®
Digital Differential Pressure Gages have an added feature for filter
applications where a set point can be input where the display will blink when the
filter is dirty, alerting the user that a maintenance action needs to occur.
Programming the Series DM-1000 is easy using the menu key to access 4
simplified menus which provide access to: Security level; engineering units; filter
set point; view peak and valley process readings; digital damping for smoothing
erratic process applications; display update to conserve battery life; zero and span
field calibration.
The Series DM-1000 DigiMag
®
Digital Differential Pressure Gage possesses a full
scale accuracy of 1% on ranges down to 2˝ w.c. and 2% accuracy down to the very
low ranges of 1” to 0.25" w.c. Models are also available with bi-directional ranges.
DigiMag
®
Digital Differential Pressure Gages offer power versatility by working with
9-24 VDC line power or simply 9V battery power. If using line power and
connecting the 9V battery, the battery will act as a back-up if line power is lost or
interrupted.
