DM-2012-LCD DM-2107-LCD 差压变送器 Dwyer原装

The Dwyer SERIES DM-2000 Differential Pressure Transmitter senses the pressure of
air and compatible gases and sends a standard 4-20 mA output **. The DM-2000
housing is specifically designed to mount in the same diameter cutout as a standard
Magnehelic? gage. A wide range of models are available factory calibrated to specific
ranges.
Pressure connections are inherent to the glass filled plastic molded housing making
installation quick and easy. Digital push-button zero and span simplify calibration over
typical turn-potentiometers. An optional 3.5 digit LCD shows process and engineering
units. A single push button allows field selection of 4 to 6 engineering units depending
on range.
FEATURES/BENEFITS
? Zero and span controls provides easy calibration checks and shorter installation
time to get device running and monitoring
? Quick response to pressure changes means no delay in **ing and alerting to
critical situations
? Easy to read LCD display provides immediate local alerts allowing corrective action
to be taken quicker to eliminate the problem from becoming widespread
? Same size as Magnehelic simplifies field upgrade to digital pressure gage by
reducing install steps
APPLICATIONS
? Differential pressure across filters
? Fan control
? Static pressures in ducts or buildings
