The DPG1000L/DPG1100L series is a 2-wire pressure transmit-
ter with a digital display. It is powered by the 4-20 mA current
loop and produces an analog output signal. The output is filtered
to improve noise immunity. It may also be connected to a low
voltage DC supply for use as a pressure indicator.
Ranges up to 1999 have a 3.5 digit display and true analog
output. Ranges 2000 and above are microprocessor based
and use a 4 digit display with an alphanumeric lower display.
The output is a 12,000 count analog 4-20 mA signal updated
approx. 16 times per second.
Models are designed for continuous operation. Warm-up time is
negligible. The display will show the system pressure/vacuum
and the loop current will be proportional to the system pressure/
vacuum; 4 mA = Zero or low end, 20 mA = Span, full-scale or
high end.
The TEST button, when depressed, switches the display and
output loop to a preset level determined by the setting of a Test
potentiometer. This is useful for testing the 4-20 mA output
signal without having to alter system pressure.
