OMEGA’s melt pressure indicators
also function as transducer power
supplies and signal conditioners.
The DP434 Digital Model has a
large 88.9 mm (31⁄2") digit LED
display which is easy to read, even
from a distance, while the DP409
Analog Model has a 152.4 mm (6"),
240° arc (international scale) for
easy viewing. Both units are housed
in a standard 1⁄4 DIN case.
The DP434 and DP409 are
designed for use with OMEGA’s
melt pressure transducers or any
4-leg, 350 Ω Wheatstone bridge
strain gage transducer. A calibration
switch allows for a quick span check
and adjustment for zero at zero
pressure. The complete electronics
assembly can be removed and
replaced from the front without
disturbing the wiring in back.
Dual setpoint models can be used
to give a preliminary warning before
an actual shutdown sequence is
initiated. HI/HI LO/LO, LO/Hl, or
HI/LO alarm modes can be
programmed, and the relays are
isolated during a setpoint change or
calibration check to prevent
accidental emergency shutdown.
Cables and Sensor Sold Separately.
