DSA3218-PTP/16Px - Absolute

The DSA3218-PTP/16Px module can be used for absolute
pressure measurement when equipped with absolute pres-
sure transducers. A calibration valve is provided for each
group of eight (8) sensors. All sixteen (16) transducers are
tied a single calibration port, except in the cases of dual-
range absolute modules. Figure 2.11 depicts the top panel
of a DSA3218-PTP/16Px absolute pressure module.

DSA3218-PTP Heater Option

The DSA3218-PTP series module can be equipped with
an internal heater for cold environment applications. The
heater kit option increases the DSA3218-PTP's operational
ambient temperature range to -55°C to 60°C by maintaining
the internal temperature of the module at approximately
+20°C. With a heater installed, the power requirements
for the DSA3218-PTP module increase to: 20-36Vdc @ 40W
(28Vdc nominal). The power consumption of the module
will decrease once the temperature of the module has
stabilized.

DSA3218-PTP Cooling Kit Option

For applications where the DSA3218-PTP module must
operate in ambient temperatures above the specified oper-
ating range, a cooling kit option is available. The cooling
kit provides two (2) 3/8" Swagelok® fittings on the outside
of the case and internal baffling to allow cool Nitrogen (or
clean, dry air) to be circulated through the unit. The exact
cooling flow requirements and the maximum operating
temperature are different for each application, but for most
applications the DSA3218-PTP can be operated up to 80°C
ambient temperature if sufficient cooling flow is provided.
For most cases, 2-3 SCFM of 25°C should be supplied into
the module.
