GENERAL INFORMATION
The GP Series pressure sensor is a 4-20mA current
output device that is designed to provide excellent
accuracy and reliability in commercial, industrial, and
process control applications where performance is
critical. The GP Series is available in two pressure
sensing types: Gage (PSIG) and Sealed Gage (PSIS).
Gage sensors (PSIG) measure pressure relative to
ambient pressure through a port that is open to the
atmosphere, and are used in lower pressure
applications where measurement in a vacuum is not
required. Sealed sensors (PSIS) measure pressure
relative to a port that is connected to a sealed perfect
vacuum chamber. Sealed pressure transducers are
calibrated to have 4 mA at +14.5 PSIA.
OPTIONAL ACCESSORIES
Pressure Snubber
ACI recommends the use of the A/0.25” Snubber
(Water or Air/Gas) with all GP series sensors. The use
of a pressure snubber is a cost-effective solution that
can extend the life of your sensor by smoothing out
pressure spikes, surges and pulsations, and prevent
debris from collecting in the sensor diaphragm
opening. The A/0.25” Snubbers are made of 316 Stainless Steel and should be used with compatible
materials.
Syphons
The A/Syphon must be used to protect the sensor from extreme operating temperatures when the
operating temperature of the steam being monitored is higher than the maximum operating temperature
of the GP pressure sensor. There are three bend configurations available (90˚, 180˚, and 270˚) to allow the
mounting of the sensor vertically away from the main pipe.
NEMA 4 Enclosure
ACI recommends the use of a NEMA 4 enclosure to protect the gage pressure sensor in applications where
debris and moisture could contact the sensor or electrical connections. The A/GP-(xx)-NEMA 4 GP Series
pressure sensor is mounted in a NEMA 4 Rated, steel enclosure with one ½” conduit knockout. A ¼” male
NPT Stainless Steel fitting is provided for installation to your pipe, tank, or reservoir.
