PRODUCT SPECIFICATIONS
TYPE & RANGE:
DN: Differential Non-isolated
DI Differential Isolated
GI: Gauge Isolated
CI Compound Isolated
AI Absolute Isolated
MEDIA COMPATIBILITY: Non-isolated sensor
for clean, dry, non-corrosive gases. Isolated sensor for
fluids compatible with 316SS.
ACCURACY*: ± 0.05% of Full Scale for Pressure
reading in InH
2
O @ 20
°C (includes combined effects of
linearity, repeatability, hysteresis and temperature).
AC-powered gauges require 15 minute warm-up.
NIST certification supplied.
ZERO DRIFT: ± 0.015% of Full Scale. Zeroing
prior to measurement eliminates this effect.
TEMPERATURE:
Storage: -40 °F to 140 °F (-40 °C to 60 °C)
Operating: -4 °F to 122 °F ( -20 °C to 50 °C)
PRESSURE LIMITS: 2x range for AI, GI, and CI
sensors. 2x range for DN sensors when pressurized on
high side only; 150 PSI static when applied to both
sides of the sensor simultaneously. 3x range for DI
sensors when pressurized on high side only, 1000 PSI
static when applied to both sides of the sensor
simultaneously. 3x range or 150 PSI on low side
whichever is less.
DISPLAY: 4 1/2 digit, 0.6 inch (15.24 mm) LCD.
PRESSURE CONNECTIONS: 1/8" female NPT.
Brass on non-isolated, 316SS on isolated sensors.
INPUT POWER: SetPoint model is standard with
selectable 110V AC 50/60 Hz, 220V AC 50/60 Hz, or
24V DC power. Included are an RS 232C interface
and two programmable SPDT relays, rated 1.0 amp
resistive @ 24V DC, 0.5 amp resistive @ 115V AC.
Battery models are powered by two Lithium “D”
Cells. Battery Life is approximately 100 days at a
100% duty cycle.
I/O: Included are an RS 232C interface and two
programmable SPDT relays, rated 1.0 amp resistive @
24V DC, 0.5 amp resistive @ 115V AC.
Option 1: Lithium Battery model with
replaceable battery board with automatic shut-off
(programmable). No outputs available.
Option 2: Current Loop model with 4-20mA output,
24V DC (50mA) power and RS 232C.
ENCLOSURE: 4 lbs. 1/4 DIN (3.8" X 3.8" X 6.5")
aluminum enclosure with epoxy finish. Standard
model is NEMA 4X on front panel only. Battery and
Current Loop models are NEMA 4X throughout.
MOUNTING: 1/4 DIN panel mounting standard.
Options: 2" pipe mount bracket; or portable handle.
