Differential Pressure Transmitter Dwyer
Specification
Service: Gases or liquids compatible
with 17-4 PH stainless steel.
Accuracy: All pressure ranges have
± 1% full scale accuracy except the
lowest selectable range of each unit is
± 2% full scale.
Stability: ± 0.5% per year.
Temperature Limits: Compensated
temperature range: 32 to 130° F
( 0 to 54° C) ; Operating temperature
range: -4 to 185° F ( -20 to 85° C) .
Pressure Limits: Max working
pressure: WWDP-1: 50 psi; WWDP-2:
100 psi; WWDP-3: 250 psi; Proof
pressure: 2.2X of full scale; Burst
pressure: 40X of full scale.
Thermal Effect: 2% FS/ 100° F ( 50° C)
includes zero and span.
Power Requirements: 12 to 30
VDC/ 18 to 28 VAC ( reverse excitation
protected) . Note: 4-20 mA output
cannot be powered with AC voltage.
Output Signal: Selectable 0-5, 0-10
and 1-5 VDC; 4 to 20 mA.
Zero & Span: Digital â reâ zero button
( should be used when changing
ranges) . Span can be adjusted by
changing between field selectable
ranges.
Response Time: 1 to 5 sec
( selectable) .
Loop Resistance: 1000 ohms.
Current Consumption: VDC power: 0-
5, 1-5 VDC output 4 mA ( typ) ;
0-10 VDC output 5 mA ( typ) ; 4-20 mA
output 20 mA max. Current
consumption will equal the transmitter
output in current mode. VAC power: 0-
5, 1-5, 0-10 VDC output 40 mA ( typ) .
Electrical Connections: 1/ 2Ã conduit.
Process Connections: 1/ 8Ã female
NPT internal.
Enclosure Rating: Designed to meet
NEMA 4 ( IP66) .
Mounting Orientation: Vertical; mount
the pressure ports down ( keeps debris
from building up inside the pressure
port) .
Weight: 1.5 lb ( 680.4 g) .
Agency Approvals: CE.
