Measure and Control building/room pressure, air flow, duct pressure or filter
drop with the Series 674 Differential Pressure Transmitter. These versatile transmitters provide
up to six field selectable direct or compound pressure
ranges. Additional features include 10 psid overpressure
without zero shift, non-interactive zero and span adjustment,
temperature compensation, short circuit and reverse polarity
protection. |
- Service: Clean dry air or any inert gas.
- Accuracy: ± 1% FS (includes non-linearity,
hysteresis and non-repeatability).
- Overpressure: 10 psid (0.7 kg/cm²).
- Output: 4-20mA, 2-wire.
- Supply Voltage: 12-40 VDC.
- Loop Resistance: 1600 Ohms @ 40VDC.
- Zero and Span Adjustment: ±15%, non-interactive.
- Stability: Less than 1% FS/year.
- Operating Temperature Range: 0 to 175°F
(-18 to 80°C), 10 to 90% RH, non-condensing.
- Compensated Temperature Range: 25 to 150°F
(-4 to 65°C).
- Thermal Errors: ±0/0125%/F (0.02%/C).
- Response Time: 60 msec.
- Pressure Connections: Barbed for 1/4"
O.D. 5/32" I.D. tubing.
- Wetted Parts: Brass hose barbs, silicone.
- Enclosure: Models 674-4XX: Cold-Rolled Steel,
NEMA-4 (IP56); Models 674-1XX: Panel Mount.
