Công Tắc Áp Suất Series WWDP
| Model |
: |
SERIES WWDP |
| Manufacturer |
: |
DWYER |
| Origin |
: |
USA |
| 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 "re" zero button (should be used when changing ranges). Span can be adjusted bye 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 |
: |
1/2" conduit. |
| Process Connections |
: |
1/8" 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. |
