                產(chǎn)品說(shuō)明:
                可選量程范圍,可選輸出信號(hào)
                WWDP系列 液用差壓變送器雖然只有三種型號(hào),但每種型號(hào)都有三十種可現(xiàn)場(chǎng)選擇的功能。WWDP系列能現(xiàn)場(chǎng)選擇單向量程或雙向正負(fù)量程,可選0-5, 1-5, 0-10VDC, 和4-20 mA的輸出信號(hào),還帶有自動(dòng)校準(zhǔn)零點(diǎn)的功能?,F(xiàn)場(chǎng)可選擇高低壓壓力接口的功能對(duì)于現(xiàn)場(chǎng)安裝方向錯(cuò)誤可無(wú)須重新安裝??蛇x的LCD顯示用于現(xiàn)場(chǎng)指示并同時(shí)輸出信號(hào)。鑄鋁外殼的防護(hù)等級(jí)為NEMA 4 (IP66)。這些功能使得WWDP差壓變送器廣泛地用于監(jiān)測(cè)氣體,液體流量,過(guò)濾器壓力降,有壓容器中的液位,等等能量管理系統(tǒng)中或過(guò)程控制系統(tǒng)中。
                產(chǎn)品規(guī)格:
                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 to 20 mA output cannot be powered with AC voltage.
                Output Signal: Selectable 0 to 5, 0 to 10 and 1 tp 5 VDC; 4 to 20 mA.
                Zero & Span: Digital "re" 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 Ω.
                Current Consumption: VDC power: 0 to 5, 1 to 5 VDC output 4 mA (typ); 0 to 10 VDC output 5 mA (typ); 4 to 20 mA output 20 mA max. Current consumption will equal the transmitter output in current mode. VAC power: 0 to 5, 1 to 5, 0 to 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.
