接液材質(zhì): 316L SS.

外殼: Glass filled plastic.

精度: ±1% of F.S. including linearity, hysteresis, and repeatability (indicator and transmitter).

穩(wěn)定性: < ±2% of F.S. per year.

壓力限制: Ranges up to 6,000 psi: 1.5 x range; 8,000 psi range: 10,000 psi.

溫度限制: Ambient: 20 to 140°F (-6.6 to 60°C); Process: 0 to 176°F (-18 to 80°C).

補(bǔ)償溫度限制: 32 to 122°F (0 to 50°C).

熱效應(yīng): ±0.05% of F.S./°F.

顯示: 4-digit backlit LCD (Digits: 0.60"H x 0.33"W).

電源: 12 to 30 VDC/AC.

能耗: 2.5 watts.

電氣連接: Removable terminal blocks with two 1/2" female NPT conduit connections.

封裝等級(jí): Meets NEMA 4X (IP65).

預(yù)熱時(shí)間: <10 seconds.

安裝方向: Any position.

認(rèn)證: CE and UL.

開關(guān)特性:

開關(guān)類型: 2 SPDT relays.

電氣額定: 5 A @ 120/240VAC, 1 A @ 30 VDC.

重復(fù)性: ±1% of FS (switching only).

設(shè)定點(diǎn): Adjustable 0-99% of FS.

開關(guān)指示: External LED for each relay on the front panel.

開關(guān)復(fù)位: Manual or Automatic.

變送器特性:

輸出: 4-20 mA, 1-6 VDC, 1-5 VDC, 0-5 VDC, or 0-10 VDC (direct or reverse output selection).

最小激勵(lì)電壓: 14 VDC.

零滿調(diào)整: Menu scalable within the range

顯示單位: psi, kg/cm², bar, in Hg, ft w.c., kPa, MPa, %FS, in w.c., mbar, cm w.c., mm Hg, or oz/in² (choices depend on range).

測試方式: Simulates input over the range without pressuring to easily test switches and transmitter output feature.

故障保護(hù): For sensor failure, over pressure, high temperature limit, low temperature limit, or keypad short. User chooses if relay is de-energized, energized, or no action. With transmitter option, user chooses an output of 3.6 mA 22 mA, or no action.

交替: Selectable alternation of set points between the relays for even wear on duplex pump applications.
