Honeywell 熱解探測器

特點: 可擕式熱解探測器設計用於探測含氯和含氟氣體。可擕式熱裂解探測器是由三個基本元件構成的，即：帶有集成泵的取樣模組，可用於採樣，以及將氣體轉化為無機酸的熱裂解器和用於探測這些氣體的氣體探測模組。該儀器的自我診斷功能包括對預設溫度和流率的監測。 對於緊急回應以及在實驗室、氣瓶接收區域和其他需要監測流動或臨時檢測氣體的地方而言，可擕式熱解探測器是最理想的解決方案。 可擕式熱解器的特點是帶有用戶可調的雙級別濃度報警、LCD濃度顯示幕以及視聽報警指示器。該儀器還將三個報警繼電器合併在一起，一旦探測到氣體濃度或儀器報警條件，這三個報警繼電器便自動啟動外部裝置。除了報警繼電器外，購買時該儀器可選配LonWorks®或4 - 20 mA介面。 該儀器更多的特點和優點：持續的監測、快速的回應、音頻報警可以進行靜音設置的能力、電池檢查和MST Technology智慧電化學感測器元件的使用。每台熱解器儀器都被校準以便回應某種可用氣體類型。 可偵測氣體種類: Di-chloro-ethylene 1.2 (DCE 1.2) Hexaflouro-1.3-butadiene (C4F6) Methyl Flouride (CH3F) Nitrogen Trifluoride (NF3) Octafluorocyclopentene (C5F8) Sulfur Hexafluoride (SF6) Performance specifications Alarm settings: Dual-level Battery life (Pyrolyzer): 1 h 30 min when fully charged Operation temperature: -20 °C to +40 °C(-4 °F to +104 °F) Relative humidity: 20 to 90 % r.h.(non-condensing) Pressure: 700 hPa to 1300 hPa Sampling tubing: OD 1/4 in ID 3/16 in Response time: < 30 sec(10 m tubing length)Operational cell life > 1 year(under normal conditions) Sensor service interval: 6 months Applicable standards: RFI / EMC: EN 55022 & EN 50082-2 Graphic display: 122 x 32 dots with back light LED indication: Alarm, fault, power status Acoustical alarm: Continuous / alternating / buzzer signal Facilities requirements Electrical supply: 12 V rechargeable battery Network interface (PN 9753-04xx) Network: Standard LonTalk® Protocol Data transmission: 78 kBit per second Wiring topologies: Free, (e.g. bus, star, loop or mixed) Wiring: Shielded (tinned copper braid)；4 wire cable；(2 x 2 x 1.0 mm / 17 AWG) Alarm relay outputs Contacts: 3 x SPST Max. ratings: 250 VAC / 30 VDC, 2 A Analog interface (PN 9753-02xx) Interface: 4-20 mA Fault range: 0 ... 2 mA Warning mode: 2.8 ... 4 mA @ 0.1 Hz Maintenace mode: 2.4 ... 4 mA @ 1 Hz Wiring: Shielded (tinned copper braid)；3 wire cable；(3 x 1.0 mm / 17 AWG) Protection class: IP 30 Overall dimensions: 235 x 150 x 235 mm H x W x D: (9.3 x 5.9 x 9.3 in) Weight: 5.2 kg (11.5 Ibs)
