Oxygen alarm particular inspection is necessary to check which items
Oxygen alarm, is a use of imported electrochemical sensors for oxygen concentration in real-time monitoring of a security instrument, avoid excessive or insufficient oxygen, and result in hypoxia, dyspnea, poisoning accident. Fixed oxygen alarm is generally composed of two parts oxygen and oxygen gas detector gas alarm controller, and oxygen gas detector on the oxygen concentration detected by the scene, with up to CT6 explosion-proof grade, to achieve the oxygen concentration detected by the core components of a gas sensor ; an oxygen gas alarm controller is placed in the duty room, the lounge has a staff in place, any time convenient to monitor the density value, the timely processing of emergency. Oxygen alarm Features: 1, high-speed cpu processor, can handle the task quickly and accurately, to ensure system reliability; 2, LCD liquid crystal screen display of concentration detector, real-time status; 3, the use of oxygen alarm 485 communication protocols, high reliability; 4, with a programmable relays, passive normally open, normally closed contact, contact capacity 240V / 7A; 5, the oxygen alarm modular design for easy system maintenance. Oxygen Alarm Specifications: Detection of gas: Oxygen Detection range: 0-30% VOL Resolution: 1% VOL alarm: Low reported: 19.5% VOL; overstated: 23.5% VOL Detection principle: Electrochemical sensor mode: Nature Diffusion-type Explosion Proof: Exd II CT6 Protection class: IP65 Output signal: 4-20mA standard signal output or electrical interfaces RS485 protocol: G1 / 2 Operating temperature: -40 ℃ ~ + 70 ℃ Humidity: ≤90% RH Life: . 1 5 - 2 years Alarm volume: ≥70dB Response time: ≤20s connection cables: sub-line formula: GB RVVP3 × 1.5 or RVV3 × 1.5 Bus: GB RVVP4 × 1.5 or RVV4 × 1.5 Communication distance: ≤1000m Certification: Explosion certification, inspection reports, product type approval certificate, certification, and other oxygen alarm fire patrol watch how to do? 1. The device of oxygen inside the complex, and some of the oxygen-rich, some for lack of oxygen, some close to the atmospheric environment. Therefore, specific alarm values ??and generally show the need to distinguish between the actual situation. Galvani general principle of precision about 0.3vol%. 2. atmospheric oxygen concentration is generally considered 21vol%, hypoxia alarm set point at least 18vol%. Life is about 1 to 2 years 3. For the purposes of specific inspection, routine inspection is recommended to consider the following: date, time, plant name, device name, specific location 1 ~ n, display, referring to the normal range, it is determined to check People oxygen alarm Consulting Website: http: //www.jnrtkm.com/proshow.asp id = 380 gas alarm Advisory way:?
