Fixed chlorine detector HN-GD

1 Overview 1.1 Features Fixed chlorine detector HN-GD electrochemical sensor or catalytic combustion sensor with fast response time, stable and reliable performance, low drift, long life characteristics. Site display data, you can communicate with the computer. Three-wire or four-wire output output, simple operation, easy installation and maintenance. And on-site calibration. (Note: The three-wire output signal (4-20) mA, four-wire output signal RS485, electrochemical gas sensor, catalytic combustion sensor detects combustible gas) 1.2 Main purpose and scope of fixed chlorine detector HN-GD mainly used for continuous measurement of the concentration of various toxic gases and flammable gas concentrations at ambient conditions, and due to the natural gas gathering easily cause an explosion, poisoning and other dangerous places, such as metallurgy, chemicals, gas stations and other industries. 2 Structure and working principle of the instrument using digital chip sensor signal acquisition, via an amplifier circuit into an output signal. And then calculated the data processed by the MSP430 microprocessor, and display and output signals with the company's CPR-E Series gas detection alarm supporting component measurement and control system. Instrument by the housing, a circuit board, an electrochemical sensor / catalytic combustion sensors and other components. 3 Main Specifications 3.1 Technical Specifications a) output signal: (4 ~ 20) mA or RS485 b) work: fixed continuous measurement c) response time: ≤60s (ammonia ≤150s) d) basic error: ≤ ± 5 % FS e) Repeatability:. ≤2% f) Operating temperature: -10 ℃ ~ 50 ℃ g) Operating Humidity: ≤93% RH (non-condensing) h) Sensor life: ≥ 2 years i) Power: DC 24V 3.2 sets of a) the instrument 1 set b) a calibration cap c) manual 1 d) Certificate 1 e) Packing List 1 f) Remote Control 1 g) gas detection alarm (optional) 1 3.3 Installation dimensions and weight Weight:? 0.85 kg Dimensions:?
