Gas Alarm Detector Features ◆ measurement accuracy imported sensor sensitive components, with high accuracy, interchangeability, high reliability. ◆ digital compared to analog signal 4-20mA standard current signal, without first for commissioning before the exchange may at any time freely exchange gas detector position, easier to maintain. Advantages of high accuracy, transmission distance, interference well. ◆ industrialized docking system may need to be adjusted user signal output according to the connection with the DCS, PLC and other industrial automation systems engineering. ◆ Explosion-proof can be used in factory conditions 1, 2 dangerous places. ◆ internal movement with easy maintenance kit form, field maintenance, replacement components to complete. ◆ structure of the gas detector detector housing die-cast aluminum material, dual-chamber structure designed to avoid accidental water, nearly dust, corrosion, and failure phenomenon, small size, easy installation. ◆ sensors Protective sensors detect a head portion made of stainless steel, effectively it plays the role of anti-corrosion; too sensor mesh stainless steel particles, good air permeability. Gas alarm detector technology parameters Certification ◆ Explosion-proof: Exd II CT6 ◆ Type approval: National Fire Electronic Product conformity assessment center ◆ Application Standard: GB15322.1-2003 electrical ◆ Power supply: DC12V-30V ◆ Signal: digital signal ◆ Wiring Terminals: for wire cross-section 0.5 ~ 2.5mm2 ◆ connection cable: 3 × 1.0mm2 ◆ Connection: Three-wire ◆ Accuracy: ± 5% FS ◆ Response time: less than 30s environment ◆ IP rating: IP65 ◆ Temperature range: -40 ℃ ~ 65 ℃ (catalytic combustion) | -40 ℃ ··· 65 ℃ (electrochemical, non-permanent) ◆ Humidity: 10 ~ 95% RH (non-condensing) ◆ pressure range: 86 ~ 106KPa ◆ Storage temperature: - 40 ℃ ~ + 65 ℃ ◆ Transmission distance: ≤1200m detection ◆ Detection of gas: flammable% LEL | hazardous ppm ◆ detection method: natural diffused ◆ Detection range: 15-25m2 ◆ Body Material: Aluminum Material ◆ Anti Dust Cover Material: Stainless steel dust network ◆ Anti connecting thread: G1 / 2 "◆ Weight: 1.5kg ◆ Installation: mounting bracket, tube, wall mounted ◆ Dimension: 126mm (L) × 93mm (W) × 62mm ( H) ◆ matching controller used: DN-K1000-2, DN-K1000-6 type gas alarm controller ◆ gas detectors should be installed in a gas leak prone areas and the specific location should be detected according to the proportion of gas relative to air decision 1, when the detected gas is heavier than air proportion of gas detectors should be installed from the ground (30 ~ 60) cm at the sensor site and down. 2, when the proportion of gas to be detected is less than the proportion of air, gas detectors It should be installed at a distance ceiling (30 ~ 60) cm at the sensor site and down ◆ fixed gas detector for detecting gas ◆ one detection range: 12-15 square combustible gas catalytic combustion sensor (% LEL), toxic gas electrochemical sensors (ppm, 10ppm) ◆ In order to use gas detectors and gas detectors to prevent faults, do not install in the following locations: 1. place directly affected by steam, smoke effects; 2 , to air intake, fan, door, air volume flow and other big place; 3, water vapor, water droplets in many places (relative humidity ≥95% RH); 4, the temperature below -40 ℃ or above 65 ℃ place; 5, strong electromagnetic fields.
