Fixed natural gas (CH4) leakage alarm [Lyla (0531-58669819 15269173085) For details, please call my company] the concentration of methane gas alarm wire alarm; handheld gas leak detector can be long-term monitoring of gas in the explosion scene. The detector is installed in the explosion scene, the controller wall hanging someone on duty in the duty room and other places, use shielded cable to connect the two. Gas concentrations in the environment when stationary gas alarms to meet or exceed preset alarm value, the alarm signal to the controller through shielded cable controller immediately issued a sound and light alarm, toxic gas alarm can start row the wind device or closing the solenoid valve to cut off the gas source, in order to achieve the purpose of security. Alarm control host fixed natural gas (CH4) leakage alarm methane alarm should be installed in the fire center fire duty room, instrument room, boiler room, charging room, plant and other non-explosion sites manned control unit can control the host, tour view multiple detectors, each detection point gas concentration, control host and the detector using the bus system or sub-wire connection, easy to install distribution network, centralized control of multiple control points, when the gas concentration in the environment or exceeds the preset alarm value, alarm issued immediately audible and visual alarm to remind the user to take safety measures. Fixed natural gas (CH4) leakage alarm features: 1. Use of high-speed CPU processor, can be quickly and accurately processing system tasks, to ensure the reliability of the system 2.LCD LCD screen can be displayed in real time the concentration of the detector, state 3. Use digital signal transmission, high reliability 4.2 programmable relays, passive long to open, normally closed contact, contact capacity 240V 5A 5. modular structure design, easy maintenance 6. achieve local control by the computer and remote monitoring of detector running state data can be stored permanently. import gas sensor, high precision, strong interchangeability, high reliability 8. proof design suitable for the the dangerous conditions 1,2 district 9 small size, installation The simple 10. modular structure design, easy maintenance fixed natural gas (CH4) leakage alarm Technical parameters: 1.
