Combustible gas detector explosion proof Ex d IIC T6
Explosion Proof Dual IR Flame Detector relay output
Fire alarm relay output Fault relay output IR2 EXdIICT6 Product function and composition A705/IR2 can be applied to the need to monitor the implementation of the fire place, quickly found that the fire may cause the burning flame, issued in a timely manner Fire alarm. A705/IR2 is converted to electrical signal by two infrared pyroelectric sensors which work in different bands. Signal input industrial computing chip for comparison, operation and processing, with the detecter&anysafe II Ir dedicated intelligent control software, you can Send out a fire alarm in time. A705/IR2 uses the aluminum die-casting flameproof shell, has good protective properties and explosion-proof, corrosion resistance, aging resistance, can work for a long time In the indoor, outdoor and all kinds of special industrial places.

Combustible gas detector explosion proof Ex d IIC T6
Gas detector HD-T600 is used to continuously monitor the density of combustible gases in the air for a long time, and is installed in flammable and explosive places where the working environment is bad and the staff are not easy to get close to. The concentration is converted to DC4-20mA standard signal output. The gas detector is with LCD density displayer and sound and light on-site alarm. But it should be connected to fire alarm control panel or other types controller for alarm report and surveillance. This HD-T600 industry explosion proof gas measurement tool and alarm device is designed as pwer "I" Point-type combustible gas detector with measuring range of 0-100% LEL, GB3836.2-2000 Explosion. It is designed strictly as per Flameproof "d" electrical equipment for explosive gas environment and has high stability. It has features of Low power consumption, anti-interference. Flammable gas detectors can be widely used in petrochemical industry, oil fields, oil depots and liquids, chemical plant, gas station, coal mine, environmental protection and other departments. It is an ideal monitoring instrument to ensure property and personal safety. Detector: 1. Measurement object: flammable volatile liquid 2. Measurement range: 0-100% LEL 3.

Alarm Bell Ex type industry security Fire fighting
JDJL-2 explosion-proof fire alarm bell (abbreviated as alarm bell) is a non-coding alarm bell. It is suitable for installing in explosive gas environment with T6 temperature group of level II C (or II B). When an accident or fire occurs at the production site, the control signal sent by the fire alarm controller starts the alarm circuit and sends out sound alarm signal to complete the purpose of alarm. This product can also be used with manual alarm buttons to achieve simple sound alarm purposes. The alarm bell can be used in conjunction with the fire alarm controller of any manufacturer. The alarm bell has reasonable structure, beautiful appearance, reliable performance and convenient installation. It is a fire alarm device with high reliability and strong anti-interference ability. This product meets the requirements of GB3836.1-2000 "Electrical equipment for explosive gas environment Part 1: General requirements", "GB3836.2-2000", "Electrical equipment for explosive gas environment Part 2: Flameproof"d";". The inspection unit designated by the state has passed the inspection and obtained the explosion-proof qualification certificate. Installation: M6 screw is used to fix the alarm bell on the wall through the installation claw of the alarm bell (the inlet must be facing up). Cable introduction device: The sealing nut is used to press the sealing ring structure tightly. It can be widely used in petrochemical industry, oil fields, oil depots and liquids, gas station, coal mine, environmental protection and other departments.
