Formaldehyde gas alarm installation precautions

Formaldehyde gas alarm consists of detector and alarm control host, widely used in petroleum, gas, chemical, oil depot and other toxic gases in the petrochemical industry, to detect indoor and outdoor hazardous locations leak, is to ensure the production and personal safety Important instrument. When there is a toxic gas in the measured location, the detector converts the gas signal into a voltage signal or a current signal and transmits it to the alarm meter. The instrument displays the percentage concentration of the toxic gas explosion lower limit. When the concentration of toxic gas exceeds the alarm set value, an audible and visual alarm signal is generated. The on-duty personnel take safety measures in time to avoid the occurrence of explosive explosion.
Formaldehyde gas alarm installation considerations
(1) The alarm probe is mainly a detection element that is in contact with the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. On the outer surface thereof, platinum, palladium, and other rare metals are attached. Therefore, be careful when installing to avoid damaging the probe.
(2) The installation height of the alarm should generally be 160-170cm, so that maintenance personnel can carry out routine maintenance.
(3) The alarm is a safety instrument, sound and light display function, and it should be installed in the place where the staff can easily see and hear, so as to eliminate the hidden trouble in time.
(4) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument around the alarm.
(5) The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the measured gas density is less than the air density, the probe should be installed 30cm away from the roof and downward; otherwise, the probe should be installed 30cm away from the ground and upward.
JW-100 formaldehyde alarm adopts high-performance electrochemical sensor and sophisticated circuit design to provide high stability and excellent anti-interference ability. It provides on-site alarm and remote alarm function (with the host) for indoor formaldehyde in different degrees of excessive levels. People early warning information.
The main features:
Independent sound and light alarm, easy installation
With the host can achieve remote alarm, and upload the current gas concentration
Beautiful interface, easy operation
MCU microprocessor technology
High-performance electrochemical sensor
When monitoring the concentration of formaldehyde harmful gas reaches the alarm condition, the detector will send a sound and light alarm indication and upload it to the host.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
