Sound alarm device pzs 02m. Means of operational and technological communication

Find the right tile for you! We maintain a huge assortment, no matter what to lose, not a single visitor and offer everyone what he likes. Any tile can be selected using a convenient filter in the catalog.

From the point of view of earnings, it is much more convenient for us to always sell expensive Italian tiles, but we understand that not all buyers can afford such a purchase. Therefore, in our assortment there is always a wide selection of tiles from domestic factories and manufacturers from neighboring countries, whose products are notable for their low price. Buy the tile that best suits not only your desires but also your budget.

We, just like you, are very annoyed when managers of online stores do not call us back. Therefore, we always call back, including those cases when we understand that the goods are not available and we will not be able to make a sale. Call us or order online and be sure we will call you back!

As a rule, if you order a tile before lunch, you will be able to receive it the next day. The minimum delivery time in our store is 1 day. Do not keep yourself waiting, order a tile and receive it as soon as possible!

Pay on delivery without leaving your home. For your convenience, we have provided the possibility of payment on delivery, so there is no need to come to us in advance and make an advance payment for the purchase.

Buy tiles at more attractive prices, which allows us to keep a large volume of sales and the absence of gigantic rents for retail space.

The store site has a system of discounts on discount cards, which you will definitely receive upon purchase. Terms

Thanks to a convenient tile ordering system, you can get it without leaving your home. Making purchases online around the clock, you will only have to accept the tiles from our forwarding driver. Payment is made upon receipt of the tiles. Terms of payment

The most common mistake when buying a tile is the wrong calculation, when there is simply not enough of it. And for a store to sell one or two tiles is completely inconvenient and not profitable, and not all stores do this. When placing an order with us, you can count on the fact that we will not leave you later and will bring the missing tile to you. Buy without thinking about mistakes, we will always help to correct them. Terms of delivery

No matter how much we would like to sell more quickly and more, we always honestly warn about delivery times, about the nuances associated with the technological features of the tile, which may affect its use, that each batch of tiles leaving production has its own tone (and the floor also the caliber). Therefore, we almost always manage to keep our promises, and when this does not happen, we try to correct the error as soon as possible.

The most common mistake when purchasing a tile is that the buyer does not calculate the supply of tiles in case of trimming or breaking and acquiring the missing one is a big problem! Our consulting managers will always help you correctly calculate the number of tiles, taking into account the necessary margin for cutting and cutting when laying. Ask us about quantity, we will help!

If you want to return a tile, you can do it within 2 weeks from the date of purchase. And although the tile is a product sold by the meter, the law on consumer rights clearly states that such a product cannot be returned or exchanged. We always, without problems, accept a return if we are given it in full in the volume in which we sold it.

• Digital indication of concentration of up to 4 components simultaneously
• Light and sound alarm
• Built-in memory with black box function
• infrared port

Operating conditions

Technical characteristics of gas analyzer M-02

Gas analyzer type - Automatic, portable, individual, multi-channel. Sampling - diffusion and forced with a device for forced sampling (separate order). Concentration analysis methods: electrochemical (CO, O2, H2S), thermal catalytic (CH4, CxHy), thermal conductometric (through a high CH4 concentration channel).

Each channel has two settable alarm thresholds.

Alarm thresholds

Alarm threshold values ​​are set when ordering a gas analyzer; the thresholds can only be changed at the manufacturer or regional service centers.

Efficiency of setting indications by channels:

• CH4 no more than 20 s;
• CxHy no more than 20 s;
• O2 no more than 30 s;
• CO no more than 45 s;
• H2S no more than 45 s.

Gas analyzers of versions 01, 02, 06, 07 are marked with explosion protection PO ExiasI X/1ExiadIIBT4/H2 X, versions 03, 04, 05 - 1 ExiaIICT4 X. Degree of protection against external influences IP54.

Power is supplied from a built-in battery pack with a voltage of 3.8 to 4.2 V. The operating time without recharging is at least 70 hours.

Dimensions gas analyzer M-02: 132 x 67 x 25 mm. Weight 190g. The service life of the sensors is at least two years.

The gas analyzer has two types of memory:

Archival memory- serves to record measurements in automatic mode with reference to real time. Data on the results of methane measurement, the facts of turning on the gas analyzer, the appearance of errors "E1" ... E9, and the discharge of the battery are entered into the memory. The amount of memory is sufficient to collect information for the last 60 hours of operation with an interval of 2 minutes.

Memory of episodic measurements- data is entered at the command of the operator. AT this species The following information is stored in the memory: gas concentration, ambient temperature, time and date, error facts "E1"..."E9". Memory capacity - 4000 records.

All data stored in the memory of the M-01 gas analyzer can be transferred to a PC via the infrared port.

Photo and video receivers require CCD arrays containing many lines. There are a number of designs of such matrices and ways to "interrogate" them.

1. M CCD with frame buffering

Full frame sensor

"Vertical" serial shift registers, components parallel, are called columns CCD matrices, and their work is fully synchronized. The two-dimensional array of photocurrents of the CCD array is simultaneously shifted down one row, and this happens only after the charges of the previous row from the serial shift register located “at the very bottom” have gone to the amplifier.

2. M CCD with column buffering

Specially for video equipment a new type of matrix was developed, in which the interval between exposures was minimized not for a couple of frames, but for a continuous stream. It also uses a buffer parallel shift register whose CCD elements are hidden under an opaque coating. Its columns are "shuffled" between those of the main register. As a result next to each main register column is a buffer column, and immediately after exposure photocurrents do not move "from top to bottom", but "from left to right"(or "right to left") and all in one working cycle fall into the buffer register, completely freeing the PY for the next exposure.

18. Fiber optics. Physical effects used in fiber optics. Examples of the implementation of fiber-optic devices and systems.

Fiber optics is a branch of optics that deals with the transmission of light and images through light guides and waveguides of the optical range, in particular through multi-core light guides and bundles of flexible fibers.

Basic physical ef-t - effect of total internal reflection - internal reflection, provided that the angle of incidence exceeds a certain critical angle. In this case, the incident wave is completely reflected, and the value of the reflection coefficient exceeds its highest values ​​for polished surfaces. The reflection coefficient for total internal reflection does not depend on the wavelength.

Mirrors and filters A mirror is a component that reflects radiation of a certain frequency with a certain reflection coefficient. The filter, in turn, passes radiation of a certain frequency, usually in a narrow frequency range, and absorbs or scatters the rest of the radiation.

Combiners and Splitters Represent two parallel fibers, devoid of a sheath and in contact with each other. The contact and fixation of the fibers is achieved at high temperatures - above the melting point of the fiber. Thus, sections of the fibers are fused together.

Active fiber A fiber capable of amplifying or generating a signal at a specific frequency.

passive fiber A fiber that does not have reinforcement properties. Used to connect fiber optic components to each other, as well as to increase the overall length of the optical circuit, if necessary.

Pump Diodes As in the case of conventional lasers, pumping of the active medium is necessary to start amplification and generation. Semiconductor laser diodes are used to pump active fibers.
