Technical characteristics

   Revolution counter PO1830.1

    Also, this device can be called: PO18301, PO1830-1 PO1830 1, PO-1830.1.

    PO1830.1 revolution counter - a device designed to determine the total number of revolutions of shafts of marine engines and issue frequency signal proportional to the frequency of rotation of the shafts. Usually used in conjunction with devices K1830.1 tachometers.
    The total number of revolutions of the shaft is determined by the number of periods of electrical frequency signals of primary converters electronic tachometers.
    The composition includes a counter PO1830.1 FA1881.1 separation device and a display device FSCH1882.1. The apparatus is intended for separating the frequency transform signals from the sensors into control signals counting mechanism arranged in the display device.
    The device adds the number of revolutions regardless of the direction of rotation of the shaft can be used with a single sensor and two having a frequency signals phase shifted by 90 °.
    Body rev counter splash-proof, the device shakeproof.

    Specifications instruments tachometers PO1830.1

    Number of rotor teeth - 6-300.
    The number of bits of the counter - 6 or 7.
    Maximum speed - 500-4000 rev / min (depending on the number of rotor teeth and range tachometer).
    View performance counter PO1830.1-reversible.

    Power consumed by the counter from the power supply - 25V · A.
    Voltage - 220V, frequency 50 Hz ± 3 and 400 ± 20Hz.
    Coefficient of voltage waveform distortion - no more than 10%.
    Insulation resistance of electrical circuits - at least 20MOm.

    Dimensions - 120x40x131 mm.
    Weight - no more than 0.6 kg.
    Average life - 10 years.
    Basic error counters do not exceed the values ​​given in Table 1, according to testimony, depending on the meter constant.

The company takes an active part in such procedures as electronic bidding, tender, auction.

 

If there is no site in the descriptive information you need on the device you can always turn to us for help. Our qualified managers will update for you on the technical characteristics of the device from its technical documentation: user manual, certificate, form, operating instructions, diagram. If necessary, we will take a photo of your device, or a device stand. You can leave feedback on the unit purchased from us, the meter, the device, indicator, or product. Your review for your approval will be published on the site without contact information.

Description of the instruments taken from the technical documentation or technical literature. Most pictures of products made directly by our experts prior to shipment of goods. In the description of the device provided the main technical characteristics of the instrument: nominal measuring range, accuracy class, scale, supply voltage, size (size), weight. If the site you see the discrepancy device name (model) specifications, photo or documents attached - let us know - you will get a useful gift with-selling device.

While the need to clarify the overall weight and size or the size of the individual meter you can in our service center. If you need our engineers will help you choose the most complete analog or a suitable replacement for the device you are interested. All counterparts and replacement will be tested in one of our laboratories with the full compliance to your requirements.

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction! The price of precious metals will depend on their value and mass in grams.
