Manometr-Kharkiv, Private Join Stock Company

Manager - Volodymyr Lebedynsky

The close corporation "Manometr-Kharkiv" was created in 1997.

The main sphere of business:
- production of pressure sensors for different industries of national economy.

The staff of the corporation has long-term experience of work in this area.

In 1999 the corporation started the commercial production of the first series of transmitters SAFIR of own development - pressure transmitters Safir, which are used instead of transmitters Sapphire-22 and their Russian clones.

"Safir" panel products:

"Safir" line of pressure sensors includes "Safir", "Safir-M" and "Safir-MX". The ground of the line are original measuring blocks devoid of the faults appropriate to the devices of "Safir" line and their analogues. Shift from diaphragm-leverage transforming scheme of the in parameter and other solutions enabled to create a solid base for the further development of the whole sector. Propriety of the choice is proved by the fact that today "Safir" sensors are allowed for using in all basic industries of Ukraine instead of "Sapphire" and their Rusian analogues.

"Safir" pressure sensors
"Safirs" are designed for uninterruptable measuring of the absolute and excess pressure, exhaustion, pressure-exhaustion, pressure differentials, hydrostatic pressure of fluid and gaseous media. Subsequently the device thransforms the measured figures into a unified electric signal of direct current.
The sensors can be utilised in the systems of automated control, regulating and control for production process. They are also used for counting of gas and fluid consumption, including commercial consumption.
"Safir" has the following types of performance:
- extremely explosion-proof;
- explosion-proof;
- explosion non-proof;
- on resistance to climatic impact - U2*, UHL 3.1*, Т3*;
- on materials - 02, 11, rustproof;
- oxygen
Limits of measurement (range of measurement) of "Safir" sensor: 63 Pa - 100 MPa.
- Accuracy: 0,2 %; 0,25 %; 0,5 % of span.
- Rangeability 10:1.
- Output: 0 - 5 mA (5 - 0 mА); 4 - 20 mА (20 - 4 mА) readjustable in single unit. Tuning of output signal 0-5 mA to 4-20 mA and vice versa in a single device is available.
Drawbacks coherent for "Sapphire-22" are minimised in the device. There was decreased additional inaccuracy connected with the impact of temperature and static pressure.

Now pressure transmitters Safir are widely used in all industries of Ukraine: nuclear power plants, thermoelectric power stations, enterprises of engineering and chemical industries, oil-and-gas producing and refining companies, ironworks, non-ferrous metallurgy, food and drink enterprises. The largest worldwide-known enterprises of Ukraine are the customers of the corporation.
In the middle of 2000 the corporation began the development of a new series of transmitters SAFIR - pressure transmitter Safir-М with microprocessor data handling, which most closely corresponds today's and future customer's requirements and possesses the best ratio "cost - quality". New devices have smaller main and additional temperature error in a wider range of adjustable span, better stability and higher overpressure resistance.
The pressure transmitters Safir-М have successfully passed the State attestation, their release began in the second half of 2002.
Having own development function, the corporation is able to solve independently not only the task of device diversification (since 2000 the hydrostatic pressure transmitters are produced, since 2001 - oxygen tolerant transmitters), but also the task of product line extension. In addition to pressure transmitters, the corporation designs and produces all devices required for pressure measurement - power supplies Safir-BP, 3-valve manifold Safir-VB and separating seals.
The experts of Manometr-Kharkiv solve also any particular customer-specific tasks, bound with pressure measurement.

Pressure transmitters Safir-M
The accomplishment of all potential possibilities of sensor modules Safir can be reached only at complete mutual correspondence of all sites defining characteristic of the instrument. Pressure transmitter Safir-M is the further development of a series. Its design contains a number of original technical solutions improving quality of the instrument and opening the way to technologies of the future.
New transmitters are more accurate (accuracy 0,15; 0,25 % in full temperature range) and more reliable, possess better stability (2 years calibration interval), have increased life expectancy (14 years), overpressure resistance and extended functionality (rangeability 1:40, smooth adjustment of 'zero' and 'span' within ±100 % of URL, changeable output signal: linear, inversed or square-root).

Power supply Safir-BP
Safir-BP is intended for power supply of thermalphysic parameters transmitters (e.g. Safir, Sapphire-22М, Metran) in explosion-proof plants including NPP by stabilized direct current.

- The device is protected against overload and short-circuit. While protection short-circuit current is not more than 0,1 мА.
- After removal of overload or short-circuit the device automatically restores its characteristics through 3 - 4 s.
- The device is equipped with operation and emergency situation status indicators.

Up-to-date element base and circuitry provide high reliability of Safir-BP at excellent mass & dimensional characteristics.

"Safir-VB" valve blocks
"Safir-VB" valve blocks are designed for commutation of impulse lines with conditional pressure up to 40 mPa, for instance from a restriction device to pressure differential sensor. Performance on materials 02. "Safir-VB" valve block has an equalizing valve and can be used for sensor calibration (zero position reduction) at the place of exploitation.

Now "Safir" sensors are used in all Ukrainian industries, including such major enterprises as "Zaporozhye NPP", "Rivne NPP", "Yuzhno-Ukrainska NPP", "Khmelnitsky NPP", Mironovka cogeneration plant, Ladyzhynskaya cogeneration plant, Uglegorskaya cogeneration plant, Tripolye cogeneration plant, "Cherkassy Transgas", "PrikrapatTransgas", "LvivTransgas", "Poltavagasdobycha", "ShebelinkaGasdobycha", "DonetskAvtogas", "Stirol" OJSC, "Titan" public joint-stock company, "Crimean Soda Plant" OJSC, "Khersonneftepererabotka" JSC, Sumy R&P Complex named after Frunze, "Zarya-mashproekt", etc.

The company was awarded Diploma of Laureate at the national contes "Vyshcha Proba" (Highest Grade).
