Iron Sunrise Enterprise.
Temperature sensors of series Ferrum.
The investigation and manufacture of high precision measuring equipment.

Dear Finansist!
For the own manufacturing program we are looking for 10 mln. RUR investment on year duration. The variant of payment: at the end of 12-th month returns 25 mln. RUR or the exact currency equivalent.

Temperature sensors Ferrum exceed the best world known samples practically with all 40 parameters. They represent new and protected sensors, reliably and exactly measuring temperature in complex and extremal working conditions.

  • The main sensors advantages
    • A production differs with high industrial standard A and also in 5 and 15 times more precise sensors. The error limits of measurement in the working conditions of application: ±(0,15+0,002·|t|) °C (class accuracy A of GOST 6651), ±0,1 °C, ±0,03 °C in the set of montage elements for 99,7% of measurements number. An absence of additional measuring error in the working conditions is equal to 2-3 aliquot of additional rise of the sensor accuracy.
    • The sensors Ferrum provide an endurance for an operational term up to 50 years. So there are absent plans on the nearest 20 years of the developed production line modernization. Guaranty is up to 5 years. The announced service life of the sensors Ferrum is based on real Enterprise achievements. Nearly 70% of sensors, manufactured 20 years ago fill themselves not badly and finishing their third average service time. The new sensors have better constructive and technological base and have met the developer’s expectations. Two sensors of accuracy class A were subjected to the tests on influence of 100 thermic blows cycles -40˚C/+60˚C/-40˚C in ambient air with 2-hour excerpt in each condition. So it was modelled 100-year service time of sensors and realized corresponded tests.
    • Minimal time of the thermic reaction. According GOST-6651 a time of 63,2% of a complete indications change at a velocity water flow 0,4 m/s is 1,5 s and in a protective glove 3 s.
    • An equipment of the nonstop application. Voluntary working location.
    • Provided a work on the montage pipelines with a pressure up to 500 atm. and diameter 15.. 2000 mm the precise sensor positioning on a pipeline axis.
    • High protection of sensor and it insensitivity to the complex conditions of exploitation with account of all typical unfavorable influenced factors. The highest levels of dust-and-water protection, intrinsic safety, seismic resistance, electromagnetic compatibility, software defense, thermal inertia, maximal velocity of measuring substance, a readiness time at a power supply start, power consumption.
  • The additional sensors advantages
    • Minimal influence on accuracy of the ambient temperature is provided with construction and sensor adaptation to all specified types of measuring substance.
    • Vibration resistance 5g up to 500 Hz and resistance to mechanic shocks 40g 6 ms/15g 16 ms.
    • Micro power consumption of feeding energy. It could be enough of a single battery size AA for non-stop function of seven sensors during 10 years. It provided the base, when the power source in the traditional representation will not be required.
    • The highest intrinsic safety level 0Ex ia IIC T5…T6 Ga. Allows a work in the atmosphere of hydrogen, the most easy-flammable natural gas with a temperature 80 °C.
    • The electrical field resistance up to 5 kV/m. Insensitivity to 1000 electrical discharges 15 kV with absence of failures and with accuracy keeping during influences.
    • The highest degree of dust-and-water protection IP68/IP66. A stability to a water sinking up to 1 m depth and to pouring water jets of high intensity.
    • Instead of the well-known limitations with measuring by analog cables now is parallel 2 or 4-wire communication of all present sensors in digit by a single communicative cable without noises-distortions to a distance u0 to 5 km.
    • All the temperature questions were organized in one compact unit: a sensor, including metrology. I a case of necessity is available fast sensor replacement with any reserved. An accustomed information about plant numbers of sensors and a strict binding to them for operation already not necessary.
    • A recommended usage of sensors Ferrum in the devices of a complex hierarchy of other manufacturers gives a decreasing of calculating, apparatus power and of calculator in heat energy or in gas volume or in the another purpose unit a decrease of an active phase of required power plus our sensor supply a lot own advantages.
  • An everywhere application, when required temperature measurements, mostly in industry and not only, for autonomic and in-built usage in all spheres of possible sensors application from underground, deep mine up to a sea and universe, geographically from pole to pole, even for apparent as usual applications could be found very useful, and exactly in industry: in transport, including the sea, mining works, atomic objects, metallurgy, construction, water- and heat- supply, electro- and heat- energetics, chemistry, machine tool industry, food industry and others.
  • Construction of sensors Ferrum is measuring pocket of 10.. 1500 mm length with primary transducer Pt1000 on the end and plug with interface RS485, joined with cable up to 90 cm.
  • Interface RS485 in the sensor plug with standard open protocols Hyper terminal Win, Mod-bus. Connector and cable one-piece connection; a cable length is practically unlimited, screened cable recommended, till 200 switching sensors; 6-wire connection – full functional, power not from interface (minus 2 wires), without interface plug heating (minus 2 wires).
  • Power +(3,3.. 5) V, with an interface RS485 cable or separately. Micro power consumption. Typically a feeding current is 3 mkA. An interface switching-off in long work pauses makes an additional multi-time current economy.
  • Possibilities: temperature relay mode, galvanic isolation 2,5 kV, encryption of measuring data, digital filtering of measuring data, delivery in batches with selected accuracy of measurement temperature difference, automatic heating of interface plug on maximum 20 °C at low ambient temperatures (improved reliability, recommended at ambient temperature lower -40 °C), intrinsic safety transducer RS485-USB and barrier RS485-RS485 with galvanic division and stable power 3,3 or 5 V for communication with computer or another devices, wireless connection to the interface, connection to Internet and Wi-Fi.

Dear Customer! Our sensor is a high precision measuring tool. In a case of neat and careful attitude provides the dozens years of unproblematic operation. If you have a necessity to adopt sensor Ferrum to some specific tasks, the Enterprise is ready to study such possibility.
