9) Was created the new product Industrial Power Sources Ferrum, compact and technically forwarded.
Were developed in April 2023. Since June is holding a serial manufacture preparation on July. There are used the technical characteristics of highest level. The non-stop usage equipment. A case from the short stainless steel tube 18 mm diameter with arbitrary working orientation. The sources represent a durability reserve at normal conditions up to 20 years. Provide the highest levels of dust and water protection, intrinsic safety protection, seismic protection, vibrio and mechanic shocks sustainability, electromagnetic compatibility, 2,5 kV level galvanic division of inputs-outputs of source, also of inputs-outputs of connecting external interface RS485.
Three variants of execution: 1) power 0,3 Watt, 2) power 5 Watt, 3) power 0,3 Watt with six alternative power sources, included without external supply.
The sources belong to unrepairable products on GOST 25804.2, apply without work preparation, of moment readiness. An overheating and short circuit defense, of input and output defense from impulse noise (high frequency1filters and voltage limitation).
Interface speed till 1 Mbit/s. Interface is available to be used as a repeater for elongation of connectivity distance.
At exploitation in conditions of hard electromagnetic noise or at a connective cables length 50.. 1000 m or more it recommends to use the screened cable. Mechanic force applied to cables is not more 1 Kg.
The working temperature range -100.. +85°C at sources montage with lead solder or -70.. +85°C at montage with lead-free solder (execution marking PF). The solder volume do not exceeds 0,5 mm3 in sources of 1 and 2 executions, 2 mm3 in 3 execution.
the development news of year 2022:
1) prepared a price for 17,5 thousand temperature Ferrum executions, useful and compact for operative work and production selection, occupies single page A4;
2) started the works on expanding sensor transducer only from cable also to Wi-Fi and Internet, for a reason to organize the sensor possibility to send the time-attached data to necessary internet addresses;
the development news on the last 6 months, 2-nd part 2021:
1) the detailed specification of customer desires realized due the high constructive unification; sensors represent by 32 standard size types in 17 500 executions:
– class accuracy A on repairing category of mechanical executions 1-st and 2-nd with weather range –40.. +60 °C, with measurement ranges –40.. +60 °C, ..+170 °C, ..+200 °C;
– classes accuracy S and P on repairing category of mechanical execution 1-st with weather range –40.. +60 °C, with measurement ranges –40.. +60 °C, with measurement ranges –40.. +60 °C, ..+170 °C, ..+200 °C;
– class accuracy A on repairing and non-repairing categories of mechanical execution 3-rd with weather ranges –40.., –60.., –100.. +85 °C, with measurement ranges –40.. +85 °С, –60.. +85 °С, –40.. +200 °С, –60.. +170 °С, –60.. +200 °С;
– class accuracy A on repairing and non-repairing category of mechanical execution 3-rd with weather range –100.. +200 °C, with measurement ranges –100.. +200 °С;
2) unnecessary optional automatic sensor heating in the difference from analogs and competitors was additionally decreased in 25 times and reached 100-time advantage of Ferrum, maximum 0,01 Watt at weather –60 °C, rises on weather temperature lower –40 °C; higher reliability;
3) automatic sensor heating at weather till –100 °C, maximum 0,03 Watt; a minimal weather temperature on the Earth reaches –98 °C, so the weather sensor temperature –100 °C is really actual;
4) used a new etiquette type with a black laser writing on the cylindrical surface stainless steel plug of construction with a burning depth 0,1 mm, the highest etiquette quality, accuracy of execution, un-washable, un-erasable, operational time forever; see photo;
5) decreased a transducer RS485 diameter on 20%;
6) erased circuit of a sensor heating, now a maximum 4-wire sensor connection (interface 2 + power 2 + screen 1);
7) new soldering material with a temperature 150 °C;
8) the printed boards renovation with 100% gold coverage of all wires surface, high reliability, montage quality, operational time;

10) a new temperature measurement range from –100 °C, not yet certified.
11) voltage supply range of transducer RS485-USB (RS485-RS485) expanded to value +2.. 15 V;
12) simple in use and free of charge user program for automatic operational control, diagnose of sensor groups and replacement of out of order with reserves; decreases a price of initial montage works ~ on sensor cost and also of technical service.
PAGE from the recent Enterprise history
As a material sample of our work supplies the 16-page boocklet 2014 rus load with more early developments of our specialists. Comments:
