Continuous conversion of signals from resistance thermal converters of the type TP, TM with the standard characteristics 100M, 100P, Pt100 under GOST R 8.625–2006, thermal couples of the types TKhA(К), TKhK(L) under GOST 6651-2009 into the unified current signal 0...5 mA, 4...20 mA.

Measuring converter modifications are different from each other: input/output signal type, primary converter type, explosion protection availability.

Measuring converters are manufactured for one measurement range and have one measurement channel.

  • High conversion accuracy;
  • Low cost;
  • Output current signals 0...5 and  4… 20 mA;
  • 3-wire connection diagram of thermal resistances;
  • Cold junction temperature compensation for thermal couples;
  • Opportunity of adjusting the conversion range start and end;
  • Wide operating temperature range from -50 up to +85 °С.

Manufactured in accordance to TC 4218-004-51465965-20033

The power supply of measuring converters with the general industrial purpose is conducted from the power supply units of the series BP, BPM (power supply units are not included in the contents of delivery) with the output voltage 18...36 V.

The power supply of measuring converters in the IS version is conducted from the IS power supply units of the series BPDM-Ex (power supply units are not included in the contents of delivery) having the explosion safety category “IS circuit of the level ia”, subgroup IIC with the parameters: Uo = 24 V, Io < 120 мА.

IS circuits

Measuring converters can be manufactured in the IS version by the order.

Input IS circuits in compliance with the requirements set in GOST 30852.0-2002, GOST 30852.10-2002 have the intrinsic safety level “ia – extra-explosion-proof” with the parameters presented in the Table below for the explosion-proof electric equipment of the subgroups IIC.
