01.12
01.11 temperature sensors are designed for temperature measurement in gaseous media, natural gas combusion products, and gas flows in main gas pipeline compressor stations at gas flow rate up to 70 m/s in front of protective shield of sensor working end. 01.11 sensors can not be dismantled. In 01.11 with terminal head in form of extension lead, temperature-sensing element is located outside of protective tube for the length of Ê. Thinned part diameter (d1) is equal to 5mm (7mm for CTL with two hot junctions). Fitting thread type should be specified in order.
01.14 temperature sensors are designed for temperature measurement in pulsating gas flow. 01.14 sensor can be dismantled for temperature-sensing element replacement. Fitting is welded to thermowell. Maximum allowable flow rate is calculated on the basis of density and measured fluid temperature. The flow rate should not exceed 170 m/s.
01.15 temperature sensors are designed for blast-furnace and inwall temperature measurement. The screw is intended for easy thermocouple dismantling.
01.12 and 01.13 temperature sensors are designed for gas flow temperature measurement. These sensors are noted for quicker thermal reaction as compared to 01.06, 01.08. Sensors can not be dismantled.
Limit gas flow rate of 01.12 and 01.13 sensors depends on thermowell material, probe length, mobile fluid immersion length, fluid temperature and density. Example of maximum speed for 01.13 modification with 10Cr17Ni13М2Т steel thermowell at fluid density 10 kg/cm2 and temperature 600°С is given in the table below on condition that sensor immersion length is equal to probe length.

Flow rate at other operating conditions or sensor modification can be calculated on customer's request.
Sensors can be of explosion protection type 0ExiaIICT6 X or 1ExdIICT6 according to GOST 30852.10-2002. For further details see "Alternative designs & Ordering information" below. Terminal heads can be equipped with transmitters with 4-20 mА DC output signal and/or digital signal via HART, PROFIBUS-PA, FOUNDATION Fieldbus protocol. It is recommended to use heads of 16, 23, 28 modifications for easy wire connection to transmitters. Terminal head can be equipped with standard or special-purpose cable gland. For further details see "Alternative designs & Ordering information" below.
