Matched pair of resistance thermometers, PRTDM 101
Matched pair of resistance thermometers, PRTDM 101
These units are designed for temperature difference measurement, and also for heat carrier temperature measurement in heat meters and other heat energy control units in open and close heat supply systems.
Pair of resistance thermocouples PRTDM 102 can be completed with thermowell UNKJ 011 or UNKJ 012
mounting elements are designed for nominal (rated) pressure 1.0 MPa for PRTDM 101
response time does not exceed
16 s – for insertion part diameter equal to 6,0 mm;
20 s – for insertion part diameter equal to 8,0 mm
protection sheath material S10 – steel 12Cr18Ni10Т

PRTDM 10х-010 - ХХХ - TC - Cl. - d - L
PRTDM 101-010 - М20 - Pt500 - В2 - 8 - 320 – matched pair of platinum resistance thermometers, modification 101-010 with polymeric terminal head, calibration Pt500, tolerance class В, 2-wire configuration, outer diameter 8 mm, insertion length 320 mm; mounting elements: ring 18 mm diameter, threaded fitting М20х1.5.
At the time of order it is recommended to specify actual minimum heat carrier operating temperature and minimum measuring temperature difference.
