Matched pair of resistance thermometers, PRTDM 202
Matched pair of resistance thermometers, PRTDM 202
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.
mounting elements are designed for nominal (rated) pressure 1.0 MPa
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
