Appointment and scope.
The thermometer of resistance of KSTV is intended for measurement of temperature of the liquid environment, by transformation of temperature to resistance of a thermosensitive element. KSTV is a set of thermometers of resistance platinum, intended for measurement of a difference of temperatures of the heat carrier in the giving and return pipelines of the systems of heat supply for this purpose coordinated according to individual static characteristics of transformation.
Are applied as a part of metering devices and control of thermal energy in systems of heat supply.
Features of thermometers of resistance
