Thermometers manometrical showing signaling Tm2030sg-1 (with gas filler) and Tm2030sg-2 (with condensation filler) are intended for continuous measurement of temperature of liquids and gases, neutral concerning their impact on steel and copper alloys, and managements of external electric chains from the signaling device. Are applied in various installations and in systems of heat power control where timely information on the reached extreme values of temperature is necessary.
For elimination of influence of a tinkling sound, a podgoraniye and oxidation on operation of the signaling device devices can be delivered in a complete set with URK.
