Dial type thermometers are designed to measure, Indicate and control the temperature of a specific applications, like Transformers oil , Generators, Bearing temperature monitoring etc…
DIAL TYPE THERMOMETER 4006 H
DIAL TYPE THERMOMETER 4006 H
SERVICE DETAILS
Dial type thermometers are liquid filled in the closed system and DTT consists of Bulb assembly, capillary and Expansion bel-lows. If the temperature changes, the internal pressure of the thermometer changes as well. The pressure is transferred through capillary to a pointer shaft and thus the temperature values are indicated on scale.
OTI and BTD works without external power for its operation and indicates corresponding oil temperature on front panel.
WTI construction is also similar to OTI, in addition to that CT are provided to measure the winding temperature plus winding temperature above hot level, i.e the hot spot temperature.
WTI are provided with gradient adjustment through a shunt for CT secondary in-put (1A to 5A)
