5.5 Temperature gauge
The temperature gauge (Fig. 7) is supplied to indicate the dielectric fluid temperature in degrees centigrade at
thetopoftheoilcolumn.Thegaugeconsistsoftwoneedles(onewhiteandonered). Thewhiteneedleisthe

be reset by turning the knob on the front of the gauge face.
The temperature gauge consists of a long thermocouple that extends into the tank inside a protective
thermocouple well. The isolation between the thermocouple and the dielectric fluid facilities the removal and
replacement of the gauge without draining down the dielectric fluid.
The temperature gauge can be equipped with either one or two SPDT alarm contacts for remote monitoring or
fan control. These alarm contacts are factory set but can be adjusted if desired.
