Series DBT Digital Solar-Powered Bimetal Thermometer

Specifications - Installation and Operating Instructions

The Series DBT Digital Solar-Powered Bimetal Ther­mometer takes the guesswork out of temperature mea-

surement. The 3-1/2 digit LED display is easy to read and
provides resolution to 0.1°F. The adjustable angle can be
mounted in virtually any position. The engineering units can
be selected in the field by removing the back cover.

Operation

Series DBT thermometers are solar powered and are con­tinuously operating. Series DBT thermometers must be
used in environments where there is adequate light available
to power the unit. To obtain a temperature reading on the
Series DBT, simply insert the stem of the thermometer into
the process being measured.
Thermowells are recommended in all high pressure, flow,
and corrosive media applications. Thermowells protect the
Series DBT thermometer from damage and premature fail­ure. Additionally, thermowells allow for easy removal of the
DBT draining the process media.

Unit Selection

The Series DBT allows users to field select the readings to
be measured in ˚F or ˚C. Remove the rubber cap on the rear
of the unit. The unit switch will be to the right for ˚F and to the
left for ˚C. Refer to Figure A.
