Description
The dial thermometer is used to determine
the ambient temperature at the thermostat
sensing element.
The baumanometer is a squeeze bulb with
a restrictor type shut-off valve. It is used if
a source of air pressure is not available or
if a gradual air pressure change is required
to operate a pneumatic device such as a
valve or damper actuator.
