Honeywell - Aquastats
Popular thermostats for a variety
of water heating applications.
Honeywell manufactures a comprehensive range
of Aquastats for controlling
heating systems. These sensitive, fast response devices are
available in either direct, panel or surface mount versions.
The liquid filled sensing element, including well or sensor
assembly, responds to temperature changes of water in a heating
system.
The sensor assembly, used on the surface mounted
Aquastat,
envelopes the sensing capsule by means of an aluminium heat shield
for better heat conduction, an insulator of glass-wool and a
mounting bracket.
