4 Dual switch element multiply single switch element value by 1.6 for
approximate deadband.
5 Set and reset points must fall within the adjustable range.
Temperature Switches
B-Series temperature switches feature
a SAMA Class II vapor pressure thermal
system. This system provides quick,
accurate response to process tempera-
ture changes with negligible ambient
temperature effects. This is inherent in
the design due to the precise relation-
ship that exists between temperature and
pressure according to the vapor pressure
laws. A wide selection of sensing bulb
and armored capillary lengths is avail-
able. The vapor pressure system design
features small bulb sizes, making instal-
lation easy and cost-effective.
All models feature ±1.0% percent of
span setpoint repeatability with very high
overtemperature ratings.
These standard designs perform well
in applications where shock and vibra-
tion could be a problem and should be
used with Ashcroft thermowells for bulb
protection and ease of installation and
maintenance.
