complete protection from harsh environments. Internal hermetic sealing is used to
provide measurement of absolute pressures (PSIA) or pressures referenced to a
sealed chamber (PSIS).
Underwriters Laboratories has
approved the SA as a component in float
and pressure-operated motor controllers
(File #E93356). The SA produces a high
level voltage output of 1-6V from an
unregulated supply. It is fully calibrated
and compensated prior to shipment, and
is field interchangeable.
