4.6.2 Sta-Dry™ Option
(Modification 9128)
In some applications, condensation or ice can build up
on the transducer face causing a reduction or loss of the
acoustic signal. The Sta-Dry option maintains the
temperature of the transducer face at a level that
prevents condensation or ice from forming. The Sta-Dry
option consists of a heating element in the face of the
transducer and the temperature control unit close
coupled to the ultrasonic transmitter housing.
