General Guidelines - Siemens EchoMax ST-H Guia De Inicio Rapido

Introduction
The ST-H transducer operates with Siemens Milltronics
ultrasonic level monitoring products.
The transducer converts the electrical energy of the transmit
pulse from the transceiver into acoustical energy. It then
converts the acoustical energy of the echo back into
electrical energy for the controller.
The transducer face emits acoustical energy that radiates
outward, decreasing in amplitude at a rate inversely
proportional to the square of the distance. Maximum power
radiates perpendicularly from the transducer face on the
axis of transmission. Where power is reduced by half (– 3
dB), a conical boundary centered around the axis of
transmission defines the sound beam, the diameter of which
is the beam angle.
The ST-H transducers have an integrated temperature sensor that reports the air temperature
at the transducer to the controller.
