About Milltronics’ Transducers
The Echomax XPS F series of transducers operates in association with
Milltronics ultrasonic level monitoring products.
The transducer operates by converting electrical
pulses that are provided by the transceiver into
ultrasonic pulses. When transmitted, these
ultrasonic pulses reflect from the material surface
and echo back to the transducer. The echo is
converted back to an electrical signal, and is
interpreted by the Milltronics tranceiver using
our proven Sonic Intelligence™ algorithms.
The effective acoustical energy is emitted from
the transducer face and radiated outward,
decreasing in amplitude at a rate inversely
proportional to the square of the distance.
Maximum power is radiated axially
(perpendicular) from the transducer face in a
line referred to as the axis of transmission.
Where power is reduced by half (– 3 dB), a
conical boundary defining the sound beam,
centered about the axis of transmission, is
established. The diametric measurement of
the cone in degrees defines the beam
angle. Impedance matching techniques are
used to optimize the transfer of power from the transducer into air and vice
versa.
The XPS F series transducers incorporate an integral temperature sensor
that reports the air temperature at the transducer to the transceiver. The
connection is transparent, in that both the ultrasonic and temperature
components of the transducer use the same leads.
Hazardous Area Applications
The Echomax XPS F series of transducers can be used in hazardous areas.
For the XPS 10 F series transducer, a hazardous seal must be used to suit
hazardous area classification. This seal is
not
supplied by Milltronics.
The XPS 15 F comes equipped with a stainless steel coupling suitable for
use in hazardous locations.
