Mô tả tổng quan về cảm biến mức siêu âm Finetek EAX:

The ultrasonic level transmitter is a non-contact,
low-cost and easy-to-install measuring device. It
can be applied to most industrial applications for
both solids and liquids. Most important aspect of is
that it is easy-to-install and low maintenance due
to no moving parts.

Nguyên lý hoạt động của cảm biến mức siêu âm EAX Finetek:

During operation, the device emits a wave to the
medium to be measured. The wave reflects off the
surface and moves back to the device where a
transducer calculates the distance. The distance is
based on the time interval between transmission
and reception of the wave. D= (334.1+0.6t) x T/2,
where the D = the transmission distance; t =
temperature; and T= transmission time.
With 4~20mA output, it can be connected to the
PLC,DSC and SCADA systems. In addition, it is
also equipped with exclusive PULSE and AGC
(Auto Gain Control) echo tracking technology to
ensure accuracy and precision even in the
harshest environments.
