Description
This 1-channel automatic amplifier from Pantron has
set a new standard for devices of this type. It is an
amplifier with an integrated analysis unit. The
automatic gain setting enables the user to simplify
the installation and work.
The amplifier can be switched to the different working
conditions by DIP-switches. The sensitivity of the
device can be switched to 4 basic transmit levels
using the same method. Also, the transmitter power
can be increased to optimize object recognition.
A control unit, which can be activated by simply
pressing a button, is used to determine malfunctions
in the transmitter or the receiver. If nothing is
defective, the test function shows the signal quality
by flashing an LED from 1 to 10 times. The flashes
are proportional to the received signal.
Another feature of the amplifier is the test input which
Pantron Instruments GmbH • Postfach 1129 • D-31158 Bad Salzdetfurth • Tel.: 05063/9591-0 • Fax: 05063/959155
enables a PLC to check the system by switching the
transmitter on and off. This allows the user to verify
the transistor output functionality.
An alarm display and output, which shows errors and
the limit of the transmit power and is connectable
with a PLC, enables users to safely work with the
photoelectric amplifier.
