Technical description of the tensometric comparator
Power supply voltage is to be connected to the terminals
marked as 24V and GND. The feeding circuits include a
protection
against
protection and an impulse stabilized supply. These elements
provide an increased resistance of the device in industrial
environment.
The tensometric sensor in the bridge connection is to be
connected through four wires marked as +I and -I for converter
power supply and +U and -U for sensor output voltage.
The resulting value is displayed by means of four-digit
seven-segment display with the height of characters of 14 mm
that is complemented with the measured signal polarity sign.
Measurement takes place in a bipolar range with the maximum
values from –32767 to 32767 bits. The maximum range
displaying is between –9999 and 9999. When exceeding the
displayable range, "nnnn" is shown on the display. When
exceeding the minimum value of the AD converter, "LLLL" is
shown on the display and when exceeding the maximum value
of the AD converter, "HHHH" is shown on the display. It is also
possible to set activation of any of four decimal points in the
parameters.
The device includes two output relays. The first one is
utilized in a function of the comparator – it closes if a signal
exceeds the set closing value and opens if a signal is lower the
set opening value. The other relay is in a fault function. After
turning on the device, the relay closes and opens only in the event
of presence of a fault – exceeding of the ranges of the AD
converter. A switching contact of each relay is available on the
output terminals.
Two logic outputs with the voltage level of 24V are
separated from other circuits of the device in a galvanic way. The
first input (+In1 and –In1 terminals) is intended for device
status blocking. In case of activation of this input, the last
