TENZ2174T
TENSOMETRIC COMPARATOR
1. General description of the tensometric comparator
The tensometric comparator TENZ2174T is a digital
electronic device that converts signals from a tensometric bridge
(sensor) on numerical data that are displayed on a 4-digit LED
display. Measurement of the tensometric signals is performed by
means of the 16-bit AD converter. The measured value is
processed in the control microprocessor in dependence upon two
calibration constants that have been obtained by calibration
measurement.
The comparator includes two output relays, one with
adjustable values for turning on/off and the other one in a function
of a fault relay. Two outputs separated in a galvanic way allow
device blocking when the last measured value remains on the
display and value resetting when the currently measured value is
assigned to zero value. All parameters are stored in the memory
of the device and their adjustment can be performed using four
pushbuttons.
The comparator is powered with direct current voltage of
24V. Control voltage supply is not protected with a fuse. The
comparator is installed in a plastic box intended for installation on
the strip DIN35.
