CERTIFICATION #92-152 |
The
INFW scale meter is a microprocessor-based indicator/
controller with enhanced features that allow you to easily configure
the unit for virtually any application. It is compatible with
most strain gage sensors such as load cells and pressure transducers.

The INFINITY®
scale meter can be configured, via the five front-panel pushbuttons
and/or the optional serial communications boards, to accept any
of a variety of dc voltage ranges (some ranges plus unipolar or
bipolar are first selected via a jumper located at the top of
the instrument housing) and display them in engineering units.
Standard features include normal or sequential tare, peak or valley
recall, tare limit, and a high resolution A/D converter with digital
scaling and offset. Other features include dual relay or BCD output,
isolated analog output, RS-232 or RS-484 serial communications
options, auto or sequential tare, class selection, and display
of units of measure. Self-diagnostics are performed automatically
on power-up.
These meters provide both software and hardware lockout configurations
which let you define the parameters, from setpoint adjustment
to total reprogramming. Users can scale and offset their input
signal into any engineering units desired. This is accomplished
by the use of an exclusive two or five data point method of scale
and offset for linearization of input signals transmitted from
a sensor. The meter provides a choice of sensor excitations of
1.5 to 11 Vdc or 24 Vdc for sensors such as load cells, strain
gages, and pressure transducers.
