The INFINITY®
The INFU universal meter is ideal for those who want
a single meter to cover a variety of input needs. This meter
can measure a broad spectrum of dc voltage and current ranges,
nine thermocouple types, a variety of RTDs, a multitude of
inputs from pressure transducers, load cells, strain gages
as well as potentiometric inputs. Six full digits make this
meter ideal for demanding process control applications. On-board
excitation is included so you can power virtually any sensor
or transmitter, and four standard setpoints give the flexibility
to control or alarm your system completely. The various setpoints
can be configured as active above or below, latching or non-latching,
as either high deviation, low deviation or band deviation,
as well as numerous other possibilities.
The meter is delivered configured for the input type you choose.
The meter can be easily reconfigured using the front pushbuttons
or via either of the optional serial communications boards.
All options are field installable, so you can easily upgrade
as your needs change.
