Specification

The Tracker 250 series of digital panel indicators
are designed specifically for use with Melt
Pressure Transducers. Data Track's "Fast-Cal"
feature provides a fast and simple method of
calibrating an indicator, using the transducers
internal calibration resistor. Re-calibration can
be undertaken whenever the transducer is at
ambient pressure (i.e. has no pressure applied to
it). Should the transducer be faulty, or incorrectly
wired, this will be indicated during the
calibration procedure. Both the Tracker 253 and 254 have a five digit
display and transducer supply as well as many
advanced software features. In addition, both
models are fitted with an analogue output and an
RS 422 / 485 communications interface to allow
connection to data loggers, chart recorders, PLCs
and computers. The Tracker 254 also has two
alarm relays, both with volt free change over
contacts. The displayed pressure can be in psi,
bar, MPa or any other engineering units. A
special "test" function allows the transducer
wiring and calibration to be checked.
