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 5-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.
