Windows compatible configuration software for Tracker 250 series melt pressure panel indicators
Data Track designed the Tracker 250 digital panel meters specifically for use with Melt Pressure Transducers. Data Track's "Fast Cal" feature provides a fast and simple method of calibrating a panel meter, using the melt pressure transducer's internal calibration resistor. Re-calibration can be undertaken whenever the melt pressure transducer is at ambient pressure (i.e. has no pressure applied to it). Should the melt pressure transducer be faulty, or incorrectly wired, it will be indicated to you during the calibration procedure.
Both the Tracker 253 and 254 panel meters have a 5-digit display and transducer supply as well as many advanced software features. In addition, both panel meters are fitted with an analogue output and an RS422/485 2 or 4-wire communications interface to allow connection to data loggers, chart recorders, PLCs and computers.
The Tracker 254 panel meter also has 2 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 enables you to check the transducer wiring and calibration.
