The model tracker 260 series of digital panel indicators are designed specifically for use with LVDT transducers. Data Tracks “Fast-Cal” feature provides a fast and simple method of calibrating an indicator to the transducer at any two stroke positions. The Tracker 260 is configured for the correct transducer excitation voltage and frequency as recommended by the sensor manufacturer. As LVDT transducers can only be calibrated when in situ, the sensor is set to the mechanical “low” (zero) and then the “high” (span) positions when prompted by the Tracker 260. The measured LVDT signals values are then stored, with their relevant display values, as the calibration parameters. The Tracker 260 can also automatically set the correct input gain to suit the LVDT transducers output. The displayed values can be in millimetres, inches or any other measurement units.
The Tracker 260 series of LVDT indicators have a five digit display, transducer excitation supply and many software features including max/min memory and maths functions. All models are fitted with two analogue outputs. A high speed analogue output for monitoring fast changes of sensor movement as well as a separate, electrically isolated, scaleable analogue output. The serial RS 422/485 communications interface allows connection to data loggers, PLCs and computers. Two logic inputs are provided to allow remote control of user selectable functions. In addition, two of the front panel push buttons can be user defined to allow fast access to pre-programmed functions. The specification of the three models are identical except that the Tracker 264 has two alarm relays, and the Tracker 265 has four TTL alarm outputs.
