The digital display units in the HDA 5500 series are micro processor controlled and are designed for control panel mounting.
The Digga Electronic Display Gauge Kit displays the differential pressure or usable hydraulic pressure. This pressure displayed on the digital screen allows the user to cross reference the displayed pressure (units displayed in bar) with the torque chart supplied to determine the theoretical torque generated by the planetary drive unit.
Note: This kit can only operate on a supply voltage of 12 -32 V DC.
Features
- Digital display of analogue signals
- Clear 4-digit 7-segment LED display
- Up to 3 analogue inputs ( 4.. 20mA or 0 .. 5 V)
