DI2 Process Indicator
The DI2 Loop Powered process Indicator is a self powered 4-20mA input panel mounting process indicator which is housed in a 48 x 96mm impact resistant aluminium enclosure with weatherproof front. The instrument incorporates a 3.5 digit 12.5mm high LCD display with a wide viewing angle. It is user programmable in engineering units.
CALIBRATION NOTE
- Accepts 4-20mA or 10-50mA input
- User programmable in engineering units
- Loop powered
- Low cost – High Performance
- Positive or negative signal slope selection
- DI2 is in a panel mount enclosure
- Applications include the display of flow, level and pressure
- Australian design and manufacture
The DI2 instruments have been designed to accept an input signal of 4-20mA or 10-50mA and be powered from that signal. The input measurement is shown on a 12.5mm digit height 3.5 digit liquid crystal display (LCD).
They are user programmable in percent or engineering units for such process variables as flow, level, pressure and temperature.
The instruments have been designed to reject electrical interference that normally abounds in industrial environments.
The DI2 is supplied in a 48 x 96mm panel mount enclosure.
