PANTRONISM-1230/24VDC

ISM-1230

1-channel automatic amplifier for optical dust and turbidity measurement. The ISM-1230 is a one-channel amplifier for optical dust and turbidity measurement. Using modulated infrared light, it automatically adjusts transmit power so the receiver maintains a constant signal level while a 0 ... 10 V analog output tracks actual process attenuation.

Key Features

Special amplifier for optical dust and turbidity measurement.
Automatic transmit-power regulation compensates for slow sensor contamination.
Basic transmit level selectable low or high.
Analog output proportional to attenuation / turbidity conditions.
Alarm output for power limit and teach input for setup.
DIN-rail package with floating switching output.

Best Fit Applications

Dust level monitoring in process ducts and equipment.
Optical turbidity measurement where media change over time.
Installations where sensor contamination changes slowly but process turbidity changes quickly.
Long-range opposed-mode monitoring with infrared sensors.

Device Notes

Analog output depends on sensor spacing, alignment, contamination, and actual medium turbidity.
With fixed sensor mounting, fast changes at the output mainly represent actual turbidity.
