Vaisala Indigo500 Series Transmitter


The Vaisala Indigo500 series transmitters are host devices for Vaisala Indigo-compatible, stand-alone smart probes. The transmitters offer many additional features to the Indigo probes.

The Indigo520 transmitter can accommodate up to two probes measuring the same or two different parameters simultaneously. The Indigo510 supports one probe only. When it’s time for calibration, simply remove the probe, replace it with a new one, and send the removed probe for calibration without interrupting your process and reducing downtime. Both the transmitters are available with touchscreen displays made of chemically strengthened (IK08) glass for local data visualization. The transmitters also extend the options for connectivity, supply voltage and wiring, compared to using just an Indigo-compatible probe. Rugged IP66- and NEMA4-rated metal enclosures ensure reliable performance even in the harshest conditions.
