Vaisala Indigo300 Industrial Transmitter
The Vaisala Indigo300 is a rugged industrial transmitter for one Vaisala Indigo-compatible smart probe, providing local measurement display and up to three configurable analog outputs.
Its corrosion-resistant IP66 metal enclosure, flexible probe mounting and interchangeable probe design make Indigo300 suitable for humidity, temperature, dew point, CO2, moisture in oil and other demanding industrial measurements.
Vaisala Indigo300 Rugged Intermediate Transmitter
The Vaisala Indigo300 is the intermediate model in the Indigo transmitter range. It connects one interchangeable Vaisala smart probe and provides three configurable analog outputs in a corrosion-resistant IP66 metal enclosure.
Indigo300 is particularly suitable when a project needs more rugged construction than Indigo200 but does not require the Ethernet, web interface or dual-probe capabilities of the flagship Indigo500 Series.
Why Choose Indigo300?
- Rugged Intermediate Platform: Industrial metal construction between the standard Indigo200 and flagship Indigo500 families.
- One Interchangeable Probe: Supports a single compatible probe selected for the required measurement.
- Three Analog Outputs: Current or voltage channels can transmit up to three selected parameters.
- Clear Local Display: Numerical and graphical colour display shows up to three parameters; non-display version is also available.
- IP66 Metal Housing: Corrosion-resistant aluminium enclosure for demanding industrial environments.
- Flexible Probe Positioning: Install the probe directly or use a compatible extension cable.
- Service Port: Supports connection to Vaisala Insight PC software or the Indigo80 handheld indicator.
Selecting the Correct Indigo Transmitter
| Transmitter | Position | Connected Probes | Main Outputs | Best Fit |
|---|---|---|---|---|
| Indigo200 | Standard | One | Analog or Modbus RTU model; 2 relays | Normal industrial measurement |
| Indigo300 | Intermediate | One | 3 analog outputs | Rugged metal installation with analog signals |
| Indigo510 | Simplified flagship | One | 2 isolated analog outputs, Ethernet and Modbus TCP | Premium single-probe integration |
| Indigo520 | Full flagship | Two simultaneously | 4 isolated analog outputs, 2 relays, Ethernet and Modbus TCP | Advanced dual-probe systems |
Important: Indigo300 is an analog-focused transmitter. Choose Indigo200/Indigo202 when Modbus RTU and relays are more important than metal construction, or Indigo510/520 when Ethernet and Modbus TCP are required.
