Vaisala Indigo 300 Series Transmitter

Vaisala Indigo 300 Transmitters is designed to work with Vaisala’s range of Indigo probes.  It comes in a corrosion resistant, robust housing with numerical and graphical display.  This allows local data visualisation and outputs data via analogue signals to your PLC or DCS SCADA system.

Vaisala Indigo 300 has an IP65-rated enclosure manufactured from EN AW-6082.  This is suitable for harsh conditions.  Various mounting options allow for wall mount or DIN rail installations as well as providing the option for wiring through the back of the device to avoid trailing wires. The device uses Vaisala Indigo compatible probes which can be interchangeable to allow versatile measurements in varying applications.  Vaisala Indigo 300 is the middle-of-the-range offering from Vaisala’s Indigo family.  For a lower cost, plastic housing suitable for many pharmaceutical type applications consider Vaisala Indigo Series 200 Transmitters or for dual inputs and relay outputs consider the Vaisala Indigo 500 Series Transmitter.

Vaisala Indigo 300 has a removable front part (display) which allows the mounted part and electrical connections to stay on the wall.  The display can then be removed and used upon a separate body for maintenance work.
