Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.

Vaisala Indigo500 series transmitters serve as hosts for standalone smart probes that are compatible with Vaisala Indigo. The transmitter come with extra features compared to the Indigo probes. Vaisala Indigo520 transmitter can handle two probes measuring either the same or different parameters at once, while the Vaisala Indigo510 supports one probe only. When calibration is needed, you can easily swap out the probe without interrupting your process and reducing downtime..

Both transmitters feature touchscreen displays with chemically strengthened (IK08) glass for local data visualization. The transmitters offer expanded connectivity, supply voltage, and wiring options compared to using just an Indigo-compatible probe. The rugged IP66- and NEMA4-rated metal enclosures ensure reliable performance in tough conditions. The Indigo-compatible smart probes include humidity (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point, carbon dioxide probes (GMP251 and GMP252), moisture in oil (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). Additionally, the Vaisala Indigo500 series is compatible with the MHT410 Moisture, Hydrogen, and Temperature Transmitter for power transformer online monitoring.


Key Benefits

Touchscreen Gives Easy Access To Probe Data

Intuitive touchscreen provides local data visualization.

One Probe Measurement Or Two Simultaneous Ones

Vaisala Indigo520 dual-probe support allows simultaneous measurements with two Vaisala Indigo-compatible probes for humidity, temperature, dew point temperature, carbon dioxide, vaporized hydrogen peroxide, and moisture in oil measurements. If you need just one probe, the Indigo510 is an ideal choice.

Rugged Design With Metal Enclosure

A metal enclosure with IP66 and NEMA4 classification makes Indigo500 series suitable even for the harshest conditions. The touchscreen is made of chemically strengthened glass, making it robust even in demanding industrial applications.

Analog & Digital Outputs

Vaisala Indigo520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. Vaisala Indigo510 has 2 analog channels. Any of the output parameters from the connected probes can be assigned to control the analog channels and relays. Digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter’s Ethernet connection provides a web interface and cyber-security that meets the modern standards.

Extended Power Supply Options

Vaisala Indigo500 also extends the power supply options of the Indigo-compatible measurement probes. The power supply option in Indigo510 is 10 … 35 VDC. The Indigo520 has multiple power supply options:
• Protected extra-low voltage (PELV) version: 15 … 35 VDC, 24 VAC ±20%
• Main power version: 100 … 240 VAC 50/60 Hz
• Power over Ethernet (PoE) version: 50 VAC PoE+

Time-Savings & Reduced Downtime With Plug & Play Design

Indigo-compatible probes are simple to attach, making installation quick. You can connect the probes to transmitters using a cable, allowing a distance of up to 30 meters between them. Swapping probes for calibration or maintenance is also easy, thanks to the plug-and-play design, saving time and reducing downtime.
