Oil Moisture Transmitter MMT330 Series

The Vaisala Indigo, Indigo 510, Indigo 520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. The 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

The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends the options for connectivity, supply voltage and wiring, compared to using just a smart probe. It also provides mechanical support when wall-mount probe installation is preferred.​ Rugged IP66- and NEMA4-rated  metal enclosure ensures reliable performance even in the harshest conditions.

The Indigo-compatible smart probes include humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8),  carbon dioxide probes (GMP251 and GMP252), moisture in oil probe (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). The Indigo520 is also compatible with MHT410 Moisture, Hydrogen and Temperature Transmitter for power transformer online monitoring

The 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.

The Vaisala MMT310 series incorporates the latest generation of the Vaisala HUMICAP® Sensor, developed for demanding moisture measurement in liquid hydrocarbons.

The sensor’s excellent chemical tolerance provides accurate and reliable measurement over the wide measurement range.

The MMT310 series can be used in lubrication and hydraulic systems as well as in transformers. It can be used for on-line moisture monitoring and as a control function, allowing separators and oil purifiers to be started only when necessary.

for continuous online measurement​

Vaisala HUMICAP® Moisture in Oil Probe MMP8 enables fast and reliable measurement of moisture in oil. It uses the proven Vaisala HUMICAP® sensor that was developed for demanding moisture measurements in transformer and lubrication oils, hydraulic fluids, and other liquids.

MMP8 measures dissolved moisture in oil in terms of water activity (aw), relative saturation (%RS), and temperature (T). It also calculates ppm concentration for specific oils.

>MMP8 is part of the Indigo family and is compatible with Indigo500 and Indigo200 series transmitters. It can be used with the Vaisala Insight PC software for data visualization, easy probe configuration and self-calibration.

for Vaisala's Smart Humidity, Temperature, Dew Point, Moisture in Oil, CO2 and H2O2 Probes

Vaisala Indigo200 Series host devices are part of Vaisala Indigo product family and intended for Vaisala's intelligent, stand-alone humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8), temperature probe (TMP1), CO2 probes (GMP251 and GMP252), moisture in oil probe MMP8, as well as our vaporized hydrogen peroxide probe series HPP270: including HPP271 to measure hydrogen peroxide vapor (ppm), or the HPP272 to measure hydrogen peroxide vapor (ppm), temperature, and humidity (relative humidity and relative saturation). The HPP272 probe includes other calculated parameters such as dew point and vapor pressure measurements..

Looking for a transmitter with a metal enclosure? See Indigo500 series with dual-probe support and many more additional features.

Typical applications for the Indigo200 include industrial and compressed air drying, life science incubators, hatchers and setters, greenhouses, cold storage & refrigeration, food transportation, CO2 safety, hydraulic and lubrication oil monitoring, demanding HVAC such as animal shelters, swimming pools, parking garages, and facilities using vaporized hydrogen peroxide decontamination.

Vaisala Indigo 200 allows for easy evaluation and visualization of data, also wirelessly. The installation is uncomplicated, which saves time. Watch video on how to install Indigo201 and configure analog outputs. Also the probe types are interchangeable reducing downtime. The enclosure with an IP65 classification is safe for harsh environments and resistant to dust and most chemicals. The smooth surface of the enclosure makes cleaning easy.

The Vaisala HUMICAP Hand-held Moisture Meter for Oil MM70 enables reliable detection of moisture in oil. Among its main attraction are:

Vaisala Indigo300 Transmitter is a host device for displaying measurement values from Vaisala Indigo-compatible probes and/or transmitting them to automation systems through analog signals.
