Datasheet Contact Us Moisture, Hydrogen and Temperature Transmitter MHT410 Robust online key gas monitor for power transformers Compatible with all insulation liquids, including silicon oil. Secure your power transmission and distribution. The MHT410 helps prevent power outages and detect possible faults before they escalate. The end-result? Lower total cost of ownership and more secure operation. The MHT410 works in-situ, measuring directly from your transformer insulation liquid. Your gain? Reliable hydrogen trend reading as well as fast moisture data. Continuous monitoring done right Continuously monitoring hydrogen and moisture levels is the first step in extending your transformers’ operational life — and implementing predictive maintenance practices. And when you pair the MHT410 with our robust Indigo520 transmitters giving you a readout both over a sleek WebUI, and the industrial-grade local graphical display — as well as powering the MHT410. 5-year warranty as standard The MHT410 is robust to the extreme. It’s why we are proud to offer it with a 5-year warranty as standard. So you can rely on it to keep going in the harshest of conditions. + Show more Key Benefits Measure in-situ The MHT410 measures directly from all transformer insulation liquids — including silicon oil. No pumps or membranes are needed. Measure in real-time Get reliable hydrogen trend and moisture data in-real time. Get graphical with the Indigo520 Couple your MHT410 with an Indigo520 transmitter and you can monitor your transformer right from a laptop, or the local graphical display to see data trends on site. The Indigo520 can also power the MHT410 with a single-wire solution. Robust design, easy installation. The MHT410’s is made to stand up to the harshest conditions: isolated inputs and outputs, EMC tolerant, and IP66 metal housing. Supplied with standard DNP3.0 and MODBUS RTU communication protocols, it makes deployment within existing communications and SCADA networks easy. The MHT410 even includes three analog outputs for your SCADA interface. Continuous monitoring gives full visibility “It is completely different to follow the situation continuously than to take samples every now and then. After all, electricity networks can have quite exceptional switching situations – a transformer can have very high momentary loads and at other times be used only lightly.” – Operations Manager at Nivos Oy Watch the video Moisture, Hydrogen and Temperature Transmitter MHT410 installation video Downloads Datasheet MHT410 Moisture, Hydrogen and Temperature Transmitter Download Manual: MHT410 User Guide Manual: MHT410 Quick Guide Order Form: MHT410 Order Form (338.12 KB) Technical Note: Activating DNP Protocol for DNP3 (197.22 KB) Customer case: Reference measurement in Vantaan Energy Electricity Networks Ltd. transformer (121.01 KB) Technology Description: DOC238320 DNP3 profile Customer case: TVO Nuclear Power Plant Monitors Transformer Condition Real-Time (139.06 KB) Datasheet: Vaisala HUMICAP® Humidity Sensors (286.61 KB) All downloads Product Resources Keeping the lights on with continuous condition monitoring Read more Optimus™ DGA Monitor OPT100 Read more Two new technical brochures from the CIGRE working group on DGA Read more Customer Stories Customer case Vaisala MHT410 Moisture, Hydrogen and Temperature Transmitter for online transformer condition monitoring Reference customer Use MHT410 as key part of long-term maintenance strategy "With Vaisala's MHT410 transmitter we have an altogether more...
