Maximum control over machines – with iST's moisture-in-oil sensor
Oil is much more than just a lubricant – it is the lifeblood of modern industrial plants. It cools, lubricates, insulates, and transmits power. But how healthy is this “blood” really?
The answer is provided by iST's Moisture-in-Oil Sensor – a compact, digital RH/T module that accurately and continuously monitors the water content in oils and fuels.
Why is this important?
Over time, every lubricant ages: additives break down, contaminants creep in, and the oil's ability to absorb water decreases. This can lead to costly breakdowns and unplanned downtime. The sensor does not simply measure the absolute water content – it measures the relative saturation level in % RH or water activity aw in %. This means you get a direct picture of the current oil quality and can react in good time.
Typical areas of application
The sensor is used wherever machines need to run reliably:
• Marine engines and gearboxes
• Commercial vehicles and rail vehicles
• Wind turbines and generators
• Drilling and paper machines
• Mobile oil filtration units
Technology that impresses – compact, robust, and ready for use
The iST Moisture-in-Oil Sensor has everything modern industry needs:
• Strong stainless steel housing with M14 x 1.5 mm thread – made for harsh environments and tough applications.
• Digital I2C interface – for seamless integration into existing systems, without any effort.
• Temperature compensated and calibrated – unpack, connect, start measuring.
• Test board with 0–10 V analog output – ideal for quick evaluations and initial tests.
• Customized solutions – from assembly to calibration, tailored to your application.
With this sensor, you can rely on reliable technology that adapts flexibly to your requirements and always delivers precise results. Download the white paper for more information.
Technical highlights:
• Measuring ranges: 0–100% RH, -40 to +120 °C
• Reproducibility: ±0.2% RH, ±0.1 °C
• Accuracy: ±3 % RH, ±0.2 °C
Get started right away – with the evaluation kit for the moisture-in-oil sensor
For anyone who wants to test iST's new moisture-in-oil sensor and integrate it into their application, there is a suitable evaluation kit – a practical complete solution for initial measurements and system tests.
The kit contains:
• A mounted and factory-calibrated HYT271 MK33 module that reliably measures relative humidity (water activity aw) and temperature.
• A test board with digital (I2C) and analog (0–10 V) outputs that is particularly easy to use thanks to the user-friendly probe assembly.
• A micro-USB interface for direct connection to a PC – ideal for quick evaluations.
• Compatibility with the Arduino IDE – for developers and technicians who want to work flexibly and efficiently.
Whether for laboratory experiments, prototypes, or initial application tests, the evaluation kit offers everything you need to experience the sensor in action and plan its integration into your systems.
