Supplier News

VAISALA’s duct-mounted HMD60/70 and wall-mounted HMW60/70 humidity and temperature transmitters are designed for use in close control air conditioning applications where accurate and stable measurement of humidity and temperature is required.

The transmitters are easy to calibrate on-site without disturbing the measurement. Both true two-wire and three-wires models are available.

Moisture in oil

Vaisala also has available a new transmitter for measuring the amount of moisture in oil.

The HMP228 moisture in oil transmitter now makes it possible to provide on-line, continuous measurements of the moisture levels within oil. This can significantly reduce maintenance costs and prolong machine lifetime.

The main application areas for the HMP228 are for lubrication oils, transformer oils and cooking oils / food industry.

The HMP228 provides the both the temperature and the water activity measurement of an oil. The water activity measurement has a number of advantages over the traditional ppm measurement, as the water activity is independent of the grade of oil, its quality and condition.

For those that prefer ppm measurements, the transmitter is able to produce the ppm output for a range of oils, once the oil specific parameters have been entered into the transmitter.
