Vaisala MMT330 Oil Moisture and Temperature Transmitter
I. Product Overview
The Vaisala MMT330 is an oil moisture and temperature transmitter series from Vaisala (Finland), using HUMICAP® sensor technology. This series is used for measuring moisture content and temperature in transformer oil, hydraulic oil and lubricating oil.
The MMT330 series has a temperature measuring range of -40 ~ +180 °C, accuracy ±0.2 °C (at 20°C). Moisture measurement is based on HUMICAP capacitive sensor, measuring water activity and ppm in oil.
The MMT330 series includes multiple sub-models: MMT332 (high-pressure installation), MMT337 (small space threaded connection), MMT338 (pipe mounting), suitable for different installation scenarios.
