| | | The Vaisala HUMICAP' Moisture and Temperature Transmitter Series for Oil MMT330 enables fast and reliable detection of moisture in oil. The MMT330 can be used in on-line moisture monitoring and as a control device, allowing separators and oil driers to be started only when needed. Proper monitoring saves both oil and the environment. With the MMT330 it is easy and economical to monitor the effects of moisture in oil. Reliable Vaisala HUMICAP® technology he MMT330 incorporates the latest generation of the Vaisala HUMICAP' Sensor, which is the result of ten years of field experience. It was developed for demanding moisture measurement in liquid hydrocarbons, he sensor's excellent chemical tolerance provides accurate and reliable measurement over a wide measurement range. For diverse applications and demanding conditions Because of the variety of probes, the transmitter can be used in lubrication systems, hydraulic systems, and transformers. 72 | | programmed to the transmitter if the water solubility of the oil is known. Graphical measurement trend and historical display he MMT330 can be ordered with a large numerical and graphical display with a multilingual menu. It allows the user to monitor operational data, measurement trends and up to 1-year measurement history. he optional data logger with real-time clock makes it possible to generate over four years of measured history, and zoom in on any desired time or time frame. Versatile outputs and easy installation he MMT330 provides up to three analog outputs. Galvanic isolation of supply power and analog outputs is also available. For serial interface the USB connection, RS232 and RS485 can be used. In addition, alarm relay option is available. he MMT330 has several options for transmitter mounting. Professional transmitters are delivered pre-configured with all settings installation ready. | | |
| | | The display shows measurement trends, real time data and history Indicates the margin to water saturation he MMT330 measures moisture in oil in terms of the water activity (a ) and temperature (T). Water activity indicates directly whether there is a risk of free water formation. he measurement is also independent of oil type and age. Water content as ppm conversion In addition to water activity, the MMT330 can output ppm, the average mass concentration of water in oil. Vaisalahas this conversion readily availabe for mineral transformer oil. For other oils, the oil specific conversion coefficients can be | | |
