Compact Moisture in Oil and Temperature Transmitter
The CST Moisture and Temperature Transmitter for Oil, OMT200 is an excellent economical solution for reliable on-line detection of moisture in oil.
Features/Benefits:
Reliable CST Technology:
The sensor is developed for demanding moisture measurement in liquid hydrocarbons and has been successfully used in oil applications for over a decade. The sensor's excellent chemical tolerance provides accurate and reliable measurement over the measurement range.
Water Activity Measurement:
The CST measures moisture in oil in terms of the water activity (aw) and temperature (T). Water activity directly indicates whether there is a risk of free water formation. The measurement is independent of oil type, age and temperature. The ppm calculation for mineral oil based transformer oil is optional in the OMT300.
