Michell Instruments, which is represented by AMS Instrumentation & Calibration, has a long-standing customer which specialises in evaluating and testing ultra high pressure (UHP) air systems.
Due to the high pressures involved, it’s important that the air is pure and free from contaminants such as compressor oil particulates or water.
Australia's SA Marine uses a desiccant dryer to remove vapour from the air and an online hygrometer from Michell to measure the water dew point at delivery, as part of their portable test set.
The Michell ceramic impedance sensor is able to measure the dew point temperature at line pressure which gives SA Marine complete confidence in its measurements.
It also provides an inspection service for breathing air cylinder-filling apparatus for both naval and commercial customers. In this case, too much moisture would lead to potential bacteria which would pose health problems for users.
Back at their company facilities, SA Marine uses a Michell chilled mirror hygrometer as a high-precision calibration reference on a test rig.
