MOISTURE METER DP-101

  • MOISTURE METER DP-101


    DP-101 is a Portable Moisture & Temperature meter or a sensor that provides an excellent reliable, economical and Time saving solution for measurement of moisture n the field.

    It measures Moisture-in-oil in terms of the Water Activity (aw) and Temperature. The same gets converted into PPM units as in Transformer applications, PPM-unit is traditionally used.

Description

The MOISTURE SENSOR is of solid polymer structure and is, fast, accurate and reliable water and temperature transducer’s designed for industrial, transformers and locomotive applications where a reliable and accurate measurement of water content is highly required. Its fast response time combined with Reliable and rugged structure make it even suitable for fixed in situ mounting in fluids under pressure

Dissolved water is a critical data for Oil system management as water consumes oil additives that can result in severe mechanical damages due to degradation of lubricant properties.

In a comprehensive transformer maintenance program, determination of the moisture content and temperature of the oils is an essential part. Excessive moisture contents causes accelerated ageing of the insulation materials and reduce their dielectric strength. In extreme cases this can result in arcing and short circuits within the windings. Accurate moisture analysis can also warn about Leaks in system as water is absorbed from the surrounding air.
