Moisture analyser and probe from GE

This single channel analyser is designed for accurate, real time and reliable operation with the company’s field-proven M series probes or with the new, iQ probe which can detect parts per billion changes in moisture concentration.

The analyser is intended for applications where moisture content impacts the product quality or performance or the process efficiency.

Typically, this can include industrial and furnace gases, cooling gases and air drying in sectors such as power generation, metal manufacture, aerospace, pharmaceuticals and general engineering.

“Moisture content is an unwanted property in many situations,” said GE’s product manager Nigel Sparges.

“The microprocessor-based dew.IQ accurately tracks fast-changing process conditions and displays the moisture content as dew/frost temperature or as parts per million by volume (ppmv). Two alarm relays provide indication of when high and low limits are exceeded.”

The compact dew.IQ features a real time clock and data logging to allow performance monitoring and enhanced trouble-shooting.

It can be used with a choice of two rugged and accurate, aluminium oxide sensors, both of which offer exceptional dynamic range and speed of response with calibration traceable to national standards.

The electronics are self-calibrating, ensuring long-term stability. Sensor calibration data is stored in a non-volatile memory so data entry to the connected dew.IQ is automatic. 

The IQ.probe can be located precisely at the process to be measured. It can withstand process temperatures down to -110°C (-166°F) and up to 70°C (158°F) and process pressures from vacuum up to 5000 psig (345 bar).

Installation is simple, with connection to the analyser by means of an inexpensive, unshielded twisted pair cable, which can be up to 3000 feet (0.9 km) in length.

The dew.IQ moisture analyser and its associated probes are supported globally by GE’s experienced applications engineers, technical support teams and calibration centres.
