Description

Precision Duct Mounted Humidity Transmitter with Integrated Chilled Mirror Sensor

The model E4-1111H-GE dew point transmitter was derived from time proven chilled mirror technology, which is widely used for precision humidity measurement in metrology and standards labs worldwide. 

This configuration was developed to measure and control water vapor injection into the intake of gas and liquid fueled power turbines, however the design is applicable to many applications where accurate and repeatable humidity measurement is required. This technology was chosen because power turbines require the precise metering water vapor injection is the combustion chamber to reduce pollutant emissions. Water vapor is also added to the intake of the turbine to increase the mass flow which in turn increases compression and electrical power output. The Model E4-1111H-GE is a laboratory grade chilled mirror hygrometer, designed to meet the requirements of industrial applications.

The transmitter is suitable for operation in a wide range of environmental conditions, including outdoor air. The sensor fully recovers from condensation and exhibits negligible long-term drift. The electronic components used are of the highest industrial quality. Each unit is calibrated to NIST traceable reference standards and the E4-1111H-GE is suitable for use as a dew point transfer standard. General Eastern’s manufacturing and quality system certified to ISO- 9001 standards.
