Protection against icing is vital to prolonging the life and efficiency of gas turbines. Applying the cooled-mirror measurement principle, the Optidew hygrometer (photo) delivers a repeatable, drift-free dew point or relative humidity measurement. The robust design of the Optidew for anti-icing systems is capable of withstanding the moist demanding conditions. When compared with traditional polymer RH probe, the Optidew Anti-icing version offers far better accuracy and stability, says the firm. The unit has a dynamic measuring range from – 50 to 90°C dew point over a temperature range of – 10 to 90°C, and provides two 4–20-mA output signals. — Michell Instruments, Ely, Cambridgeshire, U.K.
