10 FLIGHT 16 MAY 1952 CONTROLS as HUMIDITY CONTROLS The provision of an artificial atmosphere within the pressure hull of the modern aircraft brought with it the problem of controlling the humidity of the air supply, and many aircraft manufacturers turned to us for an answer. An extensive development programme has led us to our present humidistats, which can control to within plus or minus \\°/0 R.H. and are stable over a wide range, even when high dry bulb temperatures occur together with high values of R.H. Many and varied are the installations we have provided; some in corporating a water separator control and some an R.H. indication, sensing from an identical pick-off to the controller. We can, without doubt, assist in your problems of humidity regulation. AUTOMATIC CONTROLS TEDDINGTON CONTROLS LTD., CEFN COED, MERTHYR TYDFIL, SOUTH WALES.
