PROBLEM TO BE SOLVED: To provide an environmental control system and a speed sensor module in the system.SOLUTION: An environmental control system includes an air cycle machine 100 for conditioning an interior space with cooling air, a speed sensor module 105 having a speed sensor 135, and a diffuser assembly 110 having a cylindrical assembly 165. The machine 100 includes a fan 115 coupled to a shaft that rotates about a shaft axis, the fan being located at a distal end of the air cycle machine. A speed sensor senses a rotational speed of the shaft. A module 105 includes an outer portion having a first bore, an intermediate portion having a second bore, and an inner portion. A cylindrical assembly ducts a first portion of the cooling air to an inlet side of the fan and communicates a second portion of the cooling air directly to a discharge side of the fan without passing the inlet side.
