The Johnson Controls T-5502-1134 Thermostat 2-1/2″ 60/85F
The T-5500 Pneumatic Temperature Indicator provides continuous visual indication of temperature measured by a transmitter with a 3 to 15 PSIG (21 to 105 kPa) output range. The gage features a 3-1/2 in. (89 mm) dial size in standard and metric ranges with an accuracy of ±1/2% of full range (see Specifications).
The dull black lacquer finish and black printing contrast with the white dial face for easy readability and attractive appearance. The equivalent metric scale is printed in blue. The clear plastic protective lens screws off for cleaning and easy access to the recalibration screw on the dial face.
The T-5500 indicators can be flush or surface mounted. For flush mounting, “U” clamps are furnished with break-off notches to accommodate panel thicknesses from 1/16 to 3/4 in. (2 to 13 mm).
