Johnson Controls T-5500-1051 Pneumatic Temperature Indicator 50°F-100°F 3-1/2"

The Johnson Controls T-5500-1051 Pneumatic Temperature Indicator is a pneumatic pressure-to-temperature converter useful in measuring temperatures in air conditioning systems. This device consists of a 3-1/2” analog dial display with a scale of 50°F to 100 °F to enhance the accuracy of the equipment for improved reading. As it works pneumatically and signals temperature changes by switching air pressure, it can be applied to different HVAC systems. A pneumatic temperature sensor is hooked for it to operate and relay temperature information to the indicator. It is then displayed on the analog dial and thus allows for easy and fast monitoring of the temperature.
