Sensor modules for pneumatic detection of cooling system failures are a low cost monitoring solution for your stand alone cooling system and can be interfaced into any low pressure plenum application.
Need a cost effective solution to monitor cooling air for your equipment? Amphenol CIT has developed an easy to integrate module that incorporates a high sensitivity pneumatic sensor and aircraft grade relay into a single package. This provides a clear signal if the cooling system fails completely or becomes substantially degraded by fan bearing wear or obstructions. Vacuum or over pressure versions with AC or DC relays are available to allow flexibility for your specific application. The pneumatic low pressure flow sensors are ideally used in MRO and VIP installations.
