Overview
The SF72 Rail is a cost-effective moisture transmitter designed to continuously monitor the performance of compressed air dryers on railway rolling stock, helping ensure the safety and efficiency of braking and other pneumatic systems. It uses Michell's latest-generation polymer moisture sensor for fast, reliable dew-point readings that let operators act quickly.
Working Principle
A polymer capacitive moisture sensor measures dew point directly in the compressed air line via a G 1/2" BSP process connection, with a heavy-duty M12 electrical connector carrying the signal, giving fast response across a wide dew-point range to suit varied railway operating conditions worldwide.
Applications
Benefits
- Purpose-built rail approvals remove qualification risk for rolling-stock fleets
- Wide dew-point range copes with extreme climates encountered worldwide
- Fast polymer sensor response supports quick operator action on dryer faults
