Working together with temperature measurement specialists, Pros by Ditel, Tides Marine has developed a temperature alarm system to work in conjunction with the Tides SureSeals running on commercial and pleasure craft with single- or twin-engine installations.

The SMART SEAL is designed to monitor SureSeal head temperature using a solid state sensor, electronic control module and a remote alarm card or warning siren.

Any increase in the normal operating temperature of the shaft seal will trigger an audible and visual alarm. This alarm will notify the owner and crew that an immediate inspection of the SureSeal is required to prevent damage to the SureSeal.

The control module accepts a 12V or 24V DC power supply and has a self-diagnostic feature on power-up that indicates the system is functioning properly.
