Thermal Reed Sensors for Sensing Temperature on Boats

Reed Switch based thermal cut-outs are useful in a wide range of applications, either to take certain action like switching on a cooling circuits or to trigger alarms. Due to their sharp cut in, cut out bandwidth and high reliability, thermal reed switches find applications in place of bimetallic strips, thermistors and thermostats for over-heat protection or precise temperature switching. The cut-in temperature is differentiated from the cut-out temperature by an abrupt and huge change in the resistance of the reed switch Contact Resistance of a few milli-ohms to an open circuit resistance of a few mega-ohms. Thermal reed sensors are used on boats to sense engine temperature and give an indication on the instrument panel. Thermal reed sensors can also be used in a variety of applications on boats to monitor oil temperature, coolant temperature etc.
