Cycling, self checking parameter sensing systems that continuously cycle such that the user of the monitoring system can determine not only if the vessel being monitored is above or below the desired parameter value, but also whether or not the monitoring system is functional. When the parameter being monitored is pressure, a system pressure chamber is attached to the vessel being monitored, and the pressure in this chamber is cycled to constantly test the function of the system components. The cycle is monitored for any irregularities.
