A sensor head/brew cup with liquid level sensor probes which rotate down into the server to avoid damage to the probes by the server. The sensor head/brew cup moves as a unit, thereby eliminating any gap between the brew cup and the sensor head through which the brewed liquid must pour, thereby preventing spillage. The moveable sensor head/brew allows beverage brewing devices to use servers of various heights. Raising the sensor head/brew cup causes the level sensor probes to rotate upward out of the server, thereby protecting the probes from impact by the server when it is removed from the brewing device. When the level sensor probes are in the upward position they touch electrical contacts completing a self-test circuit confirming electrical continuity through the level sensor probes. |
