Abstract
A function monitor (10) broadly comprises a detector (14) to sense a condition, a transmitter (18) to monitor the detector (14), and a base unit (20) to receive a status signal from the transmitter (18) indicative of the detector's status. The detector (14) may comprise a pressure switch, a position switch, a level switch, a temperature switch, and/or virtually any device that may be used to electrically monitor the condition. The transmitter (18) preferably receives power through a wireless connection to the base unit (20). The base unit (20) preferably receives the status signal from the pallet transmitter (18) over the wireless connection and actuates a output (30) according to the status signal. The output (30) that may be used to warn an operator of the condition, or take other necessary actions, such as preventing a pump from running.
