Abstract: A pump includes a pump head and a motor assembly including a motor. The motor engages the pump head and actuates the pump head. The pump includes a hand actuatable quick disconnect assembly coupling the pump head to the motor assembly without the need for tools. A pump monitoring system acquires data and information to detect problems and provide information for pump maintenance.

Abstract: A sensor cable for measuring moisture inside a grain bin includes a moisture sensor connected to a moisture sensor wire and a pair of holes in the sensor cable. The holes are associated with the moisture sensor to enable the moisture sensor to sense moisture via both of the holes. In one implementation, a moisture sensor is connected to a 3-wire interface having separate power and data wires, thereby increasing the read speed. In one implementation, the moisture sensor is encapsulated within a node that is flush with the sensor cable to minimize load on the sensor cable from the surrounding grain.
