1. A data logger device for connection to an air pressure supply line to an air motor driving a flexible cleaning lance hose drive apparatus, the device comprising:
a cylindrical housing having a central axis and removably fastenable to a pressurized air supply line to an air motor driving a flexible lance hose drive apparatus via a quick disconnect fitting connector;
a circuit board mounted in the housing parallel to the axis; a pressure transducer mounted on the circuit board in the housing operable to continuously monitor air pressure within the air line in real time; and
a datalogging processor and memory on the circuit board in the housing communicating with the transducer for recording clock time of sensed pressure from the transducer and providing an input to automated lance hose drive control circuitry that initiates automated lance reversal operations upon sensing an obstacle in a tube being cleaned by a cleaning lance driven by the drive apparatus and initiates cleaning fluid pressure dump operations upon sensing an unexpected event.
