Abstract
A plurality of probes are electrically connected to a central controller. Each of the probes is capable of providing a hydrocarbon signal, a water signal, and a dry signal to the controller upon sensing these respective environments. The controller includes an alarm transducer, relays, a keyboard, and a liquid crystal display (LCD) connected to a microprocessor and associated memories. A software program stored in memory is utilized by the microprocessor to permit users to individually select alarm conditions for each probe and relay and the latching condition for each relay which conditions are stored in memory. The probes that activate each relay may also be selected and stored. There is an RS232 port connected to the microprocessor circuit via which probe status can be requested by and communicated to a remote terminal. Upon receipt of probe signals corresponding to the selected alarm and latching conditions, the microprocessor activates the alarm and relays as programmed.
