According to one aspect, a digital display unit includes a microcontroller to process digital information received from one or more sensors, a display, and a switch in electrical communication with the microcontroller so that the microcontroller displays an output on the display that is specific to a type of sensor. The type of sensor may be selected from a position sensor, a pressure sensor, and a stroke counter. The digital display unit may be part of a choke control panel. The microcontroller and the display may be disposed in an enclosure, and an electrical power source may be disposed in the enclosure to supply electrical power to the microcontroller and the one or more sensors. A digital hydraulic choke position sensor assembly and a digital pressure sensor assembly are also described, one or both of which may be used in a system for drilling an oil or gas well.
