A custom segment that includes softkey prompts which are included as icons in the display. A number of keys are associated with the display. Several functions are assigned to the same key. The prompts that must be displayed for each function so that the operator or user of the device in which the display is used could easily operate the keys to obtain those functions were identified at the start of the device design effort. The prompts were assigned to the keys in a logical manner so that in each state of each operating mode of the device an easy to understand set of prompts appear on the display.

Method and apparatus for providing a softkey prompted user interface

Process control instrument

An electrochemical sensor wherein an ion impermeable plug is interposed between the adjacent faces of the large plugs that are used in the salt bridge. The salt bridge also includes a solid cylindrical plug that passes through the ion impermeable plug to thereby interconnect the adjacent large plugs. The large plugs have a central bore for receiving the glass sense electrode. The impermeable plug has protrusions to provide a better seal between the impermeable plug and the glass sense electrode and the impermeable plug and the housing in which the salt bridge is inserted. In addition, the sensor may also include a rigid liner between the large plugs and the glass sense electrode to act as a barrier to prevent damage to this sense electrode during and after impregnation.

Electrochemical sensor

An electrochemical sensor wherein the salt bridge is a unitary plug of semipermeable material which is saturated with an electrolyte. The plug has a spiral cut from its outer surface to the central bore of the plug. The spiral has at least one complete turn and starts at or near one end of the plug and stops at or near the other end of the plug. A layer of impermeable material is deposited in the plug to thereby form an ion impermeable spiral barrier.
