The CCL2Ba Casing Collar Locator (CCL) Beeper printed circuit board (PCB) is an audible and visual indicator designed to work with any CCL meter surface amplifier (it works very nicely with our CCLM1a CCL Meter Surface Amplifier). It is used primarily with non-amplified "shooting" CCLs, but can also be configured to work with amplified "logging" CCLs. (See our Casing Collar Locator (CCL) pages for more general information.) This improved design incorporates a better current limiting scheme for maximum safety.
The audible tone is switch selectable for High, Low and Off and the annunciator is also equipped with a mechanical volume control. The optional high brightness LED visual indicator can also be equipped with an on and off switch. The sensitivity (threshold that produces a beep) can be set by trimpot on the board, or a front panel control can be provided. The duration (length of beep) can be set by trimpot on the board, or a front panel control can be provided. Paul Knight's meter protection circuit to prolong the life of the meter movement is also incorporated if the CCL meter is not already so equipped; said feature can be ignored, set to full time operation, or can be switch selectable. Selectable components are turret terminal mounted to ease selection or change once the board is installed.
The CCL2Ba CCL Beeper PCB can be used for new installations or to repair and improve existing equipment. The board can be installed directly on the back of standard meters, or it can be chassis mounted. It uses readily obtainable components, which parts will continue to be available for many years to come, and it uses convenient turret terminals for wiring connections. Also see Application Note CCL Beeper for detailed application and installation information. Due to time constraints on maintaining this website, the PCB illustrated below may not be the most recent revision of the board and / or circuit.
