P&ID ID Letters for Methane Sensor & Detector

[jkate]

I'm working on a project that will require a Methane Sensor and a Methane Detector. Both will transmit concentrations to the Main Control Panel and both will trigger alarms. What letters do I use in the instrument bubble for each of these devices?

Thanks

What is the difference between a methane sensor and a methane detector? I'd consider them both to be doing the same thing.

The methane sensor would be AE for analytical element, with CH4 or METHANE outside the bubble, unless it transmits a standard signal, in which case it'd be AT (with the same outside bubble annotation).
