What is a tunable diode laser (TDL) transmitter?

A TDL transmitter is the component that communicates an analyzer's readings into displayed measurements and transfers the data to the process control system. METTLER TOLEDO offers two options for transmitters for the GPro 500 tumable diode laser gas analyzer.  

M400 Type 3: This is an external transmitter that provides a local display for your gas analyzer.

Built-in Simple Transmitter: On the SIL version of the GPro 500 there is a built-in transmitter that has 2 analog (4-20mA) signal outputs that are loop powered.
