GPro 500 Transmitter | TDL Transmitter
Process Transmitter for Tunable Diode Laser Analyzers
A tunable diode laser transmitter is a process transmitter designed for use with the GPro 500 TDL gas analyzer for the continuous monitoring of process gases. Select models of METTLER TOLEDO process transmitters can integrate directly with the GPro 500 gas analyzer to provide an easy-to-use interface for process gas measurements of oxygen, CO, CO2, HCl, H2S, CH4, NH3 and water vapor. The GPro 500 transmitter gives the user the convenience of a local display, multiple inputs/outputs and alarms.
Convenience for Process Control
The primary GPro 500 transmitter is the M400 Type 3. This TDL transmitter allows you to have a local display, multiple inputs/outputs and alarms.
Durable Transmitter for Harsh Environments
Designed with a hybrid of touchscreen and soft key interfaces, the METTLER TOLEDO M400 Type 3 TDL transmitter ensures solid operation in any environment without sacrificing convenience or safety.
Easy Integration of TDL Analyzer Data
The M400 Type 3 transmitter offers the HART communication protocol, providing easy integration of gas analyzer data into process control systems.
Fast and Intuitive Navigation
The M400 Type 3 GPro 500 transmitter features a user-friendly touchscreen interface that simplifies day-to-day operation through fast and intuitive navigation.
Suitable for Process Environments
This 4-wire TDL transmitter is ATEX/FM approved for Zone/Division 2 areas. It is suitable for indoor or outdoor use and can be powered by AC or DC.
SIL Compatible Solution Built-In
If your site requires a SIL version of the GPro 500, this does not include an external transmitter. There is a simple transmitter built into the SIL version of the GPro 500.
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.
