fga311

 

Economical Solution for Multiple Applications

 

The FGA311 is a low-cost, in situ, flue-gas oxygen transmitter. Its compact transmitter design incorporates the electronics and oxygen probe into one weatherproof or explosion-proof package. This microprocessor-based oxygen transmitter is designed to stay on the job with minimum downtime. The transmitter is ideal for clean-burning applications such as boilers, process heaters and furnaces. It offers an economical solution for multiple installation applications.

Features

  • Microprocessor-based
  • Fail-safe diagnostics
  • RS232 digital and 4mA to 20mA analog outputs
  • Easily serviced
  • Weatherproof and explosion-proof packages available

Applications

An in situ oxygen transmitter for use in:

• Natural gas or oil-fired utility boilers

• Natural gas or oil-fired process heaters 

Specifications

The FGA311 transmitter is economical to own and maintain. Proprietary coatings on the zirconia oxide sensor extend sensor life. Through an innovative design, the sensor can be withdrawn and serviced without removing the analyzer body from the installation point. The FGA311 transmitter has an isolated analog output as well as an RS232 digital interface. It also features fail-safe diagnostics, which include a watchdog timer. It is fully field-serviceable and field-programmable.
