Series composition and options

The XT series is a product line designed to meet various gas detection and life safety requirements, consisting of Satellite XT, Extraction Module XT, and Pyrolysis Module XT. Modular settings allow users to easily switch from "point of use" detection to extractive detection.

Extraction module XT: an ideal add-on component that allows gas sampling and detection in various environments, such as in-situ pipeline testing and detection in harsh or remote areas. Its main function is to transfer gas samples from monitoring points to sensors.

Pyrolysis module XT: The XT series has been improved to allow for the detection of fluorine-containing gases. Its core component is the pyrolyzer, which can convert gases into inorganic acids.

Sensor Expansion: Available in three lengths: 1 meter, 2 meters, and 3 meters.

Working principle of sensors

Electrochemical sensors are all ampere type, similar to fuel cells. In order to generate current, they lack a component, which is the gas (target gas) that should be detected. The target gas diffuses through the breathable membrane into the sensor, where an electrochemical reaction occurs, producing a low current proportional to the measured gas concentration (usually read in nA/ppm).

The current is amplified into a signal and processed by electronic circuits to display real-time gas concentration. The zero current of electrochemical cells always exists and is monitored and suppressed by electronic devices.

Honeywell Analytical Instruments has created an "intelligent sensor" with a built-in PROM that programs all relevant sensor data (such as sensitivity, target gas, first calibration date, calibration data, zero current, and alarm level) onto the chip. The detector can read this data and automatically adjust the amplification factor.

Sensor self-test

All relevant sensor data is programmed into the PROM inside the electrochemical sensor, and the detector can read this data. Perform an automatic sensor self-test every 24 hours, comparing the electronically activated sensor signal with the stored calibration curve to ensure that the sensor remains within the specifications set during the initial calibration. If the sensor exceeds the specifications, the instrument will indicate that the sensor needs to be checked or replaced.
