Hydrogen gas transmitter H₂-Trans

electrochemicalfuel cellwith display

Description
The H₂-Trans is an industrial hydrogen analyzer designed for accurate measurement at trace (ppm) and percent levels. The instrument offers a simple display and one-point calibration for fast commissioning. Optional ATEX certification: Ex ia IIC T4.

Overview

• Measured parameters: Hydrogen (% and ppm)
• Detection method: electrochemical fuel cell
• Measuring ranges: user-selectable; 0–10,000 ppm and 0–100 % (user ranges between 100 ppm and 10 %)
• Accuracy: ±2 % FSD
• Response time T90: up to 45 s (0–1 %)
• Output: 4–20 mA, 2-wire
• Supply voltage: 10–35 V

Detailed description
The unit supports one user-defined measuring range within the available span. It is built for continuous industrial use with a compact enclosure suited to on-site monitoring and integration into process control systems.

Sensor
The H₂-Trans uses a dedicated fuel cell sensor optimised for hydrogen detection. The sensor provides the sensitivity and lifetime expected for industrial monitoring tasks.

Calibration
Trace-range calibration must be performed with a calibration gas at the chosen concentration inside the measuring range. For percent-range measurements, calibration can be performed using ambient air.
