Hydrogen Test Bed Facility

Hydrogen Test Bed Facility – Software Development & Commissioning

PLC Software development using GX Works and GT Works for a West Midlands manufacturer’s design concept team. The project was to expose multiple samples of pipe to hydrogen gas at precision test pressures, precision test temperatures for months at a time and data logging of process variables every 20 seconds for remote collection.

Based on Mitsubishi MELSEC L02 series PLC and GOT HMI, digital and analogue signals, PID control, temperature control by pulse width modulation of “slugs” of hot water to the hazardous zone. The GOT HMI was programmed to guide operators in the safe handling of hydrogen gas, Nitrogen purging and automatic controlled replenishment of gases.
