We produce bespoke Laboratory gas alarm panels which will monitor both cylinder and bulk storage. Typically, each gas has two indicators displaying the pressure status either NORMAL or LOW PRESSURE.
Pressure is usually detected by a contact pressure gauge or pressure switch.
In the event of low pressure occurring an audible and visual alarm is triggered.
Where flammable gases are monitored the pressure device is protected by a galvanic isolating relay which ensures compliance with the ATEX requirements.
