Fixed Gas Detection Systems Compact solutions offering remote calibration capability

Controller Series GMA22Compact solutions offering remote calibration capability The GMA22 controller is available either as GMA22-MW or as GMA22-MS, which differ only in the type of internal relays. They thus offer maximum versatility for small gas detection solutions. This applies equally to the gases to be detected, as well as to the transmitter selection and the possible safety concepts. The GMA22-MW and GMA22-MS differ in their configuration of relays and the associated possibilities in applications. Controller for up to 4 measuring points The compact units for wall mounting optionally monitor...

Fixed Gas Detection Systems - GMA22 m Simple stand-alone solutions have their justification, but also two significant disadvantages: » In the event of an alarm, someone has to approach the hazardous area to read or operate the device » The alert is only given at the place of installation and the information is not forwarded A GMA22 enables cost-effective, spatial separation of the transmitter and controller, thus increasing safety. This applies equally to short distances - the controller is then mounted next to the door outside the room to be monitored, for example - and to remote monitoring...
