The Watchdog low gas pressure alarm by Afriso-Euro-Index can be used with an optional pressure gauge with contacts to monitor and display the pressure in gas-filled containers so that alarms can be generated if the container runs low on gas. A pressure gauge with contacts adapted to the application generates an alarm at the alarm unit via a switching contact if the pressure falls below a threshold (can be set at the pressure gauge to a value 5-95% of the range. An alarm is also triggered in the case of a cable break. The alarm unit is supplied with AC 230V. The low gas pressure alarm features an alarm and an operation lamp, a reset and a test button as well as a relay for supplying the signal to additional alarm devices or to event reporting systems. In the case of an alarm, notifications can be send via e-mail, SMS or telephone. The device may not be operated in hazardous areas (EX zones); however, as a result of the intrinsically safe control circuit, the connected pressure gauge with contacts is approved for EX zones 1 and 2.
