INTRODUCTION
The SafeGuard is a configurable gas monitoring instrument which can accommodate up to 7 sensors.
There are 2 models in the range, the Safeguard-A with an integral pump for monitoring atmospheric
contaminants and the Safeguard-C with integral pressure regulator for monitoring compressed-air
supplied between 1.5 and 10 barg.
The unit has a volt free contact to allow it to be used for a range of scenarios such as sounding an
external alarm or shutting down equipment.
The instrument’s alarm settings and its datalog file can be configured by the user over a wireless
interface. The Safeguard has been designed for operation in challenging ambient light conditions, the
large 3.5” LCD display shows live sensor readings. If any of these exceed the configurable alarms levels
they automatically change colour to indicate which of them are now in alarm. At the same time a 360°
edge light will show users who cannot directly see the screen that the unit is in alarm.
The instrument can be powered directly from a 110/230V mains supply via an adaptor (or 12/24V DC)
and also incorporates rechargeable batteries as a back-up providing up to 8 hours of run time.
Depending on the number of sensors fitted the user can display the sensor readings in a variety of
formats.
The SafeGuard can be configured using a local WiFi connection which is available from a smart
phone/tablet device; this allows alarm readings and datalogging interval to be set. The datalog can also
be downloaded as a CSV file and includes the minimum, maximum and average sensor reading during
the user selected datalogging interval.
Future options includes the ability for multiple units to have mesh connectivity, so that if any
SafeGuard goes into alarm it automatically triggers every other instrument in the group. With fully
featured cloud based data logging over WiFi or a GSM connection and a remote alarm beacon.
