Measuring devices Room gas monitoring devices GasSafetySensor The GasSafetySensor is designed for monitoring the ambient air in rooms with gas-filled equipment for measuring different tracer gases. The Sensor unit detects the lowest concentrations of the gas to which it is adjusted/calibrated and permanently shows the current measured value on the display. There is no radioactive source in any of the DILO Sensors, so no special precautions regarding radioactive hazardous substances are required during operation. The Sensors are also characterised by a fast response time with stable measuring results. Cross-sensitivities of the Sensors to other gases and to air moisture are not known. Naturally existing gas components in the air can be suppressed. For example, when using a CO2 sensor, it can be set in such a way as to hide the natural CO2 content in the air so that only values which are above this natural content are measured. The warning and alarm levels of each Sensor can be freely configured. If the default setting is to be changed this can be done either via the connected GasSafetyMonitor or via a web server.

Advantages & functions ■ operation either as a stand-alone unit or in networks connected to a GasSafety Monitor ■ different acoustic signals to be set on the unit; visual display of errors, warnings and alarms ■ potential-free relays for errors, warnings and alarms ■ high long-term stability ■ Sensors are connected via an RJ45 cable (Ethernet and Power over Ethernet (PoE)) ■ no maintenance and no consumables required ■ analogue output (4...20 mA) ■ message on the expiry of the recommended calibration interval ■ power is supplied separately (24 V DC) or alternatively in the network via Power...

Technical data Note: All types of Sensors can be operated together in networks with one Monitor (Ill. 2) or autonomously as a single unit (Ill. 3). Each Sensor has a 4 ... 20 mA output and 3 relays for connecting warning systems. This output can always be used irrespective of the arrangement. In networks, up to three Sensors can be connected directly to one Monitor without separate power supply. When connecting more than three Sensors, a PoE switch is required for each additional three Sensors. An Ethernet cable is needed for each Sensor connected to the network. A maximum of 32 Sensors can...
