GasSafetySensor

3-026-R225

Gas type
CO2 

Sensor for monitoring the air in enclosed spaces with gas-filled operating equipment to measure different trace gases.The sensor unit detects the smallest concentrations of the gas to which it is tuned/calibrated and permanently displays the current measured value. None of the DILO sensors contain a radioactive source, so no special precautions are required with regard to radioactive hazardous substances during operation. The sensors also feature a fast response time with a stable measurement result. The settings for the warnings and alarms of each sensor can be freely configured. If the standard configuration is to be changed, this can be done via the connected monitor.

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 over Ethernet (PoE)

Note

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 be connected to one Monitor.
