Wireless gas detection

23 January 2014

Suitable for use in the oil, gas, petrochemical and utility industries, Crowcon’s new Detective+ is a free-standing, transportable multigas monitor that can be used individually or in groups to monitor up to four gases at once.

By using the Detective Net module, up to 25 Detective+ units can be linked wirelessly and positioned as much as 100 metres apart. Should wireless connection between two of the detectors weaken, the RICOCHET wireless network will 'self-heal' and automatically re-route communications via alternative devices. This creates a ‘mesh’ type network, ensuring greater reliability in safety-critical situations.
Over a dozen gas sensor options are available with the Detective+, including infrared sensors for flammable gas that are immune to the poisoning effects which plague standard flammable gas sensors.


If a dangerous gas level is detected, the Detective+ unit warns with a wailing 104 dBA siren and flashing, high intensity LED beacons which are visible from all angles. A signal is also sent to all the other units, alerting workers to the danger. In addition Detective Net transmits other fault information such as loss of signal or low battery power.
 If the signal is very weak, for example because of thick metal bulkheads, Detective Net can act as a repeater to boost the signal between units.
