1/3 2/3 3/3 Gas Detectors ProGas 4 Product code: PW-017-PG4-X The ProGas 4 gas detector is specifically designed for critical functions such as measuring, monitoring and detecting hazardous gases in industrial installations.It can operate under harsh industrial conditions where environmental parameters may vary widely (high temperatures, mist and dust). See full description Functionalities: Certificates: Product description Technical details Supported gases The ProGas 4 gas detector is specifically designed for critical functions such as measuring, monitoring and detecting hazardous gases in industrial installations.It can operate under harsh industrial conditions where environmental parameters may vary widely (high temperatures, mist and dust). It can be installed in a variety of ways: either integrated into the Gas Safety System Sigma Gas, or installed as a stand-alone detector, integrated with supervisory systems (e.g. by means of its 4..20 mA output signal or its RS-485 interface). The ProGas 4 detector has been developed to replace our earlier Sigma ProGas and ProGas devices. ProGas 4 is based on a completely new electronic design. It has a new measuring head (either ‘FL’ or ‘FH’) which is the fruit of a three year development process. This new product offers greatly improved detection capabilities. A ProGas 4 detector equipped with a pellistor sensor now offers a halved response time (T90)* and is rated among the fastest devices available. In order to prevent the condensation of moisture and its harmful effects on the sensor, the inside of the gas measuring head ‘FH’, including the sensor, is maintained at a controlled temperature of 10 °C above ambient. Other enhancements incorporated into the ProGas 4 detector include: advanced interface for external connections, power voltage range up to 50 V, mitigation of the long-term drift of catalytic sensors. * detector with the HL head with a pellistor sensor Please visit our YouTube channel where you will learn about the properties of our devices: Functionalities WATCH THE ENTIRE PLAYLIST Products WATCH THE ENTIRE PLAYLIST Realizations WATCH THE ENTIRE PLAYLIST Power supplyVoltage VCC 15 – 50 V Power PCC 0.1 – 4 W Environment Ambient temperatures Ta Specified depending on device configuration, including the sensor used 10 – 90% long term 0 – 40OC ( Storage ) Humidity 0 – 99% short term 30 – 90% long term ( Storage ) Without condensation Pressure 1013 ± 10% hPa Time parametersFor catalytic sensor: Hydrogen T90 ≤ 9 s Methane T90 ≤ 13 s Propane T90 ≤ 17 s Ethanol T90 ≤ 18 s TAlarm(T20) ≤ 3 s TAlarm(T20) ≤ 4 s TAlarm(T20) ≤ 4 s TAlarm(T20) ≤ 5 s IP IP66/IP67 (measuring head with membrane FL.M, FH.M) IP63 (other) Analog output 4 – 20 mAOutput type Sink / source ROBC_MAX (source mode) 300 Ω US_MAX (sink mode) 30 V (max. voltage between pins „S” and „-”) Digital output parameters Relays 3 x Floating contacts, 24 V / 0.3 A, Not protected against overloading Digital communication parameters RS-485 RS-485, Modbus ASCII, Sigma Bus, od 19200 Bd 7E1 Teta Teta Bus Radio communication parameters Bluetooth 4.2 Protection class III Cable glands Cable diameter range See Product marking External thread 20 x 1.5 Acceptable cables 0.5 – 2.5 mm2 (cable lugs 2 x 1 mm2 or 2 x0.75 mm2 should be used for double wires) Parameters of the hose coupling to the FL.C head 6 / 4 mm Enclosure material Aluminium spray epoxy Measuring head material SS316L / SS316L + PTFE Weight 1.3 kg Mandatory periodic inspection Every 12 months (Calibration Certificate validity) time can be shortened due to difficult working conditions Mounting To the supporting structure, 2 screw holes M6, hole spacing 118 mm with a minimum distance from the wall We recommend using mounting brackets WM8 acetonitrileacetyleneammoniabenzenebutanolcarbon dioxidecarbon monoxidecyclohexanonecyclopentanediethyl etherethyl acetateethyl alcoholethyleneethylene oxideextraction gasolineformaldehydegasolineheptanehexanehydrogenhydrogen sulfideisobutaneisopropanolisopropyl acetateJet-ALPG Liquefied Petroleum Gasmethane (natural gas)methyl alcoholn-butyl acetatenitrogen dioxidenitrogen oxidesoxygenozonepentanephosgenepropylenepropylene oxideR-gasesstyreneSulphur dioxidesulphur hexafluoride SF6tolueneVOCxylene Videos Placement and role in the system Files to downloadDatasheets:ProGas 4 Gas Detector - Datasheet Download fileUsers's manual:ProGas 4 Gas Detector - User Manual Download fileCE declarations:ProGas 4 Gas Detector - Declaration of Conformity Download fileOthers:Measurement parameters configuration of gas detectors Download file Related products Gas DetectorsSmArtGas 4Gas DetectorsReAct 4Gas DetectorsRapidGas EGas DetectorsRapidGas S
