Features • IP54 rated • Simple to install, maintain and use • Fully temperature compensated for zero and span These detectors are small light weight devices which are easy to maintain, service and operate. Gas types detected Used in conjunction with a controller, the iQguard Carpark Detector can run with variable speed drives on exhaust fans to reduce excess power usage. Carbon Monoxide (CO) Nitrogen Dioxide (NO2) 0 - 150ppm 0 - 10ppm Refrigerant gas detectors Austech’s infrared refrigerant gas detectors are highly selective and accurate instruments which detect specific refrigerant gas leaks and a broad range of refrigerant gas types. Features: • Infrared technology for accuracy • Highly selective for gas type Gas types detected: • Most common refrigerant gases Sensors are set specifically to respond to the target gas to reduce false alarm situations which are a common issue with lower performing technologies such as semiconductors. Flammable gas and vapour detectors Austech’s 79-2500 range of Exd Group 2 / Zone 1 certified flammable gas detectors are available in Infrared and Catalytic detection versions. Certification • ANZEx 11.4101U / IECEx SIR 09-0118U (Catalytic) • IECEx Exd IIB T6 40oC (Infrared) The detectors feature a local display (non-display options also available) and calibration functions with 4-20mA loop output; inbuilt alarm with relay options for local alarm control; is user programmable via magnetic tool; backlit by LCD providing full information display of gas, alarm and mA output. Measuring range • 0-100% Lower Explosive Level (LEL) • % Volume specific to gas type Features • Flameproof • Remote display option • Non-intrusive calibration and checking via magnetic tool Infrared detector features • Immune to catalyst poisons • Not affected by high gas concentraions (100% v/v) • Low maintenance requirement • No gas confidence testing • 4-20mA source into 600 ohms • Temperature stable condition not affected by humidity Gas types detected • Butane • Diesel • Ethane • Hydrocarbons • Jet fuel • Methane • Petrol • Propane • Other hydrocarbons • CO2 0-5%v/v Available in IR model Calibration gases and test kits 4 and 12 channel controllers We provide a range of calibration gases and test kits complete with accessories and a wide range of gas mixtures traceable to either Australian or NIST (USA) standards with full documentation are available on request. Features • A large range of gases available • Gas mixtures to Australian and NIST standards • Calibration kits include valves, regulators, flow meters and tubing Austech’s 4 & 12 channel system controllers are compact units designed to accept any two or three wire sensor or transmitter that gives a 4-20mA output, with relay outputs on board for alarm events and programmed response. Typical sensor/transmitter combinations include Austech’s detectors for combustible gas, oxygen, toxic gas, flame detectors as well as temperature and humidity transmitters. designed to Australian Standards for use with our iQguard Car Park Detector as well as a flameproof version for hazardous areas. The controllers have 4 or 12 4-20mA inputs, two 4-20mA outputs and four relay outputs for common warn, alarm, high alarm and fault conditions. Three push buttons, four LEDs and a sounder provide status and control functions. A two line alpha-numeric display provides continuous status readouts of each monitored channel, with a choice of two user-configurable formats. A specific display mode shows all input readings and status simultaneously. Larger scale controllers and PLC’s are also available. Features • Accommodates up to 4 or 12 gas detectors • Microprocessor controlled • Accepts inputs from combustible and toxic gas detectors, flame detectors and any 4-20mA device • Two line alpha-numeric display • Retains data on loss of power • Fully programmable from front panel • Built in self diagnosis • Fan control logic • Software ‘voting logic’ output • Optional RS485 Modbus digital interface • Optional data and event logging The controllers come in carpark versions Austech Instruments Unit 2, 71 Prince William Drive Seven Hills, NSW 2147 Telephone: +61 2 9620 9600 [email protected] aus-tech.com.au group of companies
