HEAVY-DUTY PRESSURE TRANSDUCERS Honeywell has expanded its line of pressure monitoring sensors designed to minimise the total cost of pressure management for HVAC and refrigeration systems. The PX3 series heavy-duty pressure transducers convert pressure into an analog electrical signal. The sensors feature a brass housing and can support multiple configurations to help end users minimise implementation and production costs. They feature low-current consumption to help reduce system energy costs, while also enhancing product life when used in battery-driven systems. The pressure transducers are compatible with many nextgeneration, low global-warming potential (GWP) refrigerants, including Honeywell’s Solstice N40. The line expands the sensors’ pressure range to 1 to 50 bar (15 to 700 psi). The series also offers: freeze-thaw resistance to frost, which is commonly found in refrigeration systems; high electromagnetic compatibility (EMC) radiated immunity to operate consistently in the presence of wireless signals, radiofrequency communication and electrical devices; shock and vibration tolerance; a wide operating temperature range; and durable design, with a high surge immunity at ±1000 V line to ground per IEC 61000-4-5.

EMISSIONS ANALYSER The J2KN series analyser utilises electrochemical sensors to measure exhaust emissions — most commonly O2, CO, NO, NO2 and SO2 gases — and has an available NDIR bench for measuring CO2, high CO and CH4. The robust filtering system, along with the Peltier gas cooler and 9 V high­flow pump, ensures a clean sample and high flow rate, which is necessary for accuracy and repeatability. The sensors are monitored, which compensates for temperature changes in even harsh testing environments, and the CO sensor has a dedicated fresh air pump that is activated if a maximum concentration limit is exceeded (usually 4000 ppm). The robust sample conditioning features, high-speed flow rate and sensor monitoring ensure high performance for the ecom-J2KNpro. The product is fully loaded with sensor options and features, which allow it to be used in many different applications. These applications include emission testing on stationary engines, generators, compressors, boilers, burners, turbines, heating equipment, pumps, diesel engines, mining equipment (to control DPM), construction equipment, laboratory combustion equipment, alternative fuels research and more. The analyser is also used for fuel efficiency testing, combustion tuning, maintenance checks and emissions compliance reporting. The types of fuel burnt that can be tested on the J2KN series include natural gas, oil, diesel, coal, wood, biomass, butane, propane, biodiesel and other alternative fuels. Gasoline emissions may be tested with the ecom-J2KNpro industrial, but this requires the NDIR bench (for CO). AMS Instrumentation & Calibration Pty Ltd www.ams-ic.com.au
