ABB 氧化鋯分析儀 AZ25 AZ20 產品簡介

閱讀:1623          發布時間:2017-10-20
  The Endura AZ20 is the latest in a long line of high-quality, combustion gas analyzers from ABB.
 
  The sensor, based on a zirconium oxide cell, is mounted at the tip of the probe that is inserted in the flue duct. The resulting direct, in situ measurement provides accurate and rapid oxygen reading for combustion ** / optimization and emissions monitoring purposes.
 
  Endura AZ20 has been designed for extended periods of maintenance-free operation. The modular design with reduced component count improves the reliability and robustness of the system and simplifies breakdown repair if it occurs.
 
  Kits containing all the parts needed to complete on-site repairs are available from ABB, ensuring that service personnel can effect repairs quickly and efficiently at minimum cost. The Endura AZ20probe has retained an easy-access cell arrangement, similar to the proven ZFG2 probe. This ensures cell replacement can be carried
 
  out on-site using readily available, basic hand tools, even after long periods of high temperature operation.
 
  The Endura AZ20 oxygen probe measures oxygen*** in flue gas using an in situ 'wet analysis' method. The 'wet analysis' method avoids measurement error (typically20% of reading higher than the actual value) that is ***by a sampling system using the 'dry analysis' method.
 
  For customers with an existing installed ZFG2 probe with a ZMT or ZDT transmitter, a 55 V heater version of the Endura AZ20probe (the Endura AZ20 / ZFG2 replacement probe) is available.
 
  System equipment comprises a (flue-mounted) Endura AZ20probe *** by an integral or remote transmitter. During operation, a zirconia cell within the probe is held at a constant temperature of 700°C (1292 °F) by a probe heater
 
  thermocouple assembly. If the heater ***circuitry or software fails (unsafe), the probe heater power supply is switched off, ensuring the system fails 'safe' and protects the heater from an over-temp failure.
 
  An output generated at the zirconia cell is processed in the transmitter giving a locally displayed O2 reading and a 4 to 20mA retransmission signal over any range between 0 % and 100% O2.
 
  Optional automatic calibration (AutoCal*) enables automatic,semi-automatic or manual calibration to be performed using a probe-mounted gas*** manifold mounted within the probehead. Calibration sequencing is software-*** from thetransmitter.
 
  Optional restrictors (where fitted*) in the probe head *** thetest gas and reference air flow without the need for flowmeters.The probe requires only preset test gas and reference airpressures of 1 bar (15 psi) to maintain a constant flow of 2.2 l /min (4.662 scfh). This flow is not affected by changes in themeasured gas pressure of ± 0.35 bar (5 psi).
 
  The Endura AZ25 combustion oxygen analyzer is the latest ina long line of high-quality, combustion gas analyzers fromABB. The AZ25 is designed to measure oxygen **** high temperature furnace atmospheres.
 
  The sensor, based on a zirconium oxide cell, is mounted at thetip of the probe that is inserted directly into the furnace. Theresulting direct, in-situ measurement provides an accurate andrapid oxygen reading, for combustion optimizationand process quality ** purposes.
 
  The in-situ technique provides a true oxygen measurementinside the process. It eliminates 'equilibrium shift' that iscommon to systems in which gas samples are extracted andcooled before measurement.
 
  Reference air (500 to 1000 ml/min [1 to 2 ft3/hr]) is required foraccurate operation and can be supplied from an ABBmains-powered pump unit or a flow regulator unit.
 
Unique integrated automatic calibration
 
  The Endura AZ25 automatic calibration system eliminates theneed for the expensive ancillary ***forautomatic calibration on ***l flue gas oxygen analyzersystems. ABB’s fully integrated, automatic calibration feature
 
  ** the test gas sequence and detects test gasavailability, eliminating incorrect calibrations due to loss of testgas. Integrated automatic calibration secures the oxygenmeasurement, providing complete confidence in the analyzer's
 
  performance.
 
  Long-term operation without technician ** minimizesoperating costs, total cost-of-ownership and optimizes systemaccuracy. A significant proportion of service visits to ananalyzer result in 'no fault found'. Endura AZ25's high-quality
 
  manufacture, advanced diagnostics and automatic calibrationis targeted at reducing this wasted effort and cost.
