Model NH3 - Online Analyser

From

0

The OnlineNH3 is used for a quantitative determination of NH3 in livestock buildings, digestion towers and biogas plants. The sampling can be carried out at one, two or more selected measuring points. This measurement serves as the basis for water treatment and the control of maximum threshold values.

he measurement of NH3 works with selective, electrochemical sensors. The mobile microcontroller unit includes a data acquisition and data transmission tool, digital and analogue input connections for various measurands as well as digital and analogue alarm output connections (4 - 20 mA) for industrial process monitoring and control.

The OnlineNH3 enables an increase of efficiency regarding treatment methods through a quantitative measurement of the NH3-value in front and after filter plants and through a measurement of the individual process steps of a biogas plant, respectively. Hence, maintenance and cleaning cycles can be accurately identified and optimized.

Applications

  • Livestock facility
  • Control of digestion towers
  • Slurry storage
  • Biogas plant
  • Elimination of smell nuisance
  • Elimination of hazard sources

Advantages

  • Data acquisition directly in the data logger of the analyzer for several months
  • Long operating life of the sensor through intermittent gas path control
  • Low maintenance effort by automatic zero point compensation
  • Optional combination with other sensors (e. g. hydrogen sulfide or hydrocarbon/odor sensors)
  • 4…20 mA output signal to transmit the NH3-signal into customers' control system
  • Active gas sampling through a transfer line of up to 50 m length and from a depth of down to 10 m
  • Integrated rinsing steps to ensure a current sample for analysis at all times
  • Optional extension for multiple measuring points
  • Selective electrochemical sensors
  • Data transmission via GSM

  • Online determination of the NH3concentration at the source (e. g. building for livestock) and at the drain (e. g. exhaust air chimney after a biofilter)
  • Very high sensitivity (below 1ppm) with most precision
  • Selective electrochemical sensors
  • Integrated rinsing steps for the certainty of a steady current sample for analysis
  • Automatic zero-point-compensation
  • Arbitrary measuring cycles/ amount of measurements per day
  • Data logger for several months
  • Output of the NH3value as 4…20 mA-signal
