Town Gas Application | |
| Measurement object | Measurement and control of WI or the calorific value of fuel gas for town gas. |
| Measuring Range | ۳ to 62 MJ/Nm3 |
| Sample gas condition | Dust: 5 mg/Nm3 or less< Temperature: 50℃ or less Humidity: dew point of 0℃ or less Pressure: (1) 10 to 20 kPa: standard, (2) 10 kPa or under: with pump, (3) 100 to 600 kPa: with pressure reducing valve |
| Range | Select scale range (Span): General Gas: 30 to 50% of maximum value of the span. Butane or Butene + Air:20 to 30% of maximum value of the span. Propane or Propylene + Air: 25 to 40% of maximum value of the span. |
| Output signal | ۱ to 5 V DC, 4 to 20 mA DC (simultaneously), non-isolated, load resistance 750Ω or less |
| Alarm Contact Output | Flame off alarm; 100 V AC, 5 A, closed when alarm occurs Temperature alarm; 100 V AC, 3 A, closed when alarm occurs |
| Contact Input | Remote ignition (custom order); 24 V DC, 0.1 A or more |
| Sample Gas Flow Rate | Approx. 10 l/min |
| Utility | Instrument Air: Approx. 50 Nl/min, pressure 300 to 700 kPa, dew point of 0℃ or less Power Supply: 100 V AC ±۱۰%, single phase, 50/60 Hz, 860 VA max. |
| Panel | Construction: For indoor installation, rack panel. |
| Ambient Temperature | ۰ to 40℃ and no rapid change in ambient temperature is allowed. |
| Repeatability | When the calorific value means 6.3 MJ/Nm3 or higher, Calorific : ±۱٫۰% of measured value WI : ±۰٫۵% of measured value |
Steel Mill Application | |
| Measurement object | Measurement and control of WI or the calorific value of fuel gas for a steel mill. |
| Measuring Range | ۳ to 62 MJ/Nm3 |
