TQ-821 ammonia concentration meter Introduction: TQ-821 ammonia water concentration meter is a new product developed by Beijing Shitong Kechuang Technology Co., Ltd. based on the advanced principle of American advanced production technology. The product design adopts plug-in installation, which is widely used in pipelines, ammonia tank concentration detection in open tank containers and closed tank containers, and is well applied in ammonia water preparation, ammonia water feed detection, ammonia water recovery and other processes. The ammonia concentration is directly dependent on the frequency of vibrations received by the sensor inserted into the ammonia water. The sensor's built-in temperature sensor provides temperature compensation. Features: 1. Plug-in design, plug and play 2. Continuous online measurement 3. No moving parts, maintenance free 4. Anti-corrosion design can be made for specific working conditions 5. Integrated temperature compensation 6. Passed explosion-proof certification (Exd II CT4) 7. Can be used for long pole design (up to 4m) 8. Allow the presence of small amounts of solids or bubbles 9. Not sensitive to environmental vibration 10. Inline short rod type is suitable for high pressure pipeline (maximum pressure 20Mpa) Technical Parameters: Measuring range: 0-30% vol Calibration range: according to the actual range Measurement accuracy: 0.5% vol Repeatability: 0.2% vol Operating temperature range: -50 ° C ~ +200 ° C Maximum working pressure: 20Mpa Temperature coefficient: 0.1 kg/m3/°C (after correction) Pressure effects: negligible Built-in temperature sensor: PT100 Wetted material: stainless steel, Hastelloy C22, manganese alloy 400, titanium alloy, etc. Fork body coating: standard, PTFE or electrolytic polishing Power supply: 20 – 28 VDC, 35 – 45 mA Analog signal output: 4 – 20 mA, isolated, non self-powered Output accuracy (20 ° C) : ± 0.1% of reading or ± 0.05% FS Output repeatability (-40 ~ +85 °C): ± 0.05% FS Process connection: DIN 50 hygienic quick chuck; Protection level: IP65 Housing: Aluminum alloy
