YD-5100 Industrial Online Seawater Salinity Meter Introduction: The industrial online salinity meter is an online intelligent salinity meter independently developed by our company. Using high-performance CPU chips and SMT chip technology to complete salinity and temperature measurement, temperature compensation, high accuracy, and good repeatability. It can be widely used for continuous monitoring of salinity values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. Features: 1. Large screen dot matrix LCD display, Chinese menu menu. 2. It can measure salinity and control upper and lower limits. 3. The screen displays the alarm status and can be accompanied by a switch ON/OFF signal output. 4. Automatic temperature compensation function: automatic 0-100 ℃. 5. Communication function (optional): Equipped with RS-485 communication interface (partially compatible with MODBUS protocol), the salinity value corresponding to 4-20 mA current output can be arbitrarily set. 6. Watchdog function: Ensure that the instrument panel does not crash. 7. The core components are all from foreign brands. 8. Factory settings can be restored. Power failure protection>10 years. Technical parameters: Measurement range: 0-300 ‰ Resolution: 0.1 ‰ Accuracy: ± 2.0% (FS) Automatic temperature compensation: NTC 10K temperature compensation at 0-100 ℃, based on 25 ℃, with adjustable temperature compensation coefficient Control interface: Two sets of ON/OFF relay contacts (passive ports). It is divided into photoelectric isolation output for salinity and temperature control signals. Signal isolation output: optocoupler isolation protection 4-20mA signal output Relay: The hysteresis of the relay can be arbitrarily set, with a relay load of 10A and 220VAC Working conditions: Environmental temperature is 0-60 ℃, relative humidity is ≤ 90% Load<750 Ω (4-20mA) Working voltage: 220V [L] or DC24V+or DC12V+ Size: 100 × one hundred and six × 168mm Opening size: 92 × 92mm Weight: 0.9Kg
