ZE03-Cl₂ — chlorine and corrosive exposure
ZE03-Cl₂ targets chlorine with a family-listed range near 0–20 ppm. Chlorine is reactive, so sampled tubing and protective membranes may attenuate gas before it reaches the sensor; a module mounted too far from the intended leak location may miss rapid excursions. Confirm the selected chlorine cell, environmental conditions, UART/analog scaling and calibration gas with the latest Winsen manual. End-device protective alarm behavior and enclosure material suitability must be validated independently.
ZE03-Cl₂ — chlorine-specific electrochemical signal polarity — gas-specific selection
The Winsen ZE03 electronics are a shared platform, but the Chlorine (Cl₂) electrochemical cell, calibrated units, interfering gases and analog voltage direction are model-specific.
| Specification | Manufacturer evidence | Integration concern |
|---|---|---|
| Target gas | Cl₂ electrochemical sensor fitted to ZE03 family board | Not a general disinfectant VOC or H₂S detector. |
| Calibrated class | Maker’s multigas reference matrix: 0–10 ppm chlorine | The matrix is a reference example and ordered cell specifications govern. |
| Gas response | ≤60 s response in ZE03 matrix | Total plant valve isolation may need faster or redundant interlocks. |
| Analog voltage | Chlorine variant shows descending approximately 2–0 V output over reference range | Design a specific inverse transfer function and separate loop-fault threshold. |
| Output and power | UART at 3 V TTL, analog voltage; 5 ±0.1 V input, <5mA | No universal galvanic isolation or 24 V BAS input. |
| Service and exposure | Family 2-year design life, −20 to +50 °C, 15–90%RH noncondensing | Cl₂ is reactive and may be absorbed in unsuitable sampling tubes. |
Commissioning, cross sensitivity and safety
A chlorine gas installation around water treatment requires robust sampling materials: gas uptake into moist tubing can suppress a remotely sampled measurement. Commission against chlorine reference gas and plan point placement, emergency ventilation and fail-safe notification per actual site rules. The amplified output decreases with concentration per Winsen’s listed configuration, so a broken wire cannot simply be interpreted as safely low Cl₂. Verify the gas element’s cross-sensitivity and membrane condition over its intended service life.
