ZE03-C₂H₄ — ethylene as a specific gas
The ZE03 ethylene variant is cataloged for C₂H₄ rather than generic VOC concentration. A controlled ripening room should use the ethylene-specific cell calibration and actual 0–100 ppm span from its manufacturer version, with host UART/analog unit mapping. Background organic gases, humidity, temperature and cleaning agents may affect measurement and maintenance intervals. A ZE03 module’s identical-looking shell does not mean it shares the calibration of a NO₂, ozone or chlorine variant.
ZE03-C₂H₄ — ethylene gas for storage and ripening — gas-specific selection
The Winsen ZE03 electronics are a shared platform, but the Ethylene (C₂H₄) electrochemical cell, calibrated units, interfering gases and analog voltage direction are model-specific.
| Specification | Manufacturer evidence | Integration concern |
|---|---|---|
| Target gas | Ethylene C₂H₄ on an ethylene-fitted ZE03 electrochemical cartridge | The gas matrix of standard ZE03 electronics includes C₂H₄, but calibrated span must be verified by the actual supplied ethylene cell. |
| Measurement span | Order-code-specific; not published as one universal ZE03 C₂H₄ value | Do not substitute an unrelated NO₂ 0–20 ppm concentration range. |
| Interface | UART TTL 3V plus analog amplified voltage signal | A direct 4–20mA PLC channel requires a suitable external converter. |
| Electrical supply | 5.0 ±0.1 V DC; less than 5mA for the standard ZE03 module | This is module input power, not proof of universal ethylene cell span. |
| Compensation | Integrated temperature-compensating firmware for ZE03 family | Ripening-store CO₂, high RH and interfering VOC mixture can alter response. |
| Environment / nominal life | −20 to +50 °C, 15–90%RH noncondensing, 2 years nominal | Cold storage defrost and humidity condensation require independent qualification. |
Commissioning, cross sensitivity and safety
Ethylene is a plant hormone important in fruit and vegetable ripening; a few-ppm trend can matter operationally, but the supplier must supply the exact C₂H₄ calibration, cross-sensitivity and detection limit before a control threshold is asserted. Avoid copying other ZE03 gas element UART decimal scaling, baseline polarity or response time. Pair with separate CO₂/temperature/RH data for representative storage conditions and use an instrument-specific reference test.
