Accuracy, measurement range, electrical outputs, probe length and installation environment depend on variant and current revision. Check manufacturer data prior to equipment specification.
LFH10A economy integration
For this economy transmitter, prioritize the confirmed measurement ranges, RH/temperature output mapping, supply voltage and housing position rather than inferring the more expensive LFH10/LFH30 specification. Wall mounting near heat sources or wet areas may bias the air sample. Establish actual factory options and host calibration steps; reduced cost is not evidence of a particular drift, protection or Ex rating.
LFH10A — economical model-specific RH and temperature data
| Humidity | 0–100% RH; ±3% RH at 20°C and 20–80% RH; response within 10 seconds under reference airflow. |
|---|---|
| Temperature | 0–50°C or −20 to +60°C range variants; digital ±0.3°C at 0–60°C. |
| Electrical | 4–20 mA, 0–10 V or Modbus RS485 variants; voltage/RS485 supply 15–35 VDC or 24 VAC ±20% via isolated AC. |
| Mechanical | Wall, duct and split options, ABS housing, polymer filter and optional display. |
| Environment | −20 to +60°C, 5–95% RH non-condensing, IP65. |
Engineering note: Do not copy higher-end LFH30 ±2% RH into economical LFH10A. Ensure RS485 address and DIP switch selection match the specified device; correct power and load depend on the output.
