Product Overview
The OHTS1080 is a wind speed measurement transmitter based on a three-cup mechanical structure, featuring an aluminum alloy enclosure and bottom cable exit design for long-term outdoor environmental monitoring. The device incorporates a bearing rotation mechanism that converts cup wheel rotational speed into electrical signals via photoelectric or magnetoelectric conversion principles.
Internal circuitry processes these signals and outputs standard Modbus RTU protocol data through an RS-485 interface. The enclosure surface undergoes anodizing or spray coating treatment, providing UV resistance, rain and snow resistance, and chemical corrosion resistance, making it suitable for wind speed parameter acquisition in meteorological, environmental protection, and industrial field applications.

FAQ
Q: Can the device be disassembled for maintenance or calibration?
A: Strictly prohibited to disassemble the device or touch the sensor core body to avoid permanent damage or calibration failure. The device is factory-calibrated and sealed to maintain measurement accuracy.
Q: What precautions should be taken during installation?
A: Power must be disconnected before installing or removing the transmitter to prevent circuit damage from live operation. Ensure the device maintains a horizontal orientation during mechanical installation to guarantee wind speed measurement accuracy.
Q: What environmental conditions should be avoided?
A: Water ingress will cause irreversible damage; strictly prohibited to use in condensation or extreme temperature environments; prevent thermal shock. The device is designed for relative humidity 0% RH ~ 95% RH non-condensing conditions.
Q: Are there any electromagnetic interference considerations?
A: Installation location should be far from high-power electromagnetic interference sources such as frequency converters and high-power motors to avoid measurement errors. The device incorporates EMI suppression but requires proper installation environment.
Q: Can this device be used as a safety device or emergency stop device?
A: This device is strictly prohibited from use as a safety device or emergency stop device, and shall not be used in applications where equipment failure may cause personal injury. It is intended for monitoring and data acquisition purposes only.
