Product Description

The Weihai WHDM04 Transmitter is a versatile industrial device designed for dual-sensor monitoring, featuring two independent inputs for simultaneous data acquisition from connected sensors. As a WHDM04 Dual Sensor Transmitter, it supports direct integration with up to two external sensor modules, enabling real-time measurement of parameters such as temperature, pressure, or flow. The device operates on a 12-24V DC power supply and functions reliably in harsh environments (-20°C to 60°C), making it ideal for oil/gas, chemical processing, and water treatment industries. Equipped with WHDM04 RS485 Sensor communication, it enables Modbus RTU protocol for seamless network integration. Key advantages include high accuracy (±0.5% FS), robust IP65-rated housing, and a compact 120mm x 80mm panel design. The transmitter offers a 30-meter signal transmission range and accommodates sensors with detection distances up to 50m, though it lacks built-in battery backup and display interface.
