Product Description

The HS21 Series integrates advanced sensing technology with robust industrial connectivity, featuring the HS21 Sensor for precise measurement and the HS21 Transmitter for real-time data conversion. This compact system supports 2 analog inputs and 4 configurable digital outputs, directly interfacing with up to 8 peripheral modules via RS-485 or Modbus protocols. Operating within 5-24V DC, it excels in harsh environments (-20°C to 60°C) across oil and gas, water treatment, and manufacturing sectors. The HS21 Sensor offers a detection range of 5-30 meters with ±0.5% accuracy, while the IP67-rated HS21 Transmitter includes a 2.4-inch LCD display and an embedded 3000mAh lithium battery for backup power. Key advantages include high immunity to electromagnetic interference and rapid response time, though compatibility with legacy systems may require protocol converters.
