This series of load cell transmitters is designed for professional industrial signal conditioning, converting weak millivolt (mV) signals from weight or pressure sensors into standardized industrial signals.

  • Version Differences: The Analog version (4-20mA/0-5V/0-10V) features manual calibration via onboard potentiometers. The Digital version (RS485) utilizes the Modbus RTU protocol, offering superior anti-interference and ultra-high resolution.
  • Physical Build: The core is a high-quality $38\text{ mm}$ round PCB, protected by a rugged black engineering plastic enclosure with excellent sealing properties.
  • Accessories Included: Each unit comes as a complete set, including the main waterproof box, 2 pre-installed cable glands, and sealing screws.

Pros & Cons

Pros

  • Wide power supply range DC 7-28V for flexible integration
  • Multiple output options including 4-20mA, 0-10V, RS485 for PLC/SCADA compatibility
