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.
