Shaw Moisture Meters launched the AcuDew Modbus RTU Dewpoint Transmitter, a high‑performance instrument engineered specifically to help compressed air users measure and monitor moisture more effectively across their plant.
Designed for compressed air dryers, distribution networks and point‑of‑use monitoring, the AcuDew Modbus RTU delivers accurate, real‑time dewpoint data directly to PLC and SCADA systems over an RS‑485 Modbus RTU network. By giving operators clear visibility of air quality at critical points, the transmitter supports improved reliability, product quality and energy efficiency in compressed air systems.
“The AcuDew Modbus RTU gives compressed air users the visibility they need to run dryers and distribution systems at peak efficiency,” said Loizos Konstantinou, Sales, Shaw Moisture Meters USA. “With robust dewpoint measurement and native Modbus RTU communication, customers can easily integrate moisture monitoring into their existing control infrastructure and make data‑driven decisions about air treatment and maintenance.”
The AcuDew Modbus RTU combines a high‑performance dewpoint sensor with a compact stainless‑steel housing suitable for demanding air compressor rooms and industrial environments. Shaw Moisture Meters designed the dewpoint transmitter for installation in compressed air lines and dryer outlets, providing fast response and stable measurements across a wide dewpoint range. In addition to Modbus RTU, the transmitter offers a 4–20 mA output, enabling use with either modern networked systems or traditional control loops.
For compressed air operators, benefits include continuous dewpoint monitoring at dryer outlets and critical points of use, direct integration with PLCs and SCADA management systems via Modbus RTU, a choice of output for flexible retrofit and new‑build projects, rugged industrial design for air compressor rooms and harsh plant conditions and improved protection of tools, valves and processes through better moisture control.
The AcuDew Modbus RTU Dewpoint Transmitter is now available for OEMs, compressed air system integrators and end users throughout North America.
