The ZS-RTU Series Multi-Point Temperature and Humidity Collector, developed and manufactured by Langfang Zhaosui, represents a new generation of intelligent data acquisition devices for grain storage and industrial monitoring. Designed with GRE Fourth-Generation Drive Circuit and optimized driver programs, this series focuses on solving the challenges of complex electromagnetic interference, long-distance wiring, and sensor submersion scenarios. It delivers stable and accurate performance where traditional collectors often fail.
Exceptional Capacity and Distance
One of the key advantages of the ZS-RTU series is its powerful driving capability. A single device can manage:
- Up to 800 sensors with the ZS-RTU-800P model
- Up to 1600 sensors with the ZS-RTU-1600 model
This makes it ideal for large-scale grain depots and industrial storage facilities, where hundreds or even thousands of measurement points are required. In addition, it can support sensor cabling over 1600 meters in length, ensuring stable communication even in extremely large warehouses or silo installations.
High Compatibility with Industry Standards
The ZS-RTU series is fully compatible with DS18B20 and other digital temperature and humidity sensors. All sensor data can be seamlessly converted into the standard MODBUS protocol, making integration with upper-level control systems extremely easy. Whether it is SCADA software, industrial PLCs, HMI touch screens, or centralized monitoring systems, the ZS-RTU collector provides reliable, standardized data output.
Robust Performance in Harsh Environments
The device is engineered with industrial-grade protection and multiple adjustable parameters, enabling stable operation in a wide range of conditions：
High-interference sites with motors, inverters, or heavy electrical equipment
Long-distance layouts in flat warehouses, silos, or tunnels
Humid or water-exposed environments, where conventional devices may fail
This adaptability makes the ZS-RTU series not only suitable for grain monitoring but also for chemical storage, cold chain logistics, greenhouse monitoring, and industrial process control.
Smart and Reliable Operation
Equipped with power-off protection and local data storage, the ZS-RTU collector ensures that historical data is preserved even during unexpected outages. Its modular design allows flexible expansion, enabling multiple collectors to be cascaded together for centralized management of massive data sets.
Furthermore, the system supports remote parameter adjustment and firmware updates, reducing the need for on-site maintenance and ensuring long-term cost savings for operators.
