Description
The wireless and wired automatic measurement system SJ-1000 is a system capable of connecting both digital sensors (VW sensors with frequency output) and analog sensors (mV, mA sensors). It can collect, store, and control data efficiently.
▣ Applications
- Automated measurement at sites with difficult access such as ports, bridges, dams, and subways
- Subway or urban areas with high levels of electrical noise
- Other sites such as soft ground, tunnels, and retaining walls
Composition & Characteristics
▣ Composition
- Measuring terminal
- Communication module
- Wiring panel
▣ Features
- The measuring terminal consists of 16 standard channels, and up to 48 additional channels can be connected using an external multiplexer (Mux).
- The RS485 communication module can measure up to 86 sensors through communication alone. It uses a DC 12V power supply as standard and can operate with a minimum of 9.5V.
- The built-in memory capacity is 32MB, allowing measurement of various digital and analog sensors.
