Features
Real-Time Simultaneous Measurement at a Maximum of 100 Points
By utilizing the advantage of wireless measurement, up to 100 points (100 units) can be monitored simultaneously in real time.
- * Sampling time can be set for each unit.
- * Up to 30 units when sampling time is less than 1 sec.
Stores an Amplifier and a Bridge in a Compact Body
Equipped in a compact body, this unit includes a high-performance amplifier and a high-precision bridge using the high density mounting technology. It contributes to space saving at installation sites and improves efficiency of operation.
Measurement range: ±20000 µ strain
Three models supporting various measurement methods
- 120 Ω model supporting 120 Ω strain gauges
- 350 Ω model supporting 350 Ω strain gauges
- Full bridge model supporting the four-active gauge method
Supports Two-Active Gauge Method
Equipped with four connection terminals, this unit supports both one-active gauge method (two-/three-wire connection) and two-active gauge method (dummy gauge for temperature compensation).
Supports the four-active gauge method (full bridge model only)
The series supports the four-active gauge method, so strain transducer sensors can be connected.
