Description
- Up to 4 units of 350 Ω strain-gage type transducers connected independently to respective amplifier circuits.
- Switchable indicated value, channel to channel or the totalAnalog voltage output of all channels and the total
- High/low limit comparator for the total value
- High-speed output suitable for control, I/O delay approx. 10 ms
- Sensor check and self-test functions
- Indication range-19999 to 19999 with decimal point anywhere
Features
The WGC-140A is a high-speed processing at 2 ms, a compact 4-channel Instrumentation Amplifier, which can calculate the physical quantities of load cells, etc.
It is suitable for measurement and control of the load applied to each column of press and the total load or for tension control by measurement of load balance and total load in various fields.
