Showa Dynamic Amplifier 5783/5793 from Japan

feature

Communication strain amplifier model 5783

High sensitivity, good stability, and noise resistance are guaranteed when using strain gauges for measurement.

Model 5683 uses a bridge power supply with a frequency of 5kHz, ensuring response characteristics from DC to kHz.

Model 5684 uses a kHz frequency bridge power supply, ensuring response characteristics from DC to 10kHz.

The automatic volume cancellation function is installed in the balance circuit.

The bridge circuit disconnection detection function is set in the system to enable measurement during a simple fault free operation (model 5793 is common).

DC amplifier model 5793

A high-precision measurement method suitable for strain sensors (measuring load, pressure, torque, acceleration, etc.).
A stable voltage of 3, 5, 9, or 10 V is used to supply the bridge power supply, with a high response frequency of realzes hircuit DC to 100kHz.
The automatic balancing function is installed in the balancing circuit and can perform high-precision instantaneous initial balancing operations.
