About This Product

<This is an amplifier for load cells that uses a low-noise instrumentation amplifier IC>

■Features

・It has a built-in power supply for the load cell and can be used by directly connecting to a 350Ω load cell. ・Rated output is +2.5V with no load, +4.5V with FS load, +0.5V with -FS load ・For one-sided load measurement, we can also manufacture one with +0.5V at no load and +4.5V at FS load. ・Almost the same functions and characteristics as A-820L, but supports connector connection. ・Compared to A-622L, the response frequency is higher and the residual output noise is slightly larger. ・(Connector not included) We can also accommodate load cells with rated sensitivities other than those listed above.
