The zero point can be adjusted by the zero‑adjusting potentiometer to improve the accuracy, and there will be no zero‑point drift to meet customer needs
A potentiometer is used to amplify the input , the magnification is up to 1000 times, and can be adjusted only through a potentiometer
The input range is wide. This product uses AD620 to amplify, which can amplify microvolts and millivolts. Possess higher amplification accuracy and better linearity than the LM358 on the market, and the maximum voltage output range is ±9V
The module uses 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other power loads
Mini type, size is 32 x 22mm, there are 4 3mm positioning holes evenly distributed around, 2.54mm standard spacing on both sides
