The main role of this circuit board is to support the shop'sDiffused silicon pressure sensorUse, high precision, small drift, processing chip and regulator tube are all imported brands, can convert the weak mV signal of the pressure sensor into a standard 4-20mA signal. Photographed if necessary, a large number of stock.
Take a look before using the instructions
First: In the welding process, it is better not to use flux, such as solder paste, and it is better to use solder wire with rosin.
Second: Because the quality of domestic washing water is mixed, it is recommended not to wash, no wash, no effect, washing may be a problem.
Third; adjust the zero full potentiometer, adjust the zero position well, pressurize to full position after adjusting the full position, you need to pressure relief to zero and then adjust the zero position, then pressurize to full level full, because in In the process Some of the tuning, the adjustment of one potentiometer will affect the other point.
Fourth: If you choose to use our sensor as a support, please see the instructions on the page. There are 4 points corresponding to the four legs. Do not take it for granted. The probability of the sequence of the 4 feet is very large Some customers themselves Go back to the drums and threw them three times, thinking that our board would not work.
Fifth: Do not reverse the zero adjustment full potentiometer position.
