Load cell wiring problem

The general sensor is six-wire. When connected to a four-wire system, the power cable (EXC-, EXC+) and the feedback cable (SEN-, SEN+) are shorted. SEN+ and SEN- are used to compensate for line resistance. SEN+ and EXC+ are pathways, and SEN- and EXC- are pathways.
There are two types of sensor outlets: 4-wire and 6-wire. The wiring of the module or weighing transmitter is also available in 4-wire and 6-wire. To connect to 4-wire or 6-wire, you must first see how your hardware requirements are. It should be: can not connect 4 lines of 4 lines, must be connected to 4 lines will be shorted.
EXC+ and EXC- supply power to the load cell, but due to the line loss between the weigh module and the sensor, the voltage actually received by the sensor is less than the supply voltage. Each load cell has a mV/V characteristic, and its output m number is closely related to the received voltage. SENS+ and SENS- are actually a high-impedance loop in the weighing module, which can actually weigh the module. The received voltage is fed back to the weighing module. Assume that EXC+ and EXC- are 10V, line loss is 0.5V, and sensor is 2mV/V. In fact, the sensor output zui large signal is (10-0.5)*2=19mV instead of 20mV. At this time, the internal module of the weighing module will take 19mV as a large range of Zui, provided that the sensor must feed back the actual voltage to the weighing module through the feedback loop. Shorten EXC+ and SENS+ on the weighing module, and short-circuit EXC- and SENS-, only when the distance between the sensor and the weighing module is close, and the voltage loss is very small, otherwise there is error in the measurement.

Traditional convenience foods need to be soaked in boiling water for consumption. Some special people, such as wilderness adventures, tourism, troops, and police officers, cannot be eaten without boiling water. Self-heating Rice does not need boiling water when cooking, no need for thermal power, tear open the outer packaging, pour the pure water bag inside it into the heating bag, the water and the heating bag will automatically mix and heat up, steam the rice and the dishes, 8-15 minutes Edible.
Decommissioning the ingredients of the Self-Heating Rice heating package: Inventing a multi-purpose self-heating bag, mainly using roasting diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt to form a bag, which can be heated to 60 °C It can be used for heating in winter, medical hot compress, adding quicklime, sodium carbonate and water. The temperature can be raised to 120 °C to heat meals or steamed food. The temperature is kept for 20 minutes to 100 ° C for 60 minutes and 60 ° C after 60 minutes. The material used in the winter heating and hot compressing can be repeatedly used, and after being used, it can be mixed with quicklime and sodium carbonate, and then heated to heat the food.
