Product Description:Load cell

Wiring method for PFTL101BE-2.0KN

There are two types of load cells: 4-wire and 6-wire, and 4-wire and 6-wire for the module or repeater. The principle is: the sensor can be connected to 6-wire, not 4-wire, and the 4-wire must be shorted.

The general load cell is a six-wire system, when connected to a four-wire system, the power line (EXC-, EXC+) and feedback line (SEN-, SEN+) will be shorted respectively.

EXC+ and EXC- supply power to the load cell, but due to line losses between the load cell and the load module, the voltage received by the cell will actually be less than the supply voltage. Each load cell has a mV/V characteristic where the mV signal it outputs is closely related to the voltage it receives. SENS+ and SENS- are actually a high impedance loop within the load cell that feeds the voltage actually received by the weighing module back to the weighing module. Assuming that EXC+ and EXC- are 10V, line loss and the load cell is 2mV/V, the actual output signal from the load cell is ()*2=19mV instead of 20mV. 19mV is then used as a large range within the load cell, provided that the load cell feeds the actual voltage back to the weighing module via a feedback loop. The shorting of EXC+ to SENS+ and EXC- to SENS- on the load cell is limited to situations where the sensor is close to the weighing module and the voltage loss is very small, otherwise there is an error in the measurement.
