Pressure sensor 4 lines (red, blue, green, white, four lines) how to connect?
Red: Blue Power: power negative green: signal white: negative signals
Look at the instructions will know, a specific connection, if I'm not mistaken should be a positive signal output signal output power is negative power negative if the sensor type is diffused silicon word is a current source power supply, if it is the piezoresistive ceramics is the constant voltage source power supply.
Table 22 measuring resistance value between with million, a group of large resistance to the power supply signal line, another group for measuring the output signal line, first to supply any negative access to power, and then use the multimeter to measure the output millivolt signal, such as instructions, positive and negative is no problem, if there is no positive and negative exchange continue to measure, if necessary, private chat contact (weighing sensor and host is matched, no host, not the normal use of weighing sensor)
