for DC 12V 24V 4-20mA Load Cell Weight Sensor Amplifier Module Load Cell Transdu

Features: Housing and wire connectors are waterproof design, good sealing, suitable for harsh environments Look beautiful, durable, anti-jamming performance Ultra- high-precision op amp circuit, high accuracy, good stability The power supply has reverse polarity for protection, surge for protection, overcurrent protection Suitable for weighing, pull pressure, torque, and other strain sensor. Technical Parameters Working voltage: for DC 12-24V Output signal: voltage (0-5V, 0-10V, 1-5V, 5V) 4-20ma input signal:sensor sensitivity 2.0MV/V output incentive:5V(E+) / 5(E+) Operating temperature range: -20 - 80 Operating Humidity: 10% RH-90% RH (non-condensing) Accuracy: better than 0.1% F.S Precision is better than 0.05% F.S PCB Board Size :9*5.2*2.5cm Interface definition S+: Signal + S-: Signal - E+: Excitation Power supply+ GND: Excitation Power supply- GNDD: Shield 24V: Power supply+ GND: Power supply- IO: Current Output VO: Voltage Output GNDD: Shield Gear selection: Dial switch turn OFF , V0 output 0-5v , 1 turn to ON V0 output 0-10V 1 and 2 both turn to OFF VO output 0-5v IO output 4-20MA About debugging 1 zero adjustment First of all, make the system is in the idle state, adjust the marking "ZERO" potentiometer to adjust the zero offset. The multimeter is used to measure the output voltage or current, let show a value as close as possible to the zero value display. Or change the magnification zero change will become big. 2 gain adjustment The system loading a certain weight value (the recommended range: 80% ~ FS), the calculation of the output current value according to the load weight and the maximum weighting value relation, using the digital multimeter monitoring output, potentiometer to adjust amplifier gain spin labeled "SPAN". 3 the retest The system is in the idle state, measuring the zero output; loading a certain weight value, output voltage measurement whether fluoride expectation magnification If not, repeat steps 1, 2 adjust again. Signal processing A good transmitter, first of all to filter, this module uses inductance + capacitor filtering, can effectively suppress power supply ripple interference, with overcurrent and anti-reverse protection Package included: 1 * Weighing Sensor Transmitter Tensile Pressure Strain Amplifier Transducer
