Feature
- Precision die-cast aluminum transmitter housing with plastic sprayed surface, suitable for high precision level and harsh environment.
- Adopting anti-interference power supply design technology, the load cell weight transmitter has good electromagnetic compatibility (EMs).
- The wiring adopts terminal and aviation plug, and there are mounting holes in the shell. In addition to the characteristics of a normal load cell transmitter, it also reduces the harmonic interference generated by frequency converters and so on.
- The analog output of this load cell transmitter can be 0-5V, 0-10V, 0-±5V, 0-±10V, 4-20mA (optional).

Wiring Instruction

As the figure above shows: There are two wiring terminals J1 and J2 in the whole board diagram.
LEFT J1 is the terminal connecting the sensor:
PB |
Connect the sensor shielded wire |
blue wire |
E+ |
Connect the positive wire of the sensor excitation power supply |
red wire |
E- |
Connect the negative wire of the sensor excitation power supply |
black wire |
S+ |
Connect the positive wire of the sensor signal output |
green wire |
S- |
Connect the negative wire of the sensor signal output |
white wire |
RlGHT J2 is the terminal connecting the transmitter to the power supply and output:
IOUT |
Connect the transmitter current output positive wire |
white wire |
VOUT |
Connect the positive voltage output wire of the transmitter |
white wire |
(current and voltage are only output at the same time) |
GND |
Connect the negative wire of the transmitter power supply |
blue wire |
24V |
Connect the positive wire of the transmitter power supply |
red wire |
There are 2 adjustable resistors in the whole board diagram: RP2 is gain adjustment, RP1 is voltage zero adjustment.
Tips: What are the common faults and troubleshooting methods of load cell weight transmitter?
Common faults include no signal output, unstable output signal or large error.
- No Signal Output: Check whether the power supply is normal, whether the wiring is correct, and whether the load cell transmitter is damaged.
- Unstable Signal: Check whether there is electromagnetic interference, whether the load cell sensor is subject to external vibration, and whether it is well grounded.
- Excessive Error: Is the calibration correct, is the sensor overloaded or damaged. Regular maintenance and calibration can ensure measurement accuracy and equipment stability.
