Product Details:
SM-JX-V junction box can be used for weight data collection with the advantages of strong anti-interference ability, versatility, dustproof and waterproof. It adopts six-wire connection (also compatible with four-wire sensors, in addition to the standardized wiring function, it can be used to compensate and correct the four-corner deviation by adjusting the resistance value of the precision potentiometer), and it is widely used in the industries of foodstuffs, pharmaceuticals, feedstuffs, metallurgy, chemicals and so on.
Product parameters:
| Internal Wire Terminal Identification |
"EX+" Sensor's positive bridge power supply terminal |
| "EX-" Sensor's negative bridge power supply terminal |
| "SN+" Sensor's sense power positive terminal |
| "SN-" Sensor's negative inductive power supply |
| "SlG+" sensor output signal positive terminal |
| "SIG-" negative end of the sensor's output signal |
| "GND" shielding layer of the shielding cable |
| Junction box adjustment method |
Precision potentiometer VR1~VR4 can be used to fine-tune the output signals of each sensor respectively for the adjustment of the four corners of the system. Four-way dip switches SW1~SW4 are used to disconnect or connect the corresponding sensors, when they are in OFF position, the sensors are disconnected from the system; when they are in ON position, the sensors are connected to the system. |
| Differential adjustment method |
Step 1: Turn all four potentiometers to the center position before adjustment. |
| Step 2:Observe and record the millivolt signals transmitted by each sensor individually through the dip switch (when observing one of them, turn off the other three). |
| Step 3: the deviation of the larger one way to the four-way average fine-tuning (observation of which 1 way, to close the other 3 ways). |
| Step 4: Repeat step 2 and step 3 until the four-way millivolt signal is similar. |
