Selection steps
- Identify the number of sensors, impedance, wire system and input signal
- Determine display graduations, refresh speeds and control tasks
- Matching power, communication, analog, relay and printing interfaces
- Check installation openings, enclosure and site temperature and humidity
- Agree on calibration, communication protocol and acceptance items
Installation and commissioning suggestions
- Sensor lines and power lines are laid separately
- The shielding layer is single-ended or grounded according to the system plan or in a specified manner.
- Back up the calibration parameters first and then adjust them
- Test communications, alarms and power outage recovery item by item
FAQ
What interfaces does MV-WI0015 support?
The interfaces or outputs summarized on this page are RS232, 4~20mA. Some of these functions may be optional and should be confirmed item by item when making an inquiry.
How many load cells can be connected?
It should be based on the driving capability and bridge impedance. The relevant parameters in this model information are: 1 350Ω analog sensor.
How to choose working power supply?
The power supply conditions marked in the data are confirmed according to the specific version. The site should also confirm requirements for grounding, battery backup, and data retention after a power outage.
How to choose between RS232, RS485 and 4~20mA?
RS232 is suitable for short-range point-to-point, RS485 is suitable for multi-point and long distance, and 4~20mA is easy to access the analog system; it is finally determined according to the PLC, DCS or host computer interface.
Is the display resolution equal to the system accuracy?
Not equal to. The system accuracy is also affected by the sensor, mechanical structure, calibration weight, eccentric load, temperature drift and installation. The number of display digits cannot alone be used as an accuracy promise.
Can it be used for batching or weight control?
It is necessary to confirm the relay, switching value, control logic, refresh speed and failure status. Only weight display does not mean complete control function.
Can the wireless communication distance directly copy the sample value?
No. The sample distance is usually based on specific conditions. Metal obstruction, co-channel interference, installation height and antenna position will all affect the on-site effect.
What parameters need to be checked when replacing old instruments?
Check the sensor wire system, excitation voltage, input signal, driver quantity, opening size, power supply, serial port protocol and calibration data.
How to carry out arrival and commissioning acceptance?
Check the model and interface, and complete no-load, standard load, eccentric load, communication, alarm, power-off recovery and printing or data upload tests.
What is needed for the request for quotations?
Provide the number and impedance of sensors, range and graduation value, power supply, display mode, output interface, number of control points, installation method and explosion-proof or waterproof requirements.
Ordering instructions
When ordering, please indicate the sensor quantity and impedance, range and graduation value, power supply, display, communication/analog/relay, printing, installation method and explosion-proof and waterproof requirements; interfaces marked as optional must be written into the order.
