Brief description of functions

1) Display content

LCD display in the main control room: the maximum/minimum diameter, average value, and ellipticity of the pipe section; the sub-item measurement values of each probe; the set steel pipe length, speed, nominal diameter, upper and lower tolerances, etc.; size fluctuation trend Prediction (after inputting the length and speed of the steel pipe, it can correspond to the position of the outer diameter in the pipe), defect analysis curve;

Real-time display of pipe length changes, real-time pipe temperature values, maximum and minimum values and out-of-tolerance dimensions at the specific position of the pipe, and the cursor can be displayed when the cursor moves to the corresponding position; real-time display of the dynamic trend of the measurement data;

When the measured data fluctuates within the set range, the data is green; when the measured data is out of tolerance (that is, beyond the set range), the colour of the data is red.

2) Alarm function

Out-of-tolerance alarm: colour warning of relevant data in the main control room and sound and light alarm of the alarm;

Calliper over-temperature alarm: main control room alarm sound and light alarm;

Pipe over-temperature alarm: main control room alarm sound and light alarm;

3) Communication interface

TCP/IP protocol, optical cable transmission, calliper to host computer;
TCP/IP protocol, optical cable transmission, host computer to the on-site LED screen.

4) Software function

Product parameter setting: parameters such as product specifications, and positive and negative tolerances can be set;

System parameter setting: you can set the faulted channel, communication port, system zero calibration, etc.;

Data storage: data recording, data export to EXCEL, historical data query, the storage time is more than 3 years; the size at a certain moment can be queried, and the time is accurate to the second.

Alarm setting: You can set the alarm thresholds for over-tolerance, equipment over-temperature, and pipe over-temperature alarms;

Correction function: automatic/manual, calibrate after inputting thermal expansion coefficient.

Automatic temperature coefficient correction: with a temperature acquisition interface, an external pyrometer can be connected, and the thermal expansion coefficient can be automatically adjusted through the collected temperature (the thermometer needs to be configured).

5) Intelligent function (requires optional intelligent module)

A SIM card can be inserted to realize remote communication with the server (with the customer’s permission, optional);

Intelligently capture the best measurement position and automatically adjust the height;

Intelligently monitor the temperature of the body, and intelligently start and stop the self-circulation cooling system and the start and stop of the external fan according to the actual temperature of the body;

Monitor the temperature of the measured object and intelligently calculate the expansion coefficient according to the temperature of the measured object (the optional thermometer is required);

Intelligently monitor the cleanliness of the lens, and automatically prompt “please maintain” when maintenance and wiping are required;

With system self-test function, regular self-tests to ensure the stability of the system and the accuracy of measurement data;

Intelligently monitor the size of the circulating air volume, and automatically prompt when the air volume is not up to standard;

It has the function of remote upgrade, and prompts to upgrade when there is an updated version of the software;

The measurement data can be observed in real-time through the mobile APP;

It can provide data docking services with customers’ MES, ERP, PDA and other systems (need to provide communication protocols);

It can be connected with an actuator to realize closed-loop control.

 

Device Configuration

The equipment has eight sets of built-in single measuring heads, mainly equipped with a self-circulating cooling system, duckbill side-blowing dust-proof system, and embedded intelligent modules.

Optional: upper computer control system, external LED display, etc., only the base can be adjusted up.
