Overview

DTZ-01 / DTZ-02 type automatic calibration system for thermocouples and resistance temperature detector is mainly used for the Automatic calibration and verification of temperature sensors such as working thermocouples, industrial resistance temperature detector, glass liquid thermometers, bimetallic thermometers, and pressure thermometers.This system can control 1-10 calibration furnaces simultaneously. Each calibration furnace can verify 10 thermocouples at a time. It supports the grouped verification of various industrial platinum and copper resistance temperature detector, and can verify 100 thermal resistors at a time, meeting the requirements of batch detection in a short period.

This system adopts a number of technological innovation achievements of our company. Both the system software and hardware technologies are independently developed by our company, and we have full independent intellectual property rights. It has a series of characteristics such as advanced design, reasonable structure, complete functions of the system software, convenient operation, accurate and reliable value transfer, strong anti-interference ability, and flexible configuration. It can automatically realize the functions of data collection, data processing, data storage, and the generation of calibration/verification certificates, improving efficiency while providing customers with comprehensive technical support.

in accordance with the requirements of AFS ‘AMS2750F Aerospace Materials Specification for High Temperature Measurement’, cited in ‘ATSM E230/E230M-23’.

2.Quick copy function.

After opening the original calibration record, it can be quickly copied to the inspected information with one key.

3.It supports the combined calibration of low and high temperature sections of thermocouples, Automatically selects the constant temperature source and standard, and Automatically combines the original reports;

it Automatically selects the standard platinum resistor as the standard below 300℃, and Automatically selects the standard thermocouple for the high temperature area, without the need of manually modifying the standard.

4.Supports customised setting of the level of the inspected sensor,

which is convenient for customers to screen the accuracy of the sensor.

5.Compensating conductor database management function: pre-set compensating conductor correction parameters, according to the number to quickly select the compensating conductor and Automatically enter the correction value.

6.Support 10 temperature detection points of free setting,

high and low temperature detection points can be Automatically switched between the standard and the thermostat source.

7.Calculation of the tolerance according to the regulation: Corresponding tolerances are Automatically generated when measuring temperature points outside the regulation are added.

8.After the test is completed, the thermocouple grade is Automatically determined according to the error of the inspected thermocouple.

9.Intelligent search function:

according to the inspected sensor information (inspection completion time, inspection category, index number, grade, inspection certificate number, pass or fail) and other entries can be a key intelligent search.

10.The test process can be based on the examined data failed,

poor data repeatability options for selective prompting of the results.

11.The system software has the function of Automatic correction of temperature control deviation in the inspection process;

ensure the accuracy of data in the inspection process.

12.The title of the inspected information can be customised;

the title of the inspected information is rich in entries (factory number, specification, manufacturer, inspection unit, appearance, date of inspection, insulation resistance, management category, special management), which can be independently selected and defined to meet the needs of different customers.

Professional Customized Report and Certificate Functions

1.Automatic generation of test, calibration and self-definition logs, with multi-media audible alarms and electronic signatures.

2.The test record table can be customised to name, so that it is easy to quickly find different types and contents of the original test records.

3.A Word certificate in the standardised format is Automatically issued upon completion of the test.

4.Function of previewing WORD test/calibration certificates.

5.Supports traceable modification of the original calibration record sheet, Automatic derivation of calibration conclusions after modification of the original data, and Automatic recording and saving of modified data records for easy subsequent access and traceability.

6.Customised Word certificate template, customers can customise the word certificate information.
