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.

DTZ-01S Precious Metal Thermocouple Wire Automatic Calibration System is a fully automatic metrology and testing platform tailored for the production and manufacturing process of precious metal thermocouple wires. Its core technology focuses on precious metal platinum-rhodium wire/platinum-rhodium thin wire thermoelectric potential measurement, paired platinum-rhodium thermocouple calibration, standard platinum-rhodium thermocouple calibration, and industrial precious metal thermocouple calibration/verification.

The system integrates core components such as multi-channel low-potential scanner, digital multimeter, and calibration furnace (including high-temperature furnace and palladium spot furnace), and builds a full-link solution from raw material wire property testing to finished thermocouple terminal product calibration. The system adopts a modular control architecture, supports a variety of application scenarios such as Automatic mapping of platinum-rhodium wire thermoelectric potential-temperature relationship curves, standard thermocouple value transfer, and industrial-grade precious metal thermocouple on-site calibration, and realizes a full-process Automatic, high-precision, and intelligent metrology guarantee system from single-wire testing to paired component testing.

The Functions of System Software

1.Support single-furnace Automatic calibration system, double-furnace Automatic calibration system, group furnace Automatic calibration system;

Support mixed calibration, group calibration; support a variety of models of imported digital tables and high-precision temperature measurement instrument communication protocol.

2.Support independent selection of different models of calibration furnace and standard at the same time. Support multimedia sound alarms, intelligent prompts for startup, completion and error during the testing process.

3.Support Automatic channel checking and screening function, and prompts for abnormal data content after channel checking is completed. It is equipped with strong inspection function and over-temperature protection。 function, which is convenient for customers to test for diversified specific needs.

4.Support electronic signature function. With power-down protection function, you can choose whether to continue testing/calibration after power supply is restored according to your needs.

Support a variety of thermocouple reference end processing methods, supports zero degree thermostat compensation or Automatic room temperature compensation.

5.Support group testing/calibration function, a one-time inspection of 100 pcs, divided into 10 groups of testing/calibration of various types of industrial platinum, copper thermal resistance (Pt10, Pt100, Pt-X, Cu50, Cu100, Cu-X), to enhance the testing efficiency.

6.Support the function of mixed calibration, each furnace can be set individually for the inspected index number and the number of tests, and different index numbers of cheap metal or precious metal thermocouples can be inspected/calibrated in the same furnace, and the data and results are processed and judged Automatically.

7.It supports auto-tuning of the PID of the calibration furnace, and saves the parameters Automatically after the completion of tuning.

It supports to summarise and display the running status information of multiple calibration furnaces to facilitate the management of the calibration process, and it can view the current temperature, set temperature, temperature change rate and current process of the calibration furnace.

8.Support fully Automatic calibration, after the completion of the calibration data are Automatically saved in the database, to achieve Automatic temperature control, data monitoring, data acquisition and data processing, after the completion of the calibration Automatically generate a variety of reports and save the records; support for search query through the database.

9.The information is Automatically updated according to the sensor type selected by the user.

When the factory number is entered, the system Automatically generates subsequent numbers, ensuring that the numerical order of the numbers is Automatically incremented.

10.The core technology has completely independent intellectual property rights: it is independently developed according to the relevant national calibration regulations and norms, and also has dynamic simulation calibration scenarios to provide customers with a full range of after-sales and upgrading protection.

11.The input information of the inspected transmitter supports 9 items of customised information, such as index number, grade, diameter compensation wire, etc. When testing temperature transmitter, the entry information supports upper temperature limit, lower temperature limit, accuracy, compensation wire, load resistance of current transmitter (default value is 250 ohm) and other information.
