The thermal calibrator is a transformer calibrator developed on the basis of detailed analysis of the mathematical model of the transformer. Transformer calibration does not require current power supplies, large standard transformers and load boxes. Just carry a thermal calibrator to measure the ratio and angle difference of the current transformer according to the national standard, and any percentage difference and angle difference between 1-20% current; this can directly measure the current transformer and voltage The transformation ratio of the transformer; the ratio difference and angle difference of the voltage transformer can be qualitatively measured; the actual secondary load of the current and voltage transformer can be measured on site, and the verification is particularly convenient.

The main features of thermal calibrator:

1. Measure the secondary load of the current and voltage transformers on site, and measure the ratio difference and angle difference of the current transformers under the load.

2. Measure the ratio difference and angle difference of the current transformer according to the national standard, and measure the 0.2S and 0.5s current transformers on site; in one measurement process, the standard error of the current transformers under the upper limit load and the lower limit load can be tested at the same time .

3. The transformation ratio of the current transformer or the voltage transformer can be measured without identification, the measurement is accurate and fast, and the stability is good, and no additional current rise or boost source is required.

4. Large-screen LCD display, full Chinese prompts, automatic measurement, and the entire instrument operation process is simple; this instrument is small in size and easy to carry. Only a few people can quickly complete the measurement work.

5. The voltage transformer can be measured qualitatively: during measurement, the instrument can measure the primary voltage and secondary induced voltage by adding a certain power frequency voltage to the primary side of the voltage transformer, and obtain the transformation ratio and polarity of the voltage transformer under this voltage. .

6. Various measurement data can be stored and printed, and the setting parameters can be saved when the power is turned off.

Thermal calibrators are mainly used to calibrate the test data of various temperature components (thermocouples, platinum resistance thermometers, thermometers), temperature transmitters (sensors), temperature switches and temperature instruments. The design principle of the field application dry trap temperature calibration furnace is easy to carry, easy to use, fast and reliable temperature calibration. Widely used in machinery, chemical industry, food, medicine and other industries.

The instrument adopts an integrated design, which is firm, compact, lightweight and easy to operate. The box-type protection is resistant to electromagnetic and strong magnetic field interference. The instrument can be used in instrument workshops, measurement rooms and calibration laboratories. High reliability electronic components are selected, and the temperature control of the whole machine is stable. All required displays or operations are displayed or operated through a high-brightness large-screen LCD touch display and LED backlight. Test operation is simple, intuitive and easy to understand.

The thermal calibrator adopts a high-performance intelligent thermostat with LCD touch screen. On the basis of a number of classic technologies, an ultra-thin intelligent temperature controller with functions such as measurement, display, control, and alarm has been developed and launched, which can realize the measurement and control of temperature parameters.
