Temperature, pressure, current, and voltage are all basic physical quantities that people are familiar with. In the industrial field, the quality of the product, the control of the entire process, etc., have a great influence. In these basic physical quantities, the measurement and calibration of the temperature are much more difficult. This is because the influence of the “adiabatic†and “heat transfer†of the temperature system itself is very complicated, which causes the temperature measurement calibration system to be bulky, requires a long stabilization time, and is difficult to improve accuracy. Unlike pressure systems, as long as the leakage of the pressure transmission line is guaranteed, the internal pressure and the external pressure will not affect each other. It is easy to achieve rapid pressure transmission. The stability time is only a few milliseconds and the measurement accuracy can easily reach more than a few thousand.
Let us look at a high-precision and high-stability temperature measurement system to ensure that it is "adiabatic," which means that it is impossible to completely prevent heat transfer. People usually make a large enough volume under the condition that they reach the thermal equilibrium, and think that the temperature field gradient of a small volume at the center of its internal mass is sufficiently balanced, which is one of the important reasons why the temperature calibration source is bulky. In addition, the heat transfer of a temperature system is also very complicated, often through the conduction of heat, convection and radiation to complete, it is conceivable that it suddenly is impossible to suddenly change its temperature and achieve thermal equilibrium, which is the conventional temperature calibration source To ensure a certain uniformity of temperature field, large volume, long rise and cool time, inspection, maintenance and calibration of temperature measurement system in the industrial field, time-consuming and costly and affect the reliability of the system due to multiple temperature probe installation .
In the industrial field, it is desirable to have a compact and portable temperature calibration source (a thermostatic bath) like a pressure calibrator. However, this small-sized and portable temperature calibrator must overcome the poor uniformity of the temperature field due to a reduction in size and the like. The disadvantages of poor stability, to make the temperature rise and fall within a short period of time to achieve stability, there must be close cooperation with the heating and cooling, can reduce the temperature and cooling time, cooling and heating in the miniaturized thermostatic bath will affect Temperature field uniformity, so the synthesis of various factors, to achieve ultra-small size and has a certain degree of accuracy, rapid temperature rise and fall portable temperature correction instrument, is the field of temperature measurement technology for many years to explore the development of the field application equipment.
AIKOM's ultra-miniature temperature correction instrument overcomes the technical difficulties caused by ultra-miniaturization to the maximum extent possible, enabling users to carry it to every corner of the industrial site, and implement a temperature probe for inspection, maintenance and calibration on the spot. The verification operation eliminates the need to reassemble it for reassembly and retrieval back into the laboratories for comparative calibration. The trouble of reinstalling the original system can greatly increase work efficiency, save time, improve the availability of equipment and systems, and provide on-site automatic control engineers. Excellent maintenance and calibration methods.
AIKOM series of ultra-small temperature correction instrument, a change of the traditional temperature calibration mode, its wide range of applications across the industry in every aspect of temperature measurement and calibration, and provides an adjustable analog temperature source to improve the process flow The level of control, product quality assurance, and the prevention of malfunctions and failures in the automatic protection of industrial processes provide important checks. Especially for the fixed value inspection of temperature switch, it can be done quickly, accurately and conveniently. Its application fields include: petrochemical: oil extraction, oil pipeline, petrochemical plant, oil refinery. Aikom products are currently available in the Chinese market with two series (PD-1000/PD-2000). PD-1025 is characterized by the use of semiconductor refrigeration technology, the minimum temperature can reach -25 degrees Celsius at 20 degrees Celsius, high temperature can reach 105 degrees. PD-2300 is characterized by deep groove size, 24V DC heating element, good safety and low electrostatic influence, fan cooling without external compressed air, conical tank body and heat transfer sleeve, heat The resistance is very low and the heat transfer is fast. The temperature field is specially compensated. The temperature range is from ambient temperature to 400 degrees Celsius.
The PD-2800 is characterized by its high temperature of 720 degrees Celsius, fast temperature drop, easy operation, simple operation, economy and practicality, and is particularly suitable for industrial use. However, due to the pick-type thermocouple as a tank body temperature measuring element, suitable for high temperature and low precision requirements, field dilute? PD-2600 is Aikom's latest high-precision, high stability, high temperature tank, after calibration The accuracy is plus or minus 0.3 degrees full-scale non-linear error. It can also be used to purchase a software to achieve ten-stage programmable ramping rate control for simulating and implementing actual industrial process flow. It can also input 1-5V process voltage signal to change the setting value of the tank temperature control unit to form the loop control. In short, it is a powerful computer-controlled small portable thermostatic bath, which is a representative example of excellent performance in the world.
