Technical characteristics
Transducer measuring calorimetric EE4.681.465
EE4.681.465 transducer measuring calorimetric is a piece of coaxial line with standard coaxial connector type III according to GOST 13317-73, absorbing element cylindrical shape with a matching screen, thermoelectric module, "the comparison body" radiator and fan motor on the basis of UAD-12F.
The design of the measuring transducer EE4.681.465:
The center conductor of the coaxial path is a thin-walled stainless steel tube to avoid thermal effects of the environment on the absorber. To reduce the loss of microwave tube is covered with copper and silver. Absorbing element is a thin film resistor on a thermally conductive (beryllium) ceramics, has an electrical contact with the center conductor - due to a tight fit, the other end is soldered to the copper screen with a matching silver plated. Matching screen has a step change in diameter, which provides the coordination of the absorbing element in the whole frequency range.
Calorimetric module configured as a disk with a hole and positioned so that the 'hot' junctions have thermal contact with the outer surface of the screen terminating in soldering the absorbent element, and "cold" junctions - a "body comparison". By the conclusion of the thermoelectric module soldered wire connection cable. Internal and external screens are designed to protect the thermoelectric module from accidental x external thermal influences.
The external screen reinforced ribs forming the radiator screen.
Through the radiator, fan cooled, inverter power dissipation increases to 20 W.
Dimensions - 187×150×84 mm.
Weight - 2 kg.
Electrical scheme EE4.681.465:
Microwave signal is fed to the absorber RI and is scattered as it heats. The temperature difference between the absorbent element and the transducer housing, the input power is proportional to, registers Tn one thermoelectric module. Formed at the module output Tn1 thermopower with a cable supplied to pins 1 and 5 sockets Sh3 mounted on its end. Through the divider R2 and R3 transmitter sensitivity is reduced to the nominal value, that has normal th work of the measuring unit.
The converter has a fan, by which the intensity of heat removal from the converter housing and thus is achieved power dissipation of 20 watts. In an asynchronous fan motor M1.Capacitors C1 - C4 are used to start the motor from a single phase supply.
The kit converter EE4.681.465 includes:
- transition coaxial 5,433,020 - 16×7, 7×3 mm;
- transition coaxial 5,433,021 - 10×4,34; 7×3 mm;
- transition waveguide-coaxial 5,433,022 - 23×10, 7×3 mm;
- transition waveguide-coaxial 5,433,023 - 16×8, 7×3 mm;
- bolt installation 8.920.459-02;
- bolt 8.920.460-02;
- nut 8.930.366-01.
The manufacturer provides a guarantee of compliance converters 4.681.465 all technical requirements if the consumer terms and conditions of use, storage and transportation, installed documentation manuals.
