Industrial electric detonator RF impedance measurement
1 Scope
This standard specifies the principles of industrial electric detonators RF impedance measurement, instruments, equipment and devices, test conditions, and test sample preparation
program.
This standard applies to the determination of industrial electric detonators to 1MHz ~ 1300MHz frequency impedance.
Principle 2
RF impedance analyzer, through the extension of the cable, a short-circuit (0Ω), breaking (0S) and three standard 50Ω terminal 1MHz ~
1300MHz frequency range automatic calibration, and then on the calibration frequencies of industrial electric detonator RF impedance measurements, according to public
Formula (1) shows the direct RF impedance of the resistance component and reactance component values. Measurement system block diagram shown in Figure 1.
Z = R jX (1)
Where.
Numerical Z --- RF impedance in ohms (Ω);
Numerical R --- RF impedance of the resistance component in ohms (Ω);
j --- -1;
X --- RF impedance reactance component value in ohms (Ω).

3 apparatus, equipment and apparatus
RF Impedance Analyzer. standard terminal should be equipped with extension cable and short-circuit (0Ω), breaking (0S) and 50Ω of three calibration; the instrument
Operating frequency of 1MHz ~ 1300MHz, the measured current is not greater than 500μΑ, extending the length of the cable should be suitable for industrial electric detonator RF resistance
Security measure antibody; the extension cable terminal should be adapted to connect with the industrial electric detonator.
4 Test conditions
4.1 Environmental conditions
Determination of industrial electric detonators RF impedance of the ambient temperature should be 16 ℃ ~ 32 ℃, relative humidity should not exceed 75%. During the measurements,
Record the actual environmental conditions.
