Specifications Teslameter ML 10 / T
Calibration - 0, maximum.
Selection of the measurement range and the type of measured induction - manual.
The normal application conditions shown in Table 1.
The limits permitted by the basic error ML 10 / T in normal conditions of use are given in Table 2.
In a - maximum value of the set measuring range;
In the x - the value of the measured quantity.
For 10 ML / T n thinning of acceptable error of the instrument additional 10 ML / T, caused by changes in ambient temperature from normal to extreme range of operating temperatures, equal to the limit of acceptable basic error for every 10 ° C change in temperature.
Limit of acceptable additional error caused by changes in the harmonic content of the measured signal from the normal value to a value of not more than 5%, equal to the limit of acceptable basic error.
Response time t 10 eslametra ML / T no more than 4s. The duration of continuous operation with a break 8:00 to restart 1hour.
Criteria for failure: the output of the basic error of the permitted limits. The mean time to repair the state of not more than 24 hours. Total average service life of at least 8 years.
Teslameter ML 10 / T restored, single function device. MTBF Teslameter at least 3000 hours, installed failure operating time of 300 hours. Specified service life ML 10 / T - not less than 4 years. Limit state criteria: technical and economic unreasonableness production repair (restoration), ie if the direct cost of repair exceeds the price of the instrument.
Operating conditions Teslameter served in Table 3.
Attention! The application of mechanical stress to the measuring parts of transducers is unacceptable! Teslameter ML 10 / T to hold in a horizontal position!
