Ammeter T25M (T 25 M, T-25-M, T25 M, T25-M, T 25M, T-25M)
 
T25M ammeter designed to measure AC, 50 Hz and in an extended range of frequencies from 30 Hz to 7.5 MHz.
Dimensions - 60h60h56mm.
Accuracy class - 2.5.
Resistant to shaking, vibration.
 
Technical characteristics of the instrument ammeters T25M:
 
Devices can be made to work in a moderate (normal execution) and tropical climates (tropical version).
In the tropical version instruments designated T25MT.
Devices such as T25M and T25MT used at an ambient temperature of -40 º C to +60 ° C and relative humidity up to 95% (at 35 ° C).
In terms of resistance to mechanical stress device ammeter T25M refers to shaking and vibration.
Measuring range - 1A, 2A, 3A, 10A.
The main error of the instrument ammeter T25M - ≤ ± 2,5%.
Settling time moving part - ≤ 4s.
Working position of the device ammeter T25M - horizontal and vertical.
Working position of the thermometer - the horizontal.
The scale of the instrument ammeter T25M - irregular.
The change of reading due to the change of ambient temperature of 20 º C ± 5 ° C (class H) does not exceed ± 2% for every 10 degrees, under the influence of a uniform magnetic field VDC 400A / m and a uniform magnetic field of alternating current frequency 50Hz tension 400A / m and when the frequency from 50Hz to anyone within the extended frequency range - does not exceed ± 2,5% of full scale measurement range, and under the influence of the nearby of the same device, or install it on a ferromagnetic shield - does not exceed ± 0,5%.
Weight of device without ammeter T25M converter - no more than 0.15 kg, with a thermocouple - no more than 0.25 kg.
Devices are designed in a plastic dust-and splash-proof enclosure for flush mounting.
Mounting of thermocouple ammeter device T25M is produced by two M3 screws.Thermoelectric device measuring mechanism system with a separate thermocouple.
The minimum probability of failure-free operation of devices for 500 hours of testing not less than 0.7 at a confidence level of 0.9.
