Ammeter T23M

Also this device can be called: T-23M, T 23M, T23-M, T-23-M, T 23 M.


T23M ammeter designed to measure current in AC circuits frequencies from 1 MHz to 30 MHz. Used with an additional device P23.

Dimensions - 60×60 mm.

Shaking and vibration resistance.


Specifications of ammeters T23M:


Measuring ranges - 1 A to 3 A, 1 A to 5 A 2 A to 10 A, 5 A to 20 A, 10 A to 30 A.


Basic accuracy:

- in the nominal frequency range from 1 MHz to 10 MHz - ±5%;

- in the extended frequency range from 10 MHz to 30 MHz - ±7%.


Settling time of the mobile device - no more than 6 seconds.

Scale ammeter T23M - uneven.

Operating position - horizontal, vertical.

Operating position of additional devices - any.


Variation in the ammeter T23M:

- caused by ambient temperature deviation from the normal - no more than ±2,5% for every 10°;

- under the influence of an external magnetic field of 400 A/m, when installing the device on a ferromagnetic shield or influenced placed back to back with him of the same device - no more than ±1%.


Minimum probability of failure of the device for 500 hours of testing - 0,7.

Confidence probability of failure of the device for 500 hours of testing - 0,8.

Diameter recessed portion meter - 57 mm.

Weight of ammeter without additional devices - 0,15 kg.

Weight of additional device - 0,35 kg.


Meter of ammeter T23M structurally designed in a plastic housing flush mounting. System unit - magneto. Measuring mechanism has within the framework magnet and mount the movable part on extensions. Measuring circuit ammeter T23M protected by metal screens.


Operating conditions T23M:


The ambient air temperature - from -40° C to +60° C.

Relative humidity at +35° C - 95±3%.


Additional P23 device, consisting of a high-frequency transformer and vacuum thermocouple, decorated in a metal casing, serving an electromagnetic shield that eliminates the influence of external fields.
