T4 ammeter

Also this device can be referred to: T-4, T 4.

 

T4 ammeter shield compact one limiting with separate thermocouple a thermoelectric device with a direct-reading system, and is intended to measure the current in high frequency circuits.

Dimensions - 80×80×50 mm.

Accuracy class - 2,5.

Shaking and shock resistance.

 

T4 ammeters are used as transmitters antenna ammeters in stationary and movable type.

 

Contact thermocouples, depending on the measuring range are available in two types:

- T-1 for ammeters with measuring range up to 10 A, inclusive;

- T -2 for ammeters with measuring range of current over 10 A.

 

Specifications T4:

 

Frequency - from 0,3 MHz to 7,5 MHz.

Measurement range - 0,5 A; 1 A; 2 A; 3 A; 5 A; 10 A; 20 A; 30 A; 50 A.

 

The basic error of the instruments:

- at 50 Hz - no more than ±2,5% of the nominal value of the scale;

- at frequencies from 0,3 MHz to 7,5 MHz - no more than ±5%.

 

Dials are quadratic and compressed in its initial part.

Working part of the scale - from 20% to 100%.

Operating position - vertical and horizontal.

Meter case - sprayproof.

 

Weight:

- ammeter T4 - 0,240 kg;

- thermocouple T-1 - 0,18 kg;

- thermocouple T-2 - 0,37 kg.

 

As metals forming a thermocouple type temperature sensors in T-1 and T-2 used gold-palladium alloys and platinum-iridium.

 

Operating conditions ammeters T4:

 

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

Relative humidity - 98%.

 

Ammeter T4 produced in a plastic housing for recessed mounting. T4 meters must be installed on the non-iron panels.
