DC ammeters

DC ammeters
DQ ammeters measure direct current. To measure high currents, these ammeters are used in combination with measuring shunts. Ammeters type DQ have a magnetoelectric measurement system.

Specifications:
  • Accuracy class 1.5.
  • Dimensions: 48 x 48 x 63 mm (DQ48), 72 x 72 x 63 mm (DQ72), 96 x 96 x 63 mm (DQ96), 144 x 144 x 63 mm (DQ144).
  • Measurement ranges 0-1mA, 0 (4) -20mA, 0-600mA, 0-40A.
  • The deviation of the arrow of the device is 0-90 ° (for devices of the -x series) or 0-240 ° (for devices of the -xc series).
Ammeters of the EQ type measure alternating currents, tuned to a frequency range of 16 ... 65 Hz. These devices have an electromagnetic measuring system with a moving core.

Specifications:
  • Accuracy class 1.5.
  • Dimensions: 48 x 48 x 63 mm (EQ48), 72 x 72 x 63 mm (EQ72), 96 x 96 x 63 mm (EQ96), 144 x 144 x 63 mm (EQ144).
  • Measurement range: direct connection up to 25 A for EQ48; up to 60 A for EQ72, 96, 144; through a current transformer (- / 1 A, - / 5 A) - determined by the current transformer used.
  • The deviation of the arrow of the device is 0-90 °.
Ammeters type D45-x are moving coil instruments used for DC measurements. Designed for installation on standard DIN rails, 35 × 15 mm, in accordance with the requirements of EN 50022. The devices have a magnetoelectric measuring system and replaceable scales, which can be made at the request of the customer.

Specifications:
  • Accuracy class 1.5.
  • Overall dimensions 85 × 45 × 63 mm.
  • Measurement ranges 0-1mA, 0 (4) -20mA, 0-600mA, 0-40A.
  • The deviation of the arrow of the device is 0-90 °.
Ammeters type E45-x - devices with a moving core, designed to measure the effective values ​​of the current strength. The devices are mounted on standard DIN rails, 35 × 15 mm, in accordance with the requirements of EN 50022.

Specifications:
  • Accuracy class 1.5.
  • Overall dimensions: 85 × 45 × 63 mm.
  • Measurement range: direct connection up to 25 A; through a current transformer (- / 1 A, - / 5 A) - determined by the current transformer used.
  • The deviation of the arrow of the device is 0-90 °.
Ammeters type BQ are designed for thermal monitoring of power cables, transformers, etc. Due to their design, ammeters of the BQ type do not react to short-term current changes, but record its steady-state value.

Specifications:
  • Accuracy class 3
  • Measuring range via current transformer (- / 1 A, - / 5 A): determined by the current transformer used.
Ammeters type BEQ are designed to indicate the thermal load of power cables, transformers, etc. The measuring mechanisms of the EQ and BQ instruments are combined in one housing. A thermal measuring system with a bimetallic spring and an electromagnetic measuring system with a moving core are used to measure the maximum and instantaneous values ​​of the measured value.

Specifications:
  • Accuracy class 3.
  • Measuring range via current transformer (- / 1 A, - / 5 A): determined by the current transformer used.
Ammeters of the VDQ96-sw type are designed to measure effective current values. They are used in the equipment of power plants, distribution and transformer substations.

Specifications:
  • Accuracy class 1.5.
  • Overall dimensions 96 × 96 × 63 mm.
  • Measurement range: through a current transformer (- / 1 A, - / 5 A) - determined by the current transformer used.
  • The deviation of the arrow of the device is 0-90 °.
