Replaceable scale for ammeter EQ144 - 80A E144 80A 004805396

Exchangeable scales for ammeters – precision current measurements

An exchangeable scale for the EQ144 ammeter with a range of 80A, manufactured by ETI POLAM, is an essential element for correctly reading the current intensity in measurement systems. It is dedicated to ammeters of the EQ144 series and allows for their calibration or replacement of a damaged element. This ensures continuity and accuracy of measurements in electrical installations.

Characteristics and application

ETI POLAM exchangeable scales are characterized by high precision and resistance to environmental conditions. They are intended for use in magnetoelectric measuring instruments, where they serve to indicate the value of electric current intensity. The use of a scale with a range of 80A allows for measuring currents in circuits with a higher load, which is important in industrial installations, workshops and laboratories. The exchangeable scale allows for quick adaptation of the ammeter to different measurement ranges without the need to replace the entire device.

Construction and user features

The scale has a frame with dimensions of 96x96 mm, which ensures its compatibility with most ammeters of the EQ144 series. The maximum pointer deflection angle is 90 degrees. Made of high-quality materials, it guarantees stable indications and long-term reliability. The initial and final values of the scale are 0A and 80A, respectively, providing a clear and precise reading of measurements. The scale design minimizes the influence of external electromagnetic fields on the measurement result, which is particularly important in environments with high interference. Additionally, the scale is characterized by high resistance to vibrations and mechanical shocks, which increases its durability in harsh working conditions.
