Use and application:

Voltage, AC current, voltage, frequency, power factor, phase sequence, power, synchronous indication and other non-electrical measurement.Many used in maritime ships, rail transit , Chemical explosion-proof, low-voltage equipment, construction equipment, generating units, machinery and equipment industries AC and DC power transmission and distribution systems, power control panel and other electrical equipment on the role of electrical measurement and non-electrical measurement is applicable General requirements in the environmental conditions are more general in the high-end instruments.

Standards and certification:

Elite instrumentation electrical instrument series pointer is in accordance with GB / T7676-1998, Digital instrument is in accordance with GB / T22264-2008Standard production, the safety performance in accordance with GB4793and IEC61010Standard production. The scale of the dial and pointer design in line with Germany DIN43790with DIN 43802Standard. Meter shape and hole size in accordance with GB / T1242with IEC 61554Standard production. Elite instrumentation company all products through the country CE Certification, and access IS0;Certification.

Board table shell:

JY series The base is flame retardant TBT Made of plastic, Vicat temperature 130 ° C. shell By flame retardant ABS Made of plastic, Vicat temperature 85 ° C.

Temperature-induced change:

Reference temperature is 23 ° C ± 2 ° C. 13 ° C to 23 ° Cas well as 23 ° C to 33 ° CTemperature range, the temperature change is not allowed to change the level of index ± 100%.

Installation location and installation:

Unless otherwise specified, the instrument is normally mounted in a vertical position Other installation positions such as horizontal installation and tilting installation can be made according to customer requirements The corresponding accuracy level is valid only for the specified installation position. 90 °And wide angle 250 °, Two kinds of indication angle.

Anti-vibration and impact:

Anti-vibration : meets the IEC 60068-2-6Standard; Sweep range: 10-55-10Hz ; Displacement amplitude: ± 0.15mm, ± 0.3mm.

Sweep Cycles: 5Times; Sweep rate: 10ct / min ; Maximum acceleration: 147 m / s2 (15g) , 490 m / s2 (50g) .

Acceleration RMS: 6.06g; Vibration time: 15 min . Anti-mechanical shock, consistent IEC60068-2-27standard.

Accuracy class:

JY series Pointer instrumentation :AC-DC voltmeter and ammeter in the 1.5Level or 2.5Level, power meter for 2.5Level, the frequency table 2.5Level, power factor meter for 2.5level.

Overload ammeter:

The overload factor is normal 1Times and 2Times the overload factor, can be customized to user requirements 1Times, 2Times, 3Etc. Its role is to indicate the approximate instantaneous value of the overload current, such as the start-up current when the motor starts.

External Current Shunt:

DC ammeter shunt voltage drop specifications attached 150mV , 100mV , 75 mV , 60mV with 50mV Etc. Can be customized by the user requirements. Instrument and shunt connection wire resistance requirements 15~25mΩ, To ensure instrument accuracy.

Surface Dial:

surface Dial: aluminum alloy, white paint, black ink printing or laser printing printing. Can be customized according to customer sample dial (can be customized a variety of colors overprint.) Luminometer dial with PC board.

Zero adjuster:

In addition to no mechanical zero reading meter ,All other instruments have a pre-zero adjuster for adjusting the instrument mechanical zero.

Advantages of the product (replaceable dial):

JY series As long as the transformer secondary current is the same, you can replace the dial, replace the accuracy of the same; DC ammeter as long as the shunt output of the same electrical signal or Instrument input signal the same, different specifications can replace the dial, the replacement, the accuracy of the same.
