Mini Analog Panel Meter Ammeter / Voltmeter ( 91C4)
Uses and applications:
This series of meters is a direct imitation of power measurement display instruments, measuring DC current and voltage, AC current and voltage, frequency, power factor, phase sequence, power, synchronization instructions and other non-power measurements. It has been widely used in a variety of AC and DC transmission and distribution systems, power control panels and other electrical devices, in the industries of maritime shipping, rail transport, chemical flameproof, low voltage equipment, construction equipment, generators, machinery equipment, etc. Being able to make electrical measurement and non-power measurement, it is a high-end instrument applied in general environmental conditions.
Standards and certifications:
The Jingying series of pointer meter is produced on the standard of GB/T7676-1998, and the digital meter is on the standard of GB/T22264-2008. Its safety performance is on the standard of GB4793 and IEC61010. The dial scale line and the pointer is designed to meet the German standards of DIN43790 and DIN43802. The shape and hole size of the meter is on the standards of GB/T1242 and IEC61554. All the products of Jingying meters Company have gone through the national CE certification, and have got ISO: 9001 certification.
The outer casing of the panel meter:
The base of the series of JY meters is made of TBT flame-retardant plastic, and its vicat temperature is 130. The outer shell is made of ABS flame-retardant plastic, and its vicat temperature is 85.
Changes caused by the temperature:
Temperature range for reference: 23 be out of the range of the level index ± 100%.
Unless specified, the meter is usually installed in a vertical position. Other installation positions such as horizontal and inclined position can be installed according to the customer's requirements. The corresponding level of accuracy is only valid to the regulated installation position. The meter has two kinds of instruction angles: Right angle 90and wide angle 250.
Anti-vibration and anti-shock:
Anti-vibration: Complies with the standard of IEC60068-2-6; Frequency sweep range: 10-55-10Hz; Displacement amplitude: ± 0.15mm, ± 0.3mm; Frequency sweep cycles: 5 times; Sweep rate: 10ct/min; Maximum acceleration: 147m/s2(15g), 490m/s2(50g); RMS acceleration: 6.06g; Vibration time: 15 min. Anti mechanical shock: Complies with the standard of IEC60068-2-27.
The JY series of pointer meter: AC and DC voltmeter and ammeter to the level of 1.5 or 2.5, power meter to the level of 2.5, frequency meter to the level of 2.5, and power factor meter to the level of 2.5.
Extrinsic current shunt:
The voltage specifications of the extrinsic current shunt of DC ammeters are 150mV, 100mV, 75mV, 60mV and 50mV, which can be customized. The resistance of the conducting wire connecting the meter and the current shunt should within the range of 1525mΩ , to ensure the accuracy of the meter.
The surface of the dial:
The surface of the dial uses aluminum alloy, white paint, black ink printing or laser printing. The dial can be customized according to the customer's sample dials (overprint colors can be customized). The luminous dial uses the PC panel.
