UsageIndustrial, Laboratory

It is used to measure the applied frequency, functionally similar to vibrating reed meter. The meter incorporates light emitting diodes LEDs which are used instead of vibrating reeds to indicate applied frequency. The frequency is determined by blinking LEDs. When applied frequency matches with the frequency marked on the dial, that particular LED blinks with maximum intensity. When the applied frequency is midway between two adjacent LEDs, both LEDs blink. When the meter is switched on all the LEDs glow sequentially for a period of 1 to 1.5 seconds, thereafter it will indicate the applied frequency.
All voltage ranges are available in a single meter. Terminal screws with washers are provided only for specific voltage as per requirement & remaining two terminals are covered with insulated caps.
In case of 96mm & 144mm instruments, two sets of LEDs with the same scale range can be offered, giving two independent meters in one casing (Dual Scale). This facilitates in comparing the frequency of two voltage supplies for paralleling operation.

Features:
  • No vibrating parts.
  • No ageing effect.
  • Faster response.
  • Lighter in weight.
  • Low power consumption
  • No effect of external vibration
  • Visible in dark & from distance.

Description:

'AE' SYNCHROSCOPE is categorized into two types A) Electro-mechanical and B) Electronic.

Electro-Mechanical Type

It incorporates a POINTER and LED to indicate synchronising condition. If the generator- (II) frequency is higher or lower than that of mains- (I) the pointer rotates in clockwise or anti-clockwise direction respectively. The speed and direction of rotation depends upon difference in frequencies, which guides the operator to speed-up or slow-down the generator. Synchronising condition is determined by dark lamp method, wherein the pointer coincides with synchronising mark and the LED does not glow. The LED glows in accordance with difference in phase, frequency and amplitude of voltages. When the pointer is towards the bright LED, it indicates the antiphase condition.

Features:
  • Rugged construction.
  • Easy serviceability.
  • Wide operating voltage range.

Description:

It is used to measure the applied frequency. Vibrating Reed Frequency meters indicate the supply frequency by means of individual reeds, when rated voltage ± 20% is applied across the terminals of the meter, the particular reed, whose natural frequency of vibration coincides with the supply frequency, vibrates with full amplitude. In case the supply frequency falls midway between two reeds both the reeds vibrate, at reduced amplitude. The amplitude of vibration at the tip of reeds is high enough for a distinct indication.
The instrument can be operated at 110V, 220V, or 440V. Terminal screws with washers are provided for the selected operating voltage & remaining two terminals are covered with insulated caps.
In case of RFD96 and RFD144 instruments, two sets of reeds with the same scale range can be offered, giving two independent meters in one casing. This facilitates in comparing the frequency of two voltage supplies for paralleling operation

    UsageIndustrial Measurement

    Description:

    Maximum Demand meter is used for monitoring thermal loading in Power Distribution systems, Networks, Machines etc. It indicates maximum loading current over a period. Short-period current peaks are not registered but long overloads are registered.
    In the Maximum Demand meter the measuring current flows through the bimetal spiral which is temperature sensitive. The free end of the spiral is connected to a black measuring pointer. The moving system is activated by heat generated by the current flowing through the spiral. The instrument is provided with an additional red slave pointer with a higher friction, which makes it to remain at its maximum position, which determines the maximum average loading current. The high torque of metallic movement drags the red pointer along with the black pointer. The red pointer remains stationary at the maximum value reached. This can be reset by rotating the knob provided on front facia. To prevent false indication due to fluctuations in ambient temperature, an additional bimetallic spiral is wound in opposite direction, which is mounted on the same spindle to compensate variation in temperature from -10 to 55 degrees Centigrade.
    Frequently there is a need to measure instantaneous current simultaneously & hence moving iron movement having the same range is incorporated in the same meter.

    Features:
    • RMS measurement of maximum current.
    • Long current peaks are registered.
    • Red pointer to indicate maximum current reached.
    • Analogue Indication.
    • 20% overload capacity.
    • Instantaneous current measurement.

    Description:

    Moving coil instruments with circular scale of 240° employ a platinum taut band for suspension of moving coil assembly instead of pivot & jewel system. It is less prone to sluggishness & zero shift due to frictionless movement.
    These meters are basically used for the measurement of DC current & voltage, and can be used with built in rectifier for the measurement of AC current & voltage in the frequency range 45~65Hz. / 400Hz. The meters measure average value. It can be scaled to indicate RMS values (on request).
    These instruments are not recommended for non-sinusoidal waveforms of current & voltage. The other indications like Frequency, Power & Power factor can be offered with suitable external transducers. Speed indication is possible if used with AC tacho-generator (not in the scope of AE).
