IET GENRAD 1620-A CAPACITY BRIDGE
The IET GenRad 1620-A Capacity Bridge is a stand-alone unit of the 1615-A Capacitance Bridge with suitable oscillator and zero detector for measurements at 11 frequencies between 50 Hz and 10 kHz. For applications requiring different or higher frequencies, up to 100 kHz, the 1615-A Bridge can be supplied separately and the oscillator and detector selected to suit your needs.
APPLICATIONS IET GENRAD 1620-A CAPACITY BRIDGE
- Accurate and accurate measurements of capacity and dissipation factor
- Measurement of the circuit capacity
- Dielectric measurements
- Comparison of capacity standards difference in size by as much as 1000:1
- 10-5 pF to 11.1 μF, 2 or 3 clamps
- 0.01% accuracy, 1 ppm resolution
- Lever balance, in-line readout
- Reads dissipation factor or conduction
1615-A CAPACITY BRIDGE
The 1615-A Capacitance Bridge brings the measurement of the capacitance, the comparison of the standard, and the measurement of the dielectric properties.
A special degree of accuracy, precision, range and convenience. The high accuracy is achieved by the use of precisely wound transformer arms and very stable.
Standards manufactured from Invar and hermetically sealed in dry nitrogen. For the calibration of these standards can be compared.
TWO OR THREE CLAMP CONNECTION
Accurate three-time measurements can be made even in the presence of earthing capacities as large as 1 μF, as one might encounter with the unknown connected by long cables. The bridge has the necessary internal shielding to ground one terminal of the unknown capacitor directly, so true two- and three-time measurements can both be made over the entire capacitance range.
ELEMENTARY DIAGRAM
The elementary scheme 1615-A is also clearly delineated on the front panel of the bridge. Changes in connections and terrains are indicated automatically if you switch the bridge clamps for different measuring conditions. Range Extension up to 11.1 F – With the Range Extension Capacitor 1615-P1, the 1615-A will measure up to a maximum of 11,11110 F. This capacitor is connected to the bridge terminal blocks front panel and can be adjusted for calibration according to the bridge standards.
