Product Details

AH11A standard capacitor

Each AH11A has a molten silicon disk as its basic element, used to form a capacitor bank, and the values inside are calculated using binary addition

The right. The factory selects appropriate capacitors from them, so that AH11A can provide a wide range and very accurate set capacitance value. final value

The adjustment is achieved by making small temperature adjustments to the temperature control device. This method can avoid the inconvenience caused by adjusting capacitors separately

Instability of connectivity. Therefore, the dielectric of AH11A is very close to 100% solid molten silicon.

The molten silicon disk is sealed in a temperature controlled copper box that is well insulated from the outside of AH11A. The temperature of this copper box is measured by two precise temperature sensors

Monitor the device and connect it to two completely independent control circuits. The average output voltage generated by these two circuits is used to control the copper box

The temperature. The differences in these output voltages can be selected to be displayed on the front panel of the AH1100 chassis. As time goes by, its difference

The value will gradually approach zero. The smaller the difference, the higher the trust in the stability of the temperature control device.

Each AH11A is equipped with temperature measurement and control circuits internally. The connection between AH11A and AH1100 has 3 connectors: 2

One BNC and one 16 pin connector.

Calibrate a certain range

For applications with narrow measurement ranges, one or more standard capacitors within the application range can be selected. This is determined by the application

The selection of standard capacitance values can greatly increase confidence in measurement accuracy within this range. An example is the calibration of a fuel gauge, which represents

The capacitance values of "empty" and "full" are useful calibration points because they represent the limits of the testing range.

Calibrate a set of capacitance values

Having a set of standard capacitors equal to the nominal value for a clearly defined set of value measurement applications can greatly increase the ability to perform such tests

Confidence in accuracy. Especially for batch applications, this approach can achieve a predetermined accuracy through testing with low-cost capacitance meters.

The ability of AH11A to be set to any value enables this strategy to achieve unprecedented accuracy.

Deviation measurement

The ability to accurately set the AH11A value can also be used as a reference standard to compare with unknown capacitors. Adopting this method

Measuring the difference in capacitance may result in faster and more accurate results simultaneously.

Linearity measurement

Only using a combination of 4 standard capacitors, such as 1, 2, 4, 5, or similar combinations, is allowed within the range of 1 to 10

Perform high-precision linearity calibration. For example, standard capacitor combinations of 10, 20, 40, and 50pF can be used in parallel to create combinations of 10-120pF

The capacitance value between any multiples of 10. Adding another value, such as a combination of 1, 1, 2, 4, and 5, can form an internal one

The sequence value used for self checking the consistency.
