Loss Tangent M in Dielectric Oil
TAND220A
The measuring instrument type TAND220A complies with the international standard IEC 61620.

Fluid Level Sensor
The output of the fluid level sensor is a voltage which changes in direct proportion to the level of fluid in the probe. The difference in permittivity between air and the fluid being measured changes the capacitance between the probe's two concentric tubes as the level changes. An RS232 connection to a PC allows the user to calibrate the fluid level and thermal drift compensation. The probe is factory replaceable, allowing the electronics to be re-used should the probe become damaged or if a new probe length is required.

Dielectric Material Test Fixture
16453A
The 16453A is designed for accurate dielectric constant and loss tangent measurements on the E4991A/4291A/B. It employs the parallel plate method, which sandwiches the material between two electrodes to form a capacitor. The E4991A/4291A/B measures the capacitance created from the fixure, and option 002 firmware calculates the relative complex permittivity as described in the 16451B. Adjustment to insure parallel electrodes is required when using the 16451B. This adjustment is not required with the 16453A because the fixure has a flexible electrode that adjusts automatically to the material surface.
