16452A -
Keysight Technologies
The 16452A provides accurate dielectric constant and impedance measurements of liquid materials. The 16452A employs the parallel plate method, which sandwiches the liquid material between two electrodes to form a capacitor. An LCR meter or an impedance analyzer is then used to measure the capacitance created from the fixure.

Smiths Interconnect
Diamond is the best thermal conductor on earth. Combined with a low dielectric constant, it is an excellent RF dielectric material for high-frequency applications in which thermal performance is equally critical. By applying cutting-edge thin film process and extensive millimeter wave design experience, Smiths Interconnect has created a high-performance line of resistive components. The resulting products, our Diamond RF Resistives® resistors, terminations, and attenuators, are significantly reduced in size and unparalleled in average and peak power handling.

Campbell Scientific, Inc.
Campbell Scientific offers two types of leaf wetness sensors to measure the wetness of leaves: surface contact and electrical resistance. Surface contact sensors measure the electrical resistance of a water film on their surface. Electrical resistance sensors imitate the characteristics of leaves and measure the dielectric constant of their upper surfaces.

WIKA Alexander Wiegand SE & Co. KG
Optoelectronic switches are used for the detection of limit levels in liquids. The detection is widely independent of physical characteristics of the liquids such as density, dielectric constant, conductivity and refractive index. The instruments are notable for their compact design and do not feature any moving components. With a measuring tip from borosilicate or quartz glass, and robust stainless steel cases, they offer a high media compatibility.

Radiant Technologies, Inc.
The optional Chamber Task measures the Pulse Polarization response and Small Signal Capacitance of a Pyroelectric material that is being heated and/or cooled within a thermal chamber, on a hot chuck or in a furnace. From these measurements the Spontaneous Polarization Pr(q) and the Dielectric Constant er(q) are computed. These are then combined to determine the Electrical Displacement D(q) as a function of the temperature q.

16453A -
Keysight Technologies
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.

B-1020-C -
ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.

Schmid & Partner Engineering AG
The Dielectric Assessment Kit (DAK) is ideal for all applications where high-precision dielectric parameter measurements (permittivity, conductivity, loss tangent) are required, including applications in the electronic, chemical, food, and medical industries. The dielectric probes are designed for fast, precise, non-destructive, and user-friendly measurements of liquids, solids and semi-solids over the 10 MHz – 67 GHz frequency range.

McLAREN Applied Technologies
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.

Material Sensing & Instrumentation
Microwave cavity characterization complements TDR Dielectric Spectroscopy in low-loss materials, providing high-resolution permittivity and loss data at specific single frequencies. Since measurements do not change significantly with frequency in low-loss materials (Kramer-Kronig relation) cavity measurement at select frequencies provides a full characterization across the RF/microwave range.
