Fluke FieldSense Technology – current and voltage measurement without metal contact

Fluke engineers have developed a technology that simultaneously provides current and voltage measurements without metal contact. Fluke gauges equipped with the patented FieldSense technology also measure the capacitive field for the voltage by means of open pliers, in addition to the magnetic field (current intensity). In terms of their functionality, they clearly stand out from other non-contact measuring methods that can only indicate the presence of magnetic fields.

How FieldSense works

FieldSense converts the existing signal with open pliers, then derives measured values for the existing voltage. First, a reference signal with known amplitude and frequency is generated, then after establishing a ground connection, a built-in sensor detects the resulting mixed signal. After digital amplification, processing and calculation, the device then derives exact measured values for voltage and frequency. The current is determined at the same time by a magnetic field.

Advantages of FieldSense over commercial electric testers and current clamps

Fluke FieldSense open pliers allow accurate measurements without current flowing through the meter. In most cases, such as hard-to-reach places like a narrow junction box, measurements can even be made one handed. The new Fluke FieldSense encoders provide electricians, electrical installers and service technicians with a single device that can significantly reduce work load.

FieldSense at reichelt: Fluke T6-600 and Fluke T6-1000

Depending on the requirements, reichelt offers two measuring devices: Fluke T6-600 and Fluke T6-1000. Both can be used without contact for voltage measurement, and measure currents up to 200A AC, as well as the existing frequency. The Fluke T6-600 (CAT III) uses FieldSense to measure voltages up to 600V and resistors up to 2k ohms, while the more powerful Fluke T6-1000 (CAT IV) measures up to 1000V and 100k ohms. In addition, the stronger model displays voltage and current simultaneously.
