Toroidal Core Checker "TCC Series"

Toroidal Core Checker "TCC Series"

Applicable to incoming inspections and manufacturing sites! Estimation of μ and L can be done regardless of core size.

The "TCC Series" is a toroidal core checker that allows for the evaluation of the quality of a toroidal core (core alone) without winding. The pass/fail judgment threshold can be set arbitrarily. A buzzer will notify you if the measurement is below the threshold. Additionally, it is possible to estimate the inductance (L) at a specified number of windings by comparing it with a reference core. Please use it for measuring high permeability materials such as nanocrystal, permalloy, and ferrite. 【Features】 ■ Allows for the evaluation of the quality of a toroidal core (core alone) without winding ■ The pass/fail judgment threshold can be set arbitrarily ■ Enables estimation of permeability (μ) by comparison with a reference core ■ Allows estimation of μ and L regardless of core size ■ Suitable for measuring high permeability materials such as nanocrystal, permalloy, and ferrite *For more details, please refer to the PDF document or feel free to contact us.
