Product Description

TH8100 Magnetic Field Coil Comprehensive Calibration Device



 

1. Summary

TH8100 is a set of devices specially used to calibrate the fluxmeter coil constants of DC magnetic properties measuring instruments for soft magnetic materials. It can use the pull method or low-frequency AC Method to calibrate the coil constant NS of the magnetic permeability meter.

 

2. Features

1. Supports two calibration methods: pull-out method and low-frequency AC method.
2. Built-in precision DC current source, accuracy class 0.005.
3. Built-in precision AC current source, accuracy class 0.01.
4. Built-in precision magnetic flux meter, accuracy class 0.05.
5. Built-in precision AC voltmeter, accuracy class 0.05.
6. Equipped with standard solenoid for generating standard magnetic field.
7. Communication interfaces: RS232, USB, LAN
8. Equipped with specialized calibration software.

 

3. Application

☆ Calibration Coil Constant NS (Pull-Out Method)

1. The TH8100 host outputs precision DC current to the standard solenoid to generate a standard magnetic field H₀ (H₀=K*I, H is the coil constant of the standard solenoid, which is given by the superior measurement department.)
2. The output end of the coil under test is connected to the precision flux meter of the host computer, and adjust the zero drift of the flux meter and clear it to zero.
3. Pull the coil quickly, read the indication value Φ_H of the flux meter, and obtain the constant reference value of the coil under test through the following formula: (NS)₀=ΦH/(μ₀H₀)

 

☆ Calibration Coil Constant NS (Low-Frequency AC Method)

1. TH8100 host outputs precision AC current to standard solenoid.
2. The output end of the coil under test is connected to the precision voltmeter of the host computer.
3. Read the effective value U₂ of the voltmeter and obtain the constant reference value of the coil under test through the following formula:(NS)₀=U₂/(2πfμ₀KI)
