用磁通门磁强计测量弱磁场,目前在一些技术先进的国家中仍被广泛采用和重视。我们根据国内工业的需要,研制出带有九个探头的磁通门磁强计,称为RC-1型弱磁场测量仪。仪器的灵敏范围为3×10~(-5)～1(Oe),对直流恒定磁场的场强,场差或梯度都可进行测量。本仪器由于带有多种不同结构的探头,因而用途广泛,在许多技术领域中可被采用。 Weak magnetic field is measured by the fluxgate magnetometer. At present, it is still widely adopted and valued in some technologically advanced countries. According to the needs of domestic industries, we have developed a fluxgate magnetometer with nine probes, called the RC-1 weak magnetic field measuring instrument. The sensitive range of the instrument is 3 × 10 ~ (-5) ~ 1 (Oe), and the field strength, field difference or gradient of DC constant magnetic field can be measured. The instrument is versatile and can be used in many technical fields due to its many different configurations of transducers.
