style="text-indent:25px">霍爾傳感器擁有體積小，重量輕，安裝方便，功耗小，頻率高、壽命長(zhǎng)、適用范圍廣等優(yōu)點(diǎn)。杭州霍爾傳感器工廠</p><p style="text-indent:25px">這里小編為您整理了如下幾點(diǎn)關(guān)于霍爾傳感器的 1、霍爾傳感器可以測(cè)量任意波形的電流和電壓，如：直流、交流、脈沖波形等，甚至對(duì)瞬態(tài)峰值的測(cè)量。副邊電流忠實(shí)地反應(yīng)原邊電流的波形。 2、原邊電路與副邊電路之間完全電隔離，絕緣電壓一般可到12KV。 3、精度高：在額定點(diǎn)精度優(yōu)于1%， 4、線性度好：優(yōu)于0.1% 5、動(dòng)態(tài)性能好：響應(yīng)時(shí)間小于１μs,追蹤速度di/dt高于50A/μs 6、工作頻帶寬：一般比較高可以到100kHz，常態(tài)工作頻率可到20kHz 7. 測(cè)量范圍寬：霍爾傳感器模塊為系統(tǒng)產(chǎn)品，電流測(cè)量可達(dá)20KA，電壓測(cè)量可達(dá)10kV。 8、過載能力強(qiáng)：當(dāng)原邊電流超負(fù)荷，模塊達(dá)到飽和，可自動(dòng)保護(hù)，即使過載電流是額定值的幾倍時(shí)，模塊也不會(huì)損壞。 9、模塊尺寸小，重量輕，易于安裝。 10、模塊的初級(jí)與次級(jí)之間的“電容效應(yīng)”是很弱的，共模電壓的各種影響通?？梢院雎?。 11、抗外磁場(chǎng)干擾能力強(qiáng)：在距模塊5-10cm處有一個(gè)兩倍于工作電流(2Ip)的電流所產(chǎn)生的磁場(chǎng)干擾而引起的誤差較小，這對(duì)大多數(shù)應(yīng)用，抗外磁場(chǎng)干擾是足夠的，但對(duì)很強(qiáng)磁場(chǎng)的干擾要采取適當(dāng)?shù)拇胧热缱龊脤?dǎo)磁或者屏蔽。杭州霍爾傳感器工廠</p></p><br
