burkert寶德8175型超聲波液位變送器,進(jìn)口BURKERT超聲波液位變送器
burkert寶德8175型超聲波液位變送器提供±15V電源，激磁電路中的晶體振蕩器產(chǎn)生400Hz的方波，經(jīng)過TDA2030功率放大器即產(chǎn)生交流激磁功率電源，通過能源環(huán)形變壓器T1從靜止的初線圈傳遞旋轉(zhuǎn)的次線圈，得到的交流電源通過軸上的整流濾波電路得到±5V的直流電源，該電源做運(yùn)算放大器AD822的工作電源；由基準(zhǔn)電源AD589與雙運(yùn)放AD822組成的高精度穩(wěn)壓電源產(chǎn)生±4.5V的精密直流電源，該電源既作為電橋電源，又作為放大器及V/F轉(zhuǎn)換器的工作電源。當(dāng)彈性軸受扭時，應(yīng)變橋檢測得到的mV的應(yīng)變信號通過儀表放大器AD620放大成1.5v±1v的強(qiáng)信號，再通過V/F轉(zhuǎn)換器LM131變換成頻率信號，通過信號環(huán)形變壓器T2從旋轉(zhuǎn)的初線圈傳遞靜止次線圈，再經(jīng)過外殼上的信號處理電路濾波、整形即可得到與彈性軸承受的扭矩成正比的頻率信號，該信號為TTL電平,既可提供給二次儀表或頻率計(jì)顯示也可直接送計(jì)算機(jī)處理。由于該旋轉(zhuǎn)變壓器動--靜環(huán)之間只有零點(diǎn)幾毫米的間隙，加之傳感器軸上部分都密封在金屬外殼之內(nèi)，形成的屏蔽，因此具有很強(qiáng)的抗干擾能力。
