聯(lián)系我時(shí)，請(qǐng)告知來(lái)自 儀表網(wǎng)產(chǎn)品描述 非接觸式連續(xù)測(cè)量物位和流量的超聲波探頭與FMU90/FMU95變送器配套使用
優(yōu)點(diǎn)
非接觸式測(cè)量方法; 降低了維護(hù)需要
集成溫度探頭用于校正超聲波運(yùn)行時(shí)間。即便處于溫度變化的環(huán)境之中，也可得到準(zhǔn)確的測(cè)量結(jié)果.
FMU90 /FMU95變送器能自動(dòng)識(shí)別探頭類型，因此調(diào)試十分簡(jiǎn)單
探頭和變送器能分離安裝，最長(zhǎng)間距達(dá)300m
探頭可與變送器分離進(jìn)行安裝，能適應(yīng)惡劣的外部工作環(huán)境
探頭的自清洗功能有效地降低了粘附現(xiàn)象發(fā)生的可能性
抗侵蝕，防水型 (IP68)
通過(guò)粉塵防爆(Dust-Ex)認(rèn)證和氣體防爆(Gas-Ex)認(rèn)證(ATEX, FM, CSA, TIIS)
