WTW濁度傳感器VisoTurb系列介紹
VisoTurb?：符合 EN ISO 7027 的濁度原理的光學(xué)濁度傳感器，用于帶有超聲波清洗系統(tǒng)的水/廢水中的原位使用：
? 無(wú)需機(jī)械師的超聲波清洗
? 極低維護(hù)
? 高精度工廠校準(zhǔn)
? 操作安全性高（傳感器檢查功能）
超聲波清洗系統(tǒng)確保傳感器的低維護(hù)和持續(xù)可靠的測(cè)量操作，因此非常適合極端應(yīng)用，例如廢水處理廠。
借助 VisoTurb? 的濁度測(cè)量原理，雜散光以 90° 角進(jìn)行測(cè)量。該測(cè)量裝置適用于高達(dá) 4000 FNU 的中低濁度值。根據(jù) EN ISO 7027，紅外光用于 860 nm 波長(zhǎng)范圍內(nèi)。該波長(zhǎng)在可見范圍之外，因此可能的樣品著色通常不會(huì)造成任何干擾。
海水模型包括用于特殊介質(zhì)的傳感器：所有接液部件均由鈦和塑料制成，因此具有極強(qiáng)的耐腐蝕性。
VisoTurb?: Optical turbidity sensors according to nephelometric principle according to EN ISO 7027 for the in-situ use in water/wastewater with ultrasonic cleaning system:
? Ultrasonic cleaning without mechanics
? Extremely low-maintenance
? Highly accurate factory calibration
? High operational safety (sensor check function)
The ultrasonic cleaning system ensures the low-maintenance and continuously reliable measuring operation of the sensors, which are therefore very suited for extreme applications, such as wastewater treatment plants.
With the nephelometric measuring principle of the VisoTurb?, the stray light is measured at a 90° angle. The measuring setup is suitable for low and medium turbidity values up to 4000 FNU. According to EN ISO 7027, infrared light is used in the wavelength range of 860 nm. This wave length is outside the visible range, so that possible sample colorings generally do not cause any interference.
The sea water model includes the sensor for use in special media: All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion.
