\n| ZLD reinjection blend<\/td>\n | 15,000\u2013100,000 \u03bcS\/cm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n A single conductivity sensor cannot span this entire range with acceptable accuracy. Most engineering teams therefore specify different sensors at different duty points: a standard 0\u201320,000 \u03bcS\/cm cell for the biological effluent, and a high-range 0\u2013200,000 \u03bcS\/cm toroidal sensor for the ZLD loop and crystallizer outlet. Shanghai ChiMay’s in-line conductivity meter product line covers both ranges with the same transmitter platform, which simplifies operator training and spare-parts management.<\/p>\n <\/span>Temperature Compensation: The Overlooked Variable<\/span><\/h2>\nConductivity is a temperature-dependent measurement. At 60 \u00b0C, a leachate sample at 25,000 \u03bcS\/cm has an apparent conductivity roughly 40\u201345 % higher than the same solution at 20 \u00b0C. Without accurate temperature compensation, a monitoring system will report an alarm that does not correspond to an actual water quality event, or worse, miss a real excursion.<\/p>\n For thermally augmented reinjection systems, this is particularly consequential. Operators who rely on uncompensated conductivity data often trigger false scale-alarm cascades, or fail to detect real conductivity spikes that indicate clay-seal degradation.<\/p>\n Shanghai ChiMay’s conductivity transmitters use a built-in PT1000 temperature element with automatic compensation to a 25 \u00b0C reference, and the compensation algorithm is configurable for solutions with non-linear temperature-conductivity profiles, which is exactly what high-TDS leachate exhibits.<\/p>\n |
