Product Introduction
Conductivity Sensor DDM-200 Overview
The DDM type industrial conductivity transmitter is a process instrument that indirectly measures ion concentration by measuring the conductivity value of a solution. It can continuously detect the conductivity of aqueous solutions in industrial processes online. Conductivity is an important indicator of water purity. The amount of impurities in boiler water, deionized water used in the semiconductor industry, distilled water, and industrial wastewater is determined by the conductivity method. The concentration of acids, bases, and salts in various chemical solutions, and the dissolved oxygen content in boiler water can be measured by the conductivity method. The DDM type industrial conductivity transmitter integrates the sensor, converter, and indicator into one unit, with novel design and reliable operation.
It has the following outstanding features:
1. Achieves two-wire transmission, making it easy to form a system with DDZ series instruments.
2. Modular electronic unit, shockproof and moisture-proof, reliable operation, no distributed capacitance and electromagnetic wave interference, strong anti-interference capability.
3. Equipped with an overload protection circuit. When the impurities in the measured solution seriously exceed the standard and the transmitter is overloaded, the output current does not exceed 28mA.
4. Digital local display head, intuitive and convenient.
