Yokogawa CP450C-A-ANSI Conductivity/Resistivity Converter
This converter handles conductivity and resistivity measurements with remarkable stability, even in harsh industrial conditions. We’ve seen it perform consistently in chemical plants where corrosive substances are common, as well as in power stations monitoring cooling water systems. The dual power supply option (100-240V AC or 12-24V DC) gives flexibility for different installation environments.

We’ve installed these in both indoor control rooms and outdoor processing areas without issues. The stainless steel housing handles coastal humidity well – one customer in Singapore uses them near seawater intake systems. The HART communication allows technicians to adjust calibration remotely through their DCS systems, which cuts down on maintenance trips.
For similar applications, we often pair this with Yokogawa’s SC450 sensors or older SC200 series transmitters when customers need continuity with existing systems. The conduit adapters (G1/2, 1/2NPT, M20) make integration with different piping systems straightforward.

Our team keeps standard configurations in stock across 6 countries, with 16 regional warehouses. If you need a specific configuration with particular sensor pairing or special cable glands, we can typically get it ready within 5-7 business days. Every unit comes with our 12-month quality guarantee – we had one batch installed in a sulfuric acid plant in Turkey that’s still going strong after 18 months without maintenance.
