| You have an installed base with 4-wire devices and still want to benefit from the advantages of the Liquiline Compact CM72 2-wire transmitter (compact design, Memosens technology, use in hazardous areas, safety against operating errors)? Then this bundle is just right for you, as the RIA46 field meter powers up to two CM72 devices simultaneously. This allows you to set up two CM72 measuring points for pH, ORP, oxygen or conductivity sensors with Memosens technology in your 4-wire environment. | |
| Use the CM72 2-wire transmitter in a 4-wire environment | Thanks to its integrated loop power supply, the RIA46 4-wire field meter is able to power one or even two 2-wire transmitters of the Liquiline CM72 series. This allows you to perfectly use the compact and robust field transmitter with your 4-wire infrastructure. |
|---|---|
| Transmitter with Memosens technology | The Liquiline Compact CM72 transmitter can accommodate pH, ORP, conductivity or oxygen sensors (depending on the configuration in the ordering process). Thanks to Memosens technology and the automatic sensor recognition, you can replace worn sensors within seconds. |
| Visual indication of status diagnostics | The CM72 transmitter is equipped with a red/green LED that permanently displays the diagnostic results of the transmitter and the connected sensor, thus enabling a quick and easy status check on-site. |
| Suitable for hazardous areas | With its international explosion protection approvals, such as IECEx, ATEX, and CSA, the Liquiline Compact CM72 is suitable for hazardous area use. Therefore, it is possible to mount the CM72 in a hazardous area even if the RIA46 is installed in a non-hazardous area. |
