Field of application
Liquiline CM42B provides precise and reliable measurement of pH, ORP, conductivity or oxygen in demanding process applications. Benefit from its intuitive local operation and configuration and use its Bluetooth interface and the SmartBlue app to get a detailed measuring point overview on your mobile devices. The Bluetooth communication is secured by a unique concept. No need to worry about intruders. Different device versions allow for flexible adaptation to all installation requirements.
The Liquiline CM42B transmitter is suitable for demanding process applications in the following industries
With its international explosion protection approvals, such as IECEx, ATEX, C/US IS Cl. I div 1 and CHN-Ex, the transmitter is suitable for hazardous areas.
Benefits
Comfortable operation and configuration: The intuitive operating concept makes commissioning and configuration on-site easy and fast. Bluetooth connection and the SmartBlue app provide an overview of the measuring point on your smartphone or tablet.
Unique security : The Bluetooth connection features a unique security concept that prevents intrusion and enables sophisticated role management of the operating staff. You profit from external and internal security.
Suitable for all process environments: The transmitter is available as stainless steel, plastic or DIN-rail version. Simply select the suitable version to integrate it into a skid, use it in hygienic environments or apply it in hazardous areas.
Increased process safety and uptime: Memosens technology provides you with safe, digital data transmission and high availability of measured values. Plug & play of pre-calibrated sensors reduces process downtime for calibration.
Seamless system integration: Liquiline CM42B offers HCF-certified HART communication which makes integration into your process control system easy and secure.
