Description

The Liquiline Compact CM82 is the smallest transmitter for Memosens sensors. Its slender housing measures only 11 cm long and 2 cm wide, including a connection to which you can attach your sensor directly, without a cable. Together with the sensor, it fits into most assemblies and couldn’t be easier to install. Via a uniquely secure Bluetooth connection, you can see all nearby CM82 measuring points on your tablets or smartphones and operate them conveniently from a distance.

Field of application

Liquiline Compact CM82 can be used in all industries and their utilities and supports all sensors with the blue Memosens plug-in head:

  • pH sensors
  • ORP sensors
  • Conductivity sensors
  • Oxygen sensors

The loop-powered two-wire transmitter features the following protocols and interfaces:

  • 4...20 mA
  • HART
  • Bluetooth

With its international explosion protection approvals, such as IECEx, ATEX, and CSA, the Liquiline Compact CM82 is suitable for hazardous area use.
