A small yet powerful transmitter has been added to Endress+Hauser’s analytical portfolio. The Liquiline Compact CM82 is perfect for analytical measuring points where installation space is extremely restricted but functionality, flexibility and ease of use are important.
Although it is only 11 cm long and 2 cm wide, the CM82 is a fully fledged multiparameter transmitter for pH, ORP, conductivity and oxygen Memosens sensors. Memosens technology ensures reliable data transmission and removes the need for calibration in the field: the sensors are pre-calibrated and can be swapped in and out of the process in seconds. Sensors of the same type can be used for all your measuring points.
Secure Bluetooth transmission
The CM82 can be operated via Bluetooth from any iOS or Android device. Just use Endress+Hauser’s free SmartBlue app to see all the measuring points within the Bluetooth range of your tablet or smartphone. There’s no need to worry about security: the Bluetooth connection is protected with the same technology that guards German identity cards against unauthorized access by third parties.
As a loop-powered two-wire device, the CM82 can be connected directly to a PLC, which also serves as the power supply, thus eliminating the need for a power cable. You don’t need a cable for the sensor connection either, since the sensor is plugged directly into the transmitter. Together with the sensor, it fits into almost every assembly.
Retain your data and settings
If a CM82 measuring point is parameterised, all settings are saved in the device. In the case of a sensor exchange, the transmitter – and thus the measuring point configuration – always stays on-site. A new parameterisation is not necessary. In addition, the CM82 reads all sensor and calibration data stored in the head of a Memosens sensor. As a result, the sensor is automatically detected within seconds and the measurement is immediately ready for use after a sensor change.
Where can I use the CM82?
The transmitter is ideal if you have limited space available for installation, you are already using 4 – 20 mA / HART and you would like to be able to operate the measuring point easily via tablet or smartphone rather than using a display at the measuring point. The transmitter comes with Class IP67 and IP68 equipment protection and can therefore be used indoors and outdoors in all conditions, such as humidity, heat or cold.
