Technical content
Space-saving transmitter for monitoring and controlling processes in industry and the environmental sector Application The CM72 transmitter can be used in all sectors and by plant manufacturers in these sectors and supports sensors with the blue Memosens plug-in head:
- pH sensors
- ORP sensors
- Contacting conductivity sensors
- Oxygen sensors Direct connection to PLC via: 4 to 20 mA Your benefits
- Space-saving installation:
- The two-wire device fits into an assembly and does not require a separate power supply.
- Minimum inventory
- Fast commissioning and maintenance:
- Thanks to its permanent configuration, the CM72 does not need to be commissioned and can start measurement immediately.
- All of the benefits of Memosens technology: lab-calibrated sensors, hot plug & play
- The status of the transmitter and the connected sensor is indicated by a red/ green LED.
- Suitable for all locations Regardless of whether your measuring point is exposed to dust, steam, rain, snow, heat or cold, the CM72 is always exactly the transmitter you need!

- Conductivity sensors Communication and data processing Communication protocols: 4 to 20 mA For configuration with the measured value and the current output turndown, select the option in the order structure when ordering. This cannot be changed at a later stage.
Memosens makes your measuring point safer and more reliable:
- Non-contact, digital signal transmission enables optimum galvanic isolation
- No contact corrosion
- Completely watertight
- Sensor can be calibrated in a lab, thus increasing the availability of the measuring point in the process
- Predictive maintenance thanks to recording of sensor data, e.g.:
- Total hours of operation
- Hours of operation with very high or very low measured values
- Hours of operation at high temperatures
- Number of steam sterilizations
- Sensor condition A0035116 2 Plug & Play with Memosens technology The status of the transmitter and the connected sensor is indicated by a red/green LED. A0036843 3 LED display Security Measured value compensation pH: Temperature Oxygen:

The lower voltage value in each case applies only to a load resistance of 0 Ohm. NOTICE The device does not have a power switch ‣ At the supply point, the power supply must be isolated from dangerous live cables by double or reinforced insulation in the case of devices with a 24 V power supply. Cable specification Cable length:
- Max. 3 m (10 ft)
- Max. 7 m (23 ft)
- Max. 15 m (49 ft) Overvoltage protection IEC 61 000-4-4 and IEC 61 000-4-5 with +/- 1 kV Performance characteristics Resolution Current output < 5 µA Repeatability → Documentation of the connected sensor Response time Current output t90 = max. 500 ms for an increase from 0 to 20 mA Tolerance Current output Typical measuring tolerances: < ±20 µA (if current value = 4 mA) < ±50 µA (for current values 4 to 20 mA) at 25 ˚C (77˚ F) each additional tolerance depending on the temperature: < 1.5 µA/K Environment Ambient temperature range –20 to 85 °C (–4 to 185 °F) The maximum ambient temperature depends on the process temperature and the transmitter's installation position. ‣ Make sure that the ambient temperature at the transmitter does not exceed 85 °C (185 °F). Example for ambient conditions in Endress+Hauser assemblies:
- for open installation (without protective cover, i.e. free convection at the transmitter), e.g. CPA442, CPA842
- for enclosed installation (with protective cover), e.g. CPA871, CPA875, CPA842 Tambient = max. 60 °C (140 °F) Tprocess = max. 100 °C (212 °F), in continuous operation Tprocess = max. 140 °C (284 °F), < 2h (for sterilization)
