The Sauermann CP 210-R is a transmitter designed for measuring differential pressure, air velocity, air flow, and temperature. This guide provides essential information for installation, electrical connection, and device configuration. Always ensure the device is installed by a qualified technician and that the power supply matches the specifications on the device label.
General features
The device features two 4-wire analogue outputs (0-5/10 V or 0/4-20 mA) and two relay outputs. It is protected by an IP65 housing and operates in environments from -10 to +50 degrees Celsius. It supports manual autozero via a push-button and automatic autozero on specific models (CP211/212).
Mounting
To mount the transmitter, fix the ABS plate to the wall using the supplied screws and pins (drilling diameter 6 mm). Insert the transmitter into the fixing plate at a 30-degree angle and rotate the housing clockwise until you hear a click, confirming it is securely installed.
Connections
Electrical connections must be made while the device is powered off. Verify the power supply type (24 Vac/Vdc or 100-240 Vac) on the side label before connecting. The device requires a switch and circuit breaker upstream. For 100-240 Vac models, use delayed-action fuses to handle current surges during startup.
Configuration
The output signal (voltage or current) is configured using the DIP switches on the electronic board. Refer to the configuration table in the manual to set the switches for 4-20 mA, 0-20 mA, 0-10 V, or 0-5 V outputs. Advanced configuration of units, ranges, and calculation functions can be performed via the keypad (on display models) or optional LCC-S software.
Autozero
To perform an autozero, unplug the two pressure connection tubes and press the Autozero key. On CP211 and CP212 models, unplugging the tubes is not necessary. A successful autozero is indicated by the green On light cycling off and on, and the display showing autoZ.
Maintenance
Avoid using aggressive solvents for cleaning. Protect the transmitter and probes from cleaning products containing formalin, which may be used in ducts or rooms.

Common problems
Device does not power on
Verify the power supply voltage matches the label on the side of the transmitter (24V vs 100-240V).
Incorrect output signal
Check the DIP switch configuration on the electronic board against the table provided in the manual.
Measurement drift
Perform an autozero procedure to recalibrate the sensor.
Before use
- Verify power supply type (24 Vac/Vdc or 100-240 Vac) on the device label.
- Ensure installation is performed by a qualified technician.
- Install a switch and circuit breaker upstream of the device.
- Ensure the environment is non-condensing and within -10 to +50 degrees Celsius.
- For 100-240 Vac models, use delayed-action fuses.
