System Architecture & Signal Flow
The CLM253-CD0005 operates as a 4-wire transmitter in a standard liquid analysis loop:
- Sensor Input: Conductive or inductive conductivity sensor (E+H CLS or CLs series) connected via M12 or terminal block
- Signal Conditioning: Internal microprocessor applies temperature compensation and range scaling
- Primary Output: 4–20 mA analog signal proportional to measured conductivity/resistivity value
- Digital Communication: HART overlay on the 4–20 mA loop for remote parameterization and diagnostics
- Relay Outputs: Configurable limit/alarm relays for DCS/PLC integration or local alarm activation
- Display: Local LCD readout with keypad for on-site configuration and calibration
Compatible with Endress+Hauser Fieldgate, FieldCare, and third-party HART asset management systems.

Technical FAQ
Q: Is the CLM253-CD0005 compatible with inductive (toroidal) sensors?
A: Yes. The CLM253 platform supports both conductive (2-electrode) and inductive (toroidal) conductivity sensors. Verify sensor model compatibility with E+H’s Applicator tool or contact us for confirmation.
Q: Can this transmitter be used in ATEX hazardous areas?
A: The CD0005 ordering code designates a standard (non-Ex) version. ATEX/IECEx variants are available under different order codes. Contact us if you require an Ex-rated version.
Q: What is the conductivity measurement range?
A: The CLM253 covers 0.01 µS/cm to 500 mS/cm depending on the connected sensor cell constant. This spans ultrapure water through concentrated process media.
Q: Does the unit ship with a calibration certificate?
A: Yes. Every unit includes the original E+H factory calibration certificate. On-site recalibration using NIST-traceable conductivity standards is supported.
Q: What is your warranty policy?
A: All units carry a 12-month warranty against manufacturing defects. Units that fail functional verification are replaced or fully refunded.
Q: Can you supply multiple units for a plant-wide project?
A: Yes. We handle project quantities from 1 to 100+ units. Volume pricing and consolidated shipping are available — submit your BOM to [email protected].
