Preserve the full code through enquiry, quotation and order

For a multi-channel analysis point, a small difference in input modules or output allocation can affect several signals at once. Keep the +AA suffix in the requested reference and ask the supplier to reproduce the complete code on its offer. Do not assume a listing without the suffix defines an equivalent delivery. Send CM444-AAM41A3F010BAA+AA exactly as specified rather than shortening the enquiry to “CM444.” This gives procurement and engineering a common reference for checking the offered item.

What the Liquiline CM444 platform offers

The manufacturer describes CM444 as a modular multi-channel field transmitter for digital Memosens sensors. Depending on the connected sensor and supported configuration, the platform covers parameters including pH, ORP, conductivity, oxygen and turbidity. The controller receives the sensor signal; the selected probe and installation determine the application-specific measurement requirements.

These are CM444 family capabilities, not a character-by-character decoding of CM444-AAM41A3F010BAA+AA. Confirm the supplied unit's channel count, power specification, relay arrangement, communication and approvals from the order confirmation and device documentation.

Three checks before scheduling installation

Check the sensor side. Provide the complete probe codes and cable requirements. For multiple planned measuring points, confirm that the offered unit supports all intended sensors and the required parameters. Multiple current outputs are not proof of multiple installed sensor inputs.

Check the control-system side. Record the required current outputs, relay duties and communication protocol. Identify which measured value must reach which system input. A transmitter family offering several protocols does not mean every shipped unit includes them all.

Check the delivery boundary. List transmitter, sensors, cables, mounting and documentation separately. For a skid project, identify the item needed first for panel work and the items needed later for commissioning. Ask for available quantity and dispatch timing against the exact configuration.

The +AA suffix is part of the purchasing reference

This enquiry is for CM444-AAM41A3F010BAA+AA. Preserve the entire string when requesting stock or placing an order. The meaning and supplied scope of additional options must be confirmed against the manufacturer’s configured order documentation; this article does not assign an unverified meaning to +AA.

CM444-AAM41A3F010BAA+AA buying questions

Does every CM444 include four sensor inputs?

The platform supports up to four Memosens digital inputs; actual channel availability depends on the ordered and installed configuration. Verify the installed configuration of the exact unit offered.

Are probes and cables included?

Only if they are expressly included in the quotation. The transmitter's complete order code should not be treated as a complete measuring-point bill of materials.

Can I compare a shorter CM444 code?

Request a configuration comparison first. Match power, sensors, outputs, communication, housing and required documentation.

What should a CM444 stock enquiry include?
