Transducer range error on ACQUITY I-Class and ACQUITY UPLC BSM - WKB6508

Article number: 6508

SYMPTOMS

  • Error: Pump B: Transducer range error
  • Pressure fluctuations up to 26 000 psi. These are random and not synched with the pump movements.

ENVIRONMENT

  • ACQUITY UPLC I-Class Binary Solvent Manager
  • ACQUITY UPLC BSM

CAUSE

Faulty transducer

FIX or WORKAROUND

  1. Power off pump.
  2. Take transducer from primary pump A, and swap with the primary pump B.
  3. Power on pump. If transducer error changes to Pump A: Transducer range error, then replace transducer.
  4. If pump B error still occurs, then power off pump, and swap the accumulator A transducer with the accumulator B transducer.
  5. Power on the system. When the error occurs on pump A, then replace the faulty transducer.

ADDITIONAL INFORMATION

Transducer 20K PSI part number: 700006045

ACQUITY UPLC BSM Transducer Part number 700002594

Avoid the use of halogenated solvents as these can lead to premature failure of transducers and result in this error being observed.
