2.6 Permissible Changes

SensoGate WA131M can be adapted to changed conditions by the customer. Prior to making any

changes, contact Knick Elektronische Messgeräte GmbH & Co. KG. The following are examples of possi-

ble changes:

• Change to a different process connection

➜

Process Connections, p. 18

• Replacement of process-wetted components (calibration chamber, immersion tube, gaskets) with

other material characteristics

➜

Maintenance, p. 33

• Modification of the sensor holder to fit another sensor type

➜

Drives and Sensor Holders, p. 18

• Retrofit of safeguards, e.g. “Immersion lock without a mounted liquid-electrolyte sensor”

➜

Safeguards, p. 6

Any changes may result in deviations between the information on the nameplate and the actual ver-

sion of the SensoGate WA131M. The operating company is responsible for evaluating the permissibil-

ity of the changes and for documenting and identifying the modified version.
It is recommended that changes to the SensoGate WA131M are carried out by the Knick Repair Ser-

vice. After making the necessary changes, a functional and pressure test is carried out and, if neces-

sary, a modified nameplate is attached.
More information on changes can be found in the related supplementary datasheet. Maintenance

instructions with detailed instructions for action are available on request.
