Vibration TransmittersIdentity and reference conditions
Check model, unique serial, date, detector, full scale, test temperature, mounting and reference instrument. Ask how the reference calibration is traced and whether the claimed scope covers the work.
CALIBRATION / SERIAL NUMBER / MEASUREMENT CHAIN
Calibration & quality assurance for vibration transmitters.
Define the evidence your receiving inspection needs before the hardware is ordered. Match each instrument’s detector, range and current output to its model and serial-number record. Record the PLC input checks and agreed criteria for your evaluation units.

PILOT EVALUATION / PLC INPUT SCALING
Record a 4–20mA loop check before the plant rollout.
Enter observations collected under your plant’s approved commissioning procedure. The initial 0–25.4 mm/s span and 4 / 12 / 20mA points are worksheet examples. Set the actual channel scale and record its displayed readings. Enter the endpoints and readings in the selected engineering unit.
| Applied current (mA) | PLC indication (mm/s) | Expected (mm/s) | Signed error (mm/s) | Error (% span) | Observation |
|---|---|---|---|---|---|
| 0.000 | — | — | Pending reading | ||
| 12.700 | — | — | Pending reading | ||
| 25.400 | — | — | Pending reading |
Expected = low + (mA − 4) ÷ 16 × (high − low). Percentage error uses the configured engineering span. Currents outside 4–20mA are retained for module-specific diagnostic review. Agree acceptance limits with the responsible plant engineer.

Agree the evidence for each part of the evaluation.
| Check | Conditions to record | Evidence for review |
|---|---|---|
| PLC input scaling | Configured current mode, engineering endpoints, input filter and reference current source. | Applied current, displayed PLC value, calculated indication error and buyer-approved criteria. |
| Transmitter measurement chain | Model, serial number, quantity, detector, range, reference vibration, method and uncertainty. | Configuration-specific calibration report and reference traceability. |
| Installed machine pilot | Mounting, measurement direction, speed, operating load, band, temperature and baseline. | Approved commissioning observations, trend review and corrective actions before rollout. |
The worksheet applies linear normalization to the entered 4–20mA span, then maps it to the configured engineering endpoints. Siemens documents these normalization and scaling operations. The PLC’s actual raw-count endpoints depend on the selected channel configuration. Siemens NORM_X / SCALE_X documentation ↗
Record the receiving module, signal and engineering endpoints, sample period and filter settings used for the test. Rockwell’s module configuration documentation identifies these settings. Use the manual for your actual module when checking overrange and diagnostic behavior. Rockwell analog-input configuration documentation ↗
Review module scaling and loop-load calculations →Connect the serial number to the measured output.
A useful calibration record identifies the measurement quantity, detector and output scale. Comparison calibration methods such as ISO 16063-21 require a defined reference and procedure. Agree the actual method, laboratory scope and uncertainty with the supplier for your configuration.
Output and frequency response
Request zero/current offset, sensitivity at a stated reference frequency, measured current at specified vibration levels and relevant frequency response points. Include limits and uncertainty in the acceptance agreement.
Receiving verification
Match the received label to the quoted drawing, report serial number and wiring. Check zero, span and machine mounting against your approved installation and commissioning procedure.
Request the tests that match the installation.
