PZA-AMP / INSTALLATION DECISION

A conversion gain is useful only inside both input and output limits.

System sensitivity is sensor pC/g multiplied by converter mV/pC. Peak output also includes peak g. Check the converter input-charge limit as well as output voltage swing, bias and DAQ compliance; a gain calculation alone cannot approve the chain.

The 100, 10 and 1mV/pC PZA identifiers are gain requests. Other gains, including 0.5 and 0.1mV/pC, can be described in a custom request. Input charge, bandwidth and source resistance cannot be copied from a different gain or original-model suffix.

Polarity must be read from the exact sensor and conditioner specifications. For example, the original 357B03 page states negative output, while the 2221F sheet states positive output for acceleration into the base. Request an inverting or non-inverting path after checking the coordinate convention.

A laboratory instrument may offer adjustable gain, filters, time constants or integration. Ask which functions are included in the proposed PZA-2635-LAB configuration; an original B&K feature list is not proof of supplied PZA functions.

Charge sensitivity, conversion gain, polarity and receiving DAQ headroom checked as one chain
Original engineering concept. Any numerical example is illustrative; actual hardware and installed performance require confirmation.
Is a standard 422E reference suitable for every hot charge probe?

No. Some general converters have minimum source-resistance requirements. Hot sensor insulation and the exact converter specification must be reviewed together.

Can a converter connect to any IEPE DAQ?

Verify excitation current, compliance voltage, bias, output swing, frequency response and connector. An interface name alone does not establish compatibility.

How do I request a three-channel chain?

Select the three-axis sensor profile and request three matched conditioning channels. State the gain and polarity per axis, the breakout cable and the receiving inputs.

PZA-AMP / CONFIGURATION REVIEW

Define the test envelope.

Remote conditioning of high-temperature charge sensors and laboratory vibration measurement chains.

Requested options for review — these are configuration targets, not released specifications.
Inline requestPZA-422 charge-to-IEPE converter; gain, input charge and output swing to confirm
Laboratory requestAdjustable gain and filtering; requested voltage output up to ±10 V by configuration
Gain conventionmV/pC; inverse sensitivity pC/mV must be identified explicitly

Range, temperature, sensitivity and bandwidth combinations require model-specific confirmation, controlled drawings and calibration requirements.

Before you select

  1. Check input charge and voltage headroom separately; g × pC/g × mV/pC gives mV.
  2. Confirm current supply, compliance voltage, bias, noise and discharge time constant.
  3. Place electronics in a verified temperature zone; distance from the probe alone is not a temperature rating.
