Keep the sensing element at the test point and the electronics in a verified cooler zone. Configure a passive charge-output sensor, its hot-zone cable and the remote conditioning as one measurement chain.

PZA-CHG / INSTALLATION DECISION
The hot probe and the remote electronics have different limits.
A charge-mode probe separates the sensing element from the electronics. Request the continuous temperature, dwell and thermal transients at the mounting surface, then specify the insulation resistance at that temperature. A room-temperature sensitivity alone does not describe the hot chain.
Above the confirmed rating of a flexible cable or connector, review a mineral-insulated hardline section, termination and minimum bend radius. The cooler low-noise coax segment and the conditioner must each remain inside their own limits. A fixed distance of two metres is not a temperature specification.
Annular shear and compression constructions respond differently to mounting strain and thermal transients. Request the exact mounting drawing and base-strain/temperature data for the proposed configuration. Cryogenic operation is a separate minimum-temperature review.
Original engineering concept. Any numerical example is illustrative; actual hardware and installed performance require confirmation.
Can the +480°C request use ordinary +260°C PTFE coax in the hot zone?
No. Review the hot section separately. A cooler PTFE section may be proposed after its actual local temperature, connector and insulation have been checked.
Is PZA-CHG-400 automatically interchangeable with Endevco 2273AM1?
No. The PZA code is a request profile. Confirm sensitivity, temperature-dependent insulation, complete suffix, housing, mounting, cable and calibration before approving a substitution.
Which conditioner belongs with a high-temperature charge probe?
Match the sensor’s hot-state resistance, peak charge, polarity and measurement window to a suitable charge amplifier or converter, then verify the receiving DAQ input.
Confirm the PZA-CHG output before connecting the DAQ.
Conceptual signal paths. Actual electrical and thermal limits require a configuration review.
PZA-CHG / QUOTE & CAD
Send the PZA-CHG configuration, channels and document scope.
Accessories are optional quotation requests. Selection and final pricing follow the electrical, mounting and temperature review.
CAD / CALIBRATION / QUOTATION
Request the documents that close the engineering review.
Temperature-dependent sensitivity and insulation, cable termination, mounting surface and local hot/cold zones.
Controlled datasheet & CAD
Ask for the quoted configuration, revision, complete dimensions, tolerances, mounting thread, cable and connector. STEP availability is confirmed against that exact configuration.
Calibration & traceability scope
State reference frequency, amplitude, excitation and temperature. Request available sensitivity, capacitance, transverse response and frequency/temperature records. A named calibration standard alone is not a test result.
Formal quote / PI inputs
Include sensor and channel counts, accessories, calibration scope, destination, delivery window and required documents. Prices and availability are confirmed in the quotation.
No released PZA CAD, measured certificate or commercial quote is supplied by these concept pages. Select the required documents in the RFQ; we will confirm what can be provided for the proposed configuration.
