1.5.3 Output
d.c. voltage with superimposed ac signal corresponding
to vibration or displacement of the shaft.
Open−circuit and short−circuit proof.
Output voltage range: J2 closed: −2... − 18V (factory setting),
J2 open: −4... − 20V,
adjusted with 100kΩ load resistance
Limit range −1....−22V (at –24V supply voltage)
Nominal frequency range: 0...20kHz (–3dB) with C – load = 10nF
0...15kHz (−3dB) with C – load = 20 nF
Rise time: < 15μs, with C − load = 1nF
Output impedance: approx. 100Ω
Load resistance: nominal value 100KΩ (for R = 10KΩ, error <1%)
1.5.4 Errors and tolerances
Error of gain factor <1% in range 0....1000Hz and with C − load < 20nF
Supply voltage response
of output signal: < 20mV/V
Long term drift 0,3% max. (in range: −30...+70°C)
Temperature response:
− on the average output signal: < 200mV / 100K (in range: −30...+70°C)
− on the gain factor: < 2 % / 100K (in range: −30...+70°C)
Interferences < 10mV
rms
with 1nF C − load
Calibration with soldered resistors and potentiometers in the
converter an adjustment on several sensor types and
target materials is possible. The adjustment is made
at the factory, but may be made by the customer or by
a service engineer on site if special adjustment tools
are available. The adjustment procedure is described
in chapter 3.4.
Errors of the measuring chain
These error definitions are related to the nominal measuring range (reference value). Linearity
errors are defined as deviations from the linear curve, which crosses the –10V value (−12V if
J2 open) and which gradient is defined by the nominal sensitivity.
Absolute linearity errors for standard measuring ranges:
PR 6422 1,5%;
PR 6423 1%
PR 6424 1,5%
PR 6425 0...− 6%
PR 6426 1,5%
