ACOtron - Model 4212 - IEPE -Accelerometer Preamplifier
The ACOtron 4212 is designed to work with both prepolarized (electret) measurement microphones, accelerometers and other charge devices. The 4212 may be powered from industry standard IEPE or CCLD (Constant Current Line Drive) sources like the IEPE equivalents found in many measurement instruments. The 4212 permits maximum utilization of available current and supply voltage.
At 20 mA CCLD the 4212 is capable of providing 14 Vpp at 20 kHz into a 50 nF (50,000 pF) line load - the equivalent of over 3000 feet of low capacitance coax cable. Yet it also performs quite well at 4 mA providing the same 14 Vpp output at 20 kHz into a 5 nF load. The uV (typ) "A" weighted noise floor assures an excellent dynamic range.
Companion prepolarized measurement microphone capsules and power supplies round out the offering. The MK224 is a Free Field microphone capsule providing 50 mV/Pa sensitivity, 20 kHz frequency response and a
7052E IEC61094-4 compliant prepolarized microphone capsules incorporate Titanium Diaphragm, and "0" Temperature Coefficient (TC ) insulator construction to offer IEC61094-4 compliant performance. The 7052E provides Free Field response, 35 mV/Pa sensitivity and >25 kHz frequency response.
The 4212 and DM2-1K may be used as a preamplifier for Quartz accelerometers and other passive transducers requiring high input impedances. The DM2-1K may be used to connect them to the 4212.
