Simulating transducer outputs for testing applications

摘要

Meggitt Sensing Systems has introduced the Endevco model 4830A, a handheld, lightweight battery-operated electronic instrument, designed to simulate a variety of transducer outputs. The simulator offers a convenient and portable means of verifying instrumentation settings and cable integrity in aerospace and automotive test cells, as well as laboratory and field testing. Available output signals from the model 4830A include single-ended and differential charge (pC), single-ended voltage (mV) and current-sinking ISOTRON. The inclusion of a tachometer output signal makes the unit a convenient and portable means of on-site instrumentation testing and servicing. Simulated outputs are available in either imperial or metric units over an available frequency range of 1Hz-10kHz, with an adjustable output amplitude of up to 10,000pC or mV pk and with overall noise of <2mV or 2pC rms.
