Accelerometer signal output signal simulator
pC, mV, IEPE, TTL Meggitt Sensing Systems - Measurement Group

The Endevco® model 4830A is 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 other in-laboratory and field testing environments.

Available output signals from the model 4830A include single-ended and differential charge (pC), single-ended voltage (mV) and current-sinking ISOTRON® (IEPE). The included tachometer (TTL) output signal makes the unit a convenient and portable means of on-site instrumentation testing and servicing. Outputs are available in English or Metric units over an available frequency range of 1 Hz to 10 KHz, with an adjustable output amplitude of up to 10,000 pC or mV pk and with overall noise of <2 mV or 2 pC rms.

In addition, the model 4830A uses a menu-driven 80-character LCD display to establish appropriate settings. The key panel contains four sealed switches (per IP65) marked with arrows for cursor control. In addition to the manual on/off switch, the unit can be set for automatic power shutdown. The last setup is automatically stored within its non-volatile memory. Units are powered by internally mounted rechargeable batteries, which are fully rechargeable from a regulated 9 VDC power source. The power supply and a carrying case are included.
