MTN/8302 Accelerometer Simulator
- Manufacturer: Monitran
- Category: Calibrators and Simulators, INSTRUMENTATION
Portable accelerometer simulator that emulates a constant current sensor (IEPE) to test and calibrate vibration monitoring systems without subjecting the machine to actual vibration. 156 Hz sinusoidal signal. Amplitude accuracy ±2% and frequency accuracy ±1%.
Two selectable output levels with a 3-position switch (OFF / 10 / 100): 100mVrms (equivalent to 1g or 10 mm/s) and 1Vrms (equivalent to 10g or 100 mm/s). Simulated bias voltage of 6V to 8V DC for the system to detect the sensor OK condition.
Two LEDs on the front panel: «TDX OK» indicates the presence of 18V–24V power; the other indicates the presence of the simulation signal. BNC socket on the front panel. 9V battery (PP3 type). ABS housing measuring 158 mm x 95 mm x 33 mm. Compatible with Monitran MTN/6000 systems and similar instrumentation.
- Two levels: 1g / 10 mm/s and 10g / 100 mm/s.
- Reference frequency: 156 Hz.
- «TDX OK» LED for 18V-24V power supply.
- 9V battery and BNC connection.
Technical Frequently Asked Questions
1. What signal levels does it generate?
It has a three-position selector. In position «10» it generates 100mVrms, equivalent to 1g or 10 mm/s depending on the monitor settings. In position «100» it generates 1Vrms, equivalent to 10g or 100 mm/s.
2. How can you tell if the system is supplying power to the sensor correctly?
The «TDX OK» LED illuminates when the simulator detects that the connected system (such as an MTN/6000 rack or PLC) is supplying the necessary constant current (typically between 18V and 24V). If it does not light up, there is a loop power failure.
3. Why does it use a fixed frequency of 156 Hz?
At 156 Hz there is a direct equivalence between acceleration and velocity (RMS). The fixed and known frequency facilitates the verification of signal conditioning cards.
