Overview

The NE3911/NE3911E axis displacement transmitter and precision measurement circuit are integrated together, realizing the function of the traditional "sensor+monitoring instrument" mode vibration measurement system. It is suitable for building an economical high-precision vibration measurement system. The transmitter can be directly connected to DCS, PLC or other systems, and is an ideal choice for vibration measurement of factory equipment such as fans and pumps.

Product Details

NE3911/NE3911EAxial displacement transmitter

External power supply: 24V DC+5%
inputSignal: taken from the signal of the built-in vibration speed sensor
Sensitivity: 20mV/mm/s ± 5%
Frequency response: 5-300Hz
Range: 0-500um (peak to peak) or 0-50.0mm/s (true RMS)
Measurement error: ± 1% of full scale
