The NE3402E two-wire integrated vibration speed transmitter is designed and manufactured based on the use of harsh environmental conditions. Please select the product according to the site conditions. NE3402E two-wire integrated vibration speed transmitter is based on our NE3402S (three-wire) vibration transmitter, using our many new patented technologies; the loop conversion power supply, piezoelectric sensor, low power precision Measurement circuits and the like are integrated.

working principle

The NE3402E transmitter (hereafter referred to as the transmitter) has a built-in MEMS piezoelectric element that senses the vibration speed, converts the acceleration into a peak speed/effective value through a high-precision integrated circuit, and converts the peak speed/effective value to 4-20 mA of the corresponding range. Current output for easy remote display and control; ideal for connection to DCS, PLC and data acquisition systems.

 Performance characteristics
