Overview

The NE3951/NE3951E bearing vibration transmitter (displacement) can be widely used for measuring and protecting the vibration of large rotating machinery (bearing cover vibration) in industries such as power, metallurgy, petrochemicals, steel, and papermaking. Mainly monitoring the vibration of rotating machinery rotors, monitoring the increase in vibration caused by rotor imbalance, misalignment, and loose parts. The $r $n vibration transmitter has a metal shell on the outside, a flexible thin film panel, and uses surface mount components on the inside. Technically, the principle of equal precision measurement is applied

NE3951/NE3951EBearing vibration transmitter(Displacement)

Overview

NE3951/NE3951EBearing vibration transmitter(Displacement)Can provide dynamic signal output. The installation and debugging of the transmitter are convenient, with excellent frequency response characteristics, high measurement accuracy, good stability, and long service life; And it is equipped with high temperature impact protection, overload protection, reverse connection protection, and lightning protection; Multiple vibration range options are available; Optional two wire, three wire, four wire and other wiring methods; If necessary, the header with on-site LCD display can be selected. It is an ideal choice for long-term online vibration monitoring of rotating machinery such as fans, pumps, compressors, engines, fans, generators, motors, steam turbines, turbochargers, etc. (vibration of casings, bearing housings, or mechanisms). Suitable for industrial sites under moderate temperature conditionsVibration velocity sensor installed on site
