MMS3120022-000 Dual channel bearing vibration transmitter

Description

MMS3120022-000The dual channel bearing vibration transmitter MMS3120 is a part of the turbine monitoring protection transmission system MMS3000

component. Cooperate with epro seismic sensor (PR 9268/20 PR 9268/30 PR 9268/60 PR

9268/70, etc.) — start to use: other sensors can also be connected., Applications include various types of vortices

Wheel machinery, large and small turbines, fans, blowers, compressors, gearboxes, centrifuges, pumps,

Coal mill and other rotating machinery. The bearing vibration can be economically measured and monitored.

This system is suitable for large equipment in power plants, oil refineries and chemical plants. It combines fieldbus, PLC

The main computer is used together with the network, and is also suitable for independent monitoring of small turbomachinery with few measuring points.

This transmitter does not have explosion-proof function.

Built in “self check” circuit to monitor sensor and transmitter circuit faults. If a fault is found, the logic is “OK”

The output will change state, and the 4-20mA output will change to 0mA.

The MMS3120 dual channel bearing vibration transmitter converts the input of two independent electric speed sensors

Two independent outputs directly proportional to the peak value of vibration velocity or vibration displacement, or – one and two input signals

The maximum value of the vibration speed or peak value is proportional to the output.

Built in “self check” circuit to monitor sensor and transmitter circuit faults. If a fault is found, the logic is “OK”

The output will change state and the current output will change from 4-20mA to 0mA.

Sensor input:

Two independent electric speed sensor inputs, such as PR9266/ And PR26

Maximum allowable input voltage:+10V;

Input impedance:>100K0.

Measuring range:

Select by toggling the switch 5/10/25/50/100mm/s vibration speed range, and the vibration speed range is taken as

Depends on the input sensitivity of 30/28.5/22mV/mm/s
