Product Description
Product Description: MMS3210-021
I. Overview
MMS3210-021 is a dual channel axial displacement transmitter, belonging to the MMS3000 transmitter series, mainly used to monitor axial displacement, shaft position, thermal expansion and radial displacement, thrust bearing and valve position. The transmitter is particularly suitable for a variety of applications using eddy current displacement sensors.
Two, the main characteristics
Measurement input: Accept eddy current sensor as measurement input, built-in preprocessor, in line with API670 and other common standards.
Power supply: Adopts redundant 24Vdc power supply to ensure the stable operation of the system.
Self-check function: Built-in self-check circuit can monitor sensor and transmitter circuit faults, and change the logic “OK” output state when the fault is found, while the current output changes from 4-20mA to 0mA.
Output signal: Provide 0/4… 20mA current output for easy connection to various control systems.
Sensor compatibility: Support epro eddy current displacement sensor PR6422/… , PR6423/… , PR6424/… , PR6425/… , and PR6426/… .

APPLICATION
The application field of MMS3210-021 is very wide, mainly including the following aspects:
Turbomachinery monitoring
Suitable for all types of turbomachinery, such as large and small steam turbines, fans, blowers, compressors, etc. The monitoring of axial displacement, axial position, thermal expansion and radial displacement is very important to ensure the safe and stable operation of these machines.
Industrial Process Control:
The MMS3210-021 can be used to monitor the axial displacement and position of critical equipment in industrial processes to ensure that the equipment is operating within the specified operating range. For example, in the petrochemical, electric power, metallurgy and other industries, the transmitter can be used to monitor the operating status of pumps, gear boxes, centrifuges and other equipment.
Power plants, refineries, chemical plants and other large equipment:
These sites often have a large number of critical equipment, and their safe and stable operation is critical to the productivity and safety of the entire plant. The MMS3210-021 can be used in combination with fieldbus and PLC, host computer and network to achieve comprehensive monitoring and protection of large equipment.
Independent monitoring of small turbomachinery with few measuring points:
For some small turbomachinery with fewer measurement points, the MMS3210-021 can be used as an independent monitoring device to achieve real-time monitoring of the displacement and position of the equipment axis to ensure the safe operation of the equipment.
