EPRO A3311/022-000 Speed transmitter

The EPRO A3311/022-000 Speed Transmitter information can be summarized as follows:

Product overview
Brand: EPRO
Model: A3311/022-000
Type: Speed transmitter
Technical characteristics
This type of speed transmitter is used to monitor the speed of the shaft and give the key phase pulse.
It can be combined with eddy current sensors such as EPRO’s PR6422/… , PR6423/… , PR6424/… , PR6425/… , and PR6426/… Series) is used together to convert the pulse input of the eddy current sensor into an output proportional to the speed, and output a key phase pulse signal at the same time.
Built-in “self-test” circuit for monitoring sensor and transmitter circuit failures.
Application field
The speed transmitter is suitable for all types of turbomachinery, such as large and small steam turbines, fans, blowers, compressors, gear boxes, centrifuges, pumps, coal mills and others.
It is suitable for large equipment such as power plants, refineries and chemical plants, combined with fieldbus and PLC, main computer and network, and also suitable for independent monitoring of small turbomachinery with few measurement points.
Technical parameter
Measurement range: Not specifically mentioned, but generally applicable to a wide range of speeds.
Output signal: all the way proportional to the speed of 0/4… 20mA current output, and one key phase output.
Power supply: 18… 24… 31.2V DC.
Current consumption: about 100mA/24V.
Power consumption: About 2.5 watts.
Environmental conditions: in line with IEC359, DIN43745 standards.
Housing: Corrosion resistant, aluminum.
Protection level: IP65 (refer to DIN40050, IEC60529).
Matters needing attention
The transmitter has no explosion-proof function.
Initial setup is usually done by toggle switches and knob switches, factory Settings are the most commonly used way of working, but can also be set according to user requirements.
