Overview
The rotating speed transmitter senses the convex teeth or concave grooves on the magnetizer according to the Hall element, and converts the signals into analog communication RS485 output, and realizes the rotating speed measurement through the processing output of the internal precision circuit. It can be used to detect the rotating speed of various rotating machinery.
Field of application
Speed transmitter can be widely used in power, metallurgy, petrochemical and paper industries large rotating machinery (such as steam turbines, compressors, motors, fans, pumps, etc.) Speed and zero speed measurement. At the same time, it is also widely used in the fields of workpiece processing speed monitoring, steel pipe coating speed monitoring and gear speed measurement.
Characteristic
1. Output signal is strong
2. And that anti-interference capability is strong
3. Non-contact measurement
4. Wide operating range (low speed can be measured)
5. Can be used in harsh environments such as smoke, oil and gas, water mist, etc.
Technical parameters
Working power supply: 9-30Vdc (wide voltage supply)
Power consumption current:
4-20 mA output power consumption: ≤ 45 mA
RS485 output power consumption: ≤ 15mA
Measuring range:
0 ~ 15000rpm (60 measuring points per circle)
0 ~ 30000 rpm (30 measuring points per circle)
0 ~ 90,00000rpm (1 measuring point per circle)
The conversion formula is as follows:
Speed = 60 * Frequency/ (number of measurements per cycle)
