Overview of ag19 / 20 pulse transmitter
Ag19 / 20 pulse transmitter is a kind of shaft angular displacement sensor. It is used with elliptical gear flowmeter (OI, OM Series). It can convert the flow of measured medium into electric pulse signal. Two ag19 / 20 pulse transmitters are installed on the transmitter disk. The transmitter has obtained the explosion-proof certificate with the number of gyb00568.
working principle
Ag19 / 20 pulse transmitter is composed of oscillator, detector, comparator and galvanostat. When the slotted metal sheet rotates in the coupling coil of the oscillation circuit and the detector, it interferes with the magnetic line of force and makes the oscillator or oscillate. Finally, the output current of the constant current source changes continuously, and the transmitter outputs a pulse train in the form of current.
1. Adopt two wire system (signal and power supply share wire) 2. No contact, reliable transmission. 3. Long transmission distance, strong load capacity. 4. Intrinsically safe explosion-proof structure
technical parameter
1. Output signal: rectangular current pulse, high level greater than 4mA, low level less than 1mA (within the specified load range).
2. Sending frequency: directly proportional to the matching flowmeter less than
3. Slot number: 20 slots
4. Allowable working voltage: DC 6V ~ DC24 V, harmonic content less than 5% (explosion proof type must be powered by safety barrier).
5. With load capacity: no more than 2K Ω (DC12V power supply); no more than 5K Ω (DC12V power supply), no more than 5K Ω (DC24V power supply).
6. Ambient temperature: - 20 ℃ ~ + 60 ℃ relative humidity: 10 ~ 85%
7. Remote transmission distance: the transmission connecting cable shall not be greater than 100 Ω / each core wire
8. Explosion proof sign: Exia Ⅱ CT5
9. Supporting safety barrier: kn5012
Explosion proof performance and connection
Ag19 / 20 pulse transmitter is used in combination with elliptical gear flowmeter (OI, OM Series). It can be used in Exia Ⅱ CT5. The explosion-proof form is intrinsically safe. If the display instrument or system is connected with ag19 / 20 pulse transmitter, it must be equipped with safety barrier.
