SCZB-08 speed sensor
I. Overview:
The sensor adopts the principle of electromagnetic induction to achieve the purpose of speed measurement, with large output signal, no amplification, good anti-jamming performance, no external power supply, and can be used in the harsh environment of smoke, oil and gas, water vapor, gas and so on.
Second, technical data:
 1, output voltage: When the gear module is 4, the tooth 60, the material g3, the clearance is lmm
 1000 rev / min >5V (RMS)
 2000 rev/min >10V (effective value)
 3000 rev / min >15V (RMS)
 2, DC resistance:  130 ohms to 140 ohms (if the customer needs to use other resistance data, indicate when ordering)
3ã€Insulation resistance: >50MΩ at 500V DC
 4, working temperature: -20 °C ~ l20 °C
The angular displacement can be converted into electrical signals for counter counting. Non-contact can measure the speed and linear velocity of various magnetic materials such as gears, impellers, disks (or shafts) with holes (or slots, screws).
The sensor has the advantages of small size, strong and reliable, long life, no need of power supply and lubricating oil, etc., and can be matched with the general secondary speed meter.
Main Specifications:
Output wave type: Approximate sine wave (≥50r/min)
Output signal amplitude: ≥300mV
Sensor core and measured tip clearance φ=0.5mm
Measured gear module m=2
Number of teeth Z=60
Material: Electrical steel
The magnitude of the signal amplitude is proportional to the rotation speed and is inversely proportional to the size of the iron core and tip clearance.
Measuring range: 50～5000r/min
Use range: continuous use.
Working conditions: temperature -20 ~ 60 °C;
Relative humidity ≤85%, non-corrosive gas sensor adopts Hall effect, when the metal tooth passes the front end of Hall sensor, it causes magnetic field change, Hall element detects magnetic field change, and converts into an alternating electric signal, the built-in circuit of the sensor The signal is amplified and reshaped to output a good rectangular pulse signal. The measurement frequency range is wider, the output signal is more accurate and stable, and the installation is simple. It is oil-proof and waterproof, and it has been widely used in the fields of electric power, automobiles, aviation, textiles, and petrochemicals. application
2 Technical parameters
2.1 Operating Voltage: DC5~24V
2.2 Measurement Range: 0~20KHz
2.3 Speed ​​measuring gear form: Modulus 2 to 4 (involute gear)
2.4 Output signal: square wave, whose peak-to-peak value is equal to the working supply voltage amplitude, independent of the rotation speed, the maximum output current is 20mA.
2.5 Operating Temperature: -30 to +150°C
2.6 Thread Size: Φ16 Sensor (Installation Thread: M16×1)
2.7 installation gap: 1 ~ 2mm
Precautions:
1. The metal shield in the sensor output line should be connected to the earth zero line.
 2. It is not allowed to use and place in a strong magnetic field environment with a temperature of 25°C or higher.
 3. Strong impacts should be avoided during installation and transportation.
 4. When the measured shaft fluctuates greatly, attention should be paid to properly amplifying the gap to avoid damage.
5. The sensor is designed to be used in harsh environments, so it is sealed after assembly and commissioning and cannot be repaired.
BRIGHT STEEL BAR
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
