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.
Intake manifold gasket is a flexible, fitted part of engine that helps prevent air from leaking out during fuel combustion and help the regulate chamber temperature.
The intake manifold gasket fits between intake pipe and cylinder heads, and its main purpose is to reduce the chance of air leaking out, which can hurt the car`s efficiency.
People who have weak or faulty Intake Manifold Gaskets may notice their engines sputtering out or stalling more frequently.
The exhaust manifold gasket is more likely renewing than the intake manifold gasket, because the exhaust system heat caused more damage.
Modern exhaust Manifold Gaskets are made of beaded multilayer steel (MLS). These metal beads are always reinforced with metal sheets to resist the component movement that arises from large fluctuations in temperature. The sheet layers number is depends on distortion of the exhaust manifold and cylinder head components.
Exhaust manifold gasket leak can cause bad exhaust values, loss of power and increase the fuel consumptions.
