Sensor system Components of AN1808 8mm proximity Sensor system:l AN1811 Probe ;l AN1880 Extension cable;l AN1800 8mm proximitor. Sensorsystem output is proportional to the voltage signal changing with the gap between the probe end and the measured conductor surface. It can notonly be used for static (shaft position) signal measurement, but also used for dynamic (shaft vibration) signal measurement. It is mainly usedfor the shaft vibration, shaft displacement, key phase, speed and eccentricity of film sliding bearing rotating machinery.AN1811 11mmproximity Sensor system follows the 670 Standard made by American Petroleum Institute (API) for this kind of Sensor completely. All AN1811 11mm proximity Sensor systems can reach specified performance criteria and the probes, extension cables and proximitors are fully interchangeable, no independent matching or calibration is required. TheSensor system is safe and explosion-proof in essence and it will not cause spark under electrical operation.Proximitor AN180011mm proximitor has two types of mounting base plate. It can select DIN35mm guide rail or traditional panel for mounting. The base plate is insulating when either kind of mounting method is adopted and no separate insulating plate is required.AN180011mm proximitor housing is cast from aluminum. To shield external interference, the housing and the signal public terminal (signal earth) are connected inside the proximitor. As the mounting base plate and guide rail seat are made of insulating engineering plastics, it can be ensured that the proximitor housing and earth are isolated when a proximitor is mounted, the radio interference resistance ability is improved and the European RFI/EMI anti-radiation standards can be reached.AN1800 11mm proximitor uses Spring Loc terminal which can be fixed automatically, and wiring can be realized without erecting tools. Besides, it will not get loose for boltfixing is not required.Fault toleranceof AN1800 11mm proximitor: any wiring fault of supply terminal, common terminal (SG) and output terminal can not damage the proximitor, and it has the function of power polarity error protection and output short-circuit protection.Probe and extension cable Allparts of AN 1811 11mm probe are connected through mechanical deformation to ensure its stability and reliability in severe environment.For all connectors of AN 1811 11mm probe and AN1880 extension cable, gold-plated copper connectors are adopted as per MIL-C-39012 (the military specification ofthe U.S.). These connectors only need to be fixed manually (connectors can be locked automatically), and special mechanical locking device can prevent loose connection.Connectors at two ends of AN1880 extension cable are different. The connector with male thread (adapter) is coupled to probe, while the connector with female thread is coupled to proximitor. Fluoroplastics resistant to highand low temperature and chemical corrosion are used for cable insulation and sheath.2. Technical Specificationsl Linear range: 4.0mm (160mil)Linear range is from the position about 0.50mm (20mil) from surface of the target: 0.50~4.50mm (20~200mil). l Sensitivity: 3.94mV/μm (100mV/mil)Thesensitivity is less than 3.94mV/μm (100mV/mil) ±5% within the linear range of 4.0mm (160mil) including interchangeability error. l Probe installation clearance: 2.50mm (100mil). l Frequency response:0~8KHz, typical value of 0~-3dB, 300m (1000 feet) field wiring. l Power supply:DC supply: -24VDC (-23~-26VDC);Power consumption: current consumption is no more than 20mA. l Requirements for target:Diameterof target (width of toroid): 30mm (1.2in) not less than 2 times of diameter of probe head; calibrate it on site if the detected surface is small.Shaft diameter: minimum 76mm (3in), 150mm (6in) recommend; pay attention to installation distance between probes to avoid mutual effect when diameter is less than 76mm, and ensure the distance is no less than 65mm (2.6in).Calibration of target material: 40CrMo steel/AISI4140 steel; calibrate it if the target material is inconsistent. l Interchangeability error:Error of interchangeable probe of the same type is ≤±5%;Error of interchangeable extension cable of the same type is ≤±5%;Error of interchangeable proximitor of the same type is ≤±5%; l Field wiring:Using0.5~1.5mm2 three-core shield cable; distance between proximitor and probe is less than 300m (1000 feet). When using a longer cable, signal suffers from attenuation, which needs calibration on site. l Environmental limitations:Probe and extension cable:Probe head pressure: less than 12MPaTemperature: -50℃~+170℃(-58oF~+338 oF)Working medium: air, oil, water, ammonia hydroxide.
