It is mainly composed of magnetic circuit system, inertial mass and spring damper. The Sensor housing is equipped with a magnet inside in a rigid manner, and inertial mass (coil block) is hung on the housing with spring element. In case of vibration within the working frequency range of the Sensor, coils and magnets make relative movement to cut magnetic lines and to produce induced voltage inside the coils, and the voltage is directly proportional to the vibration velocity.2. Functionsl Themeasured object is housing vibration of rotating machinery bearing seatin vertical and horizontal, directions (housing/bearing vibration);l Outputsignal is directly proportional to vibration velocity, and application fields of high frequency, intermediate frequency and low frequency can be taken into account;3. Characteristicsl Built-inhigh-performance components ensure the stability of output signal in long-term use and strong environmental disturbance resistance;l Powersupply is not required, which is more applicable for use in severe environment with smoke, oil & gas, dust, etc. Waterproof type can beinstalled in the open air.4. ApplicationMonitoringof housing vibration of various large rotating machinery (steam turbine, fan, pump, compressor, centrifugal machine, hydraulic turbine, etc.)5. Technical Specificationsl Measurement range:Max. measurable displacement: 2000μm (Pk - Pk) (0~-3dB)Frequency range Standard type: 10~1000hz; low frequency type: 5~1000hz l Installation direction:fixed surface of Sensor in a lower place (0°)5Hz vertical type: 0°±2.5°;5Hz horizontal type: 90°±2.5°;10Hz general type: 0°±100°; l Output sensitivity:20m V/mm /S ±5%;(500mV/in/sec±5%)Test at the frequency of 80Hz and the velocity of 10mm/s; 300m (1000 feet) field wiring. l Electrical characteristics:Output DC resistance: ≤1KΩInsulation resistance: ≥2MΩOutput non-linearity: ≤3%Transverse sensitivity ratio: ≤5%l Signal output:Two-pin aviation plug: 1# pin (red), 2# pin (white) l Physical characteristics:Overall dimension: Ф1.6in ×4 in Ф41×102mmWeight: 500g (excluding cable) l Environmental limitations:Service temperature: -30℃~+120℃ (-22oF~+248 oF)Humidity: 0 ~ 95% (non-condensing) ,dust and moisture prevention.l Reference standardsl Executive standardsThe United States Petroleum Association Standard: API 670Safety certificate: CE;Protection level: IP65;Explosive-proof grade: ATEX: Ⅱ2G ExdⅡCT4/BT4 Anti-electromagnetic interference: EMC/LVDRefer to EN55011\ EN 61010\ EN50081\EN50082.6. Ordering information General type: general installation; aviation plug goes out from top or sideAN1930-AXX-BXX-CXX-DXX-EXX-FXX5Hz vertical type: vertical installation; aviation plug goes out from topAN1930- AXX-BXX- CXX -01-00- -FXX5Hz horizontal type: horizontal installation; aviation plug goes out from sideAN1930- AXX-BXX- CXX- 02-01 -FXXStandard model:General type: AN1930 - 00-05-01-00-00-00Vertical type: AN1930 - 00-05-01-01-00-00Horizontal type: AN1930 - 00-05-01-02-01-00A: Spec. of mounting thread:00 - M10×1 stud02 - 1/4″-28UNF studXX - otherB: Cable length:00 - 0m (no cable)05—5mXX - otherC: Cable armoring00 – Unarmored cable01 –Armored cableD: Installation direction and minimum working frequency00 - General type: 0°±100°/10Hz01 - Vertical type: 0°±2.5°/5Hz02 - Horizontal type: 90°±2.5°/5HzE: Aviation plug outgoing line00 - out from top01 - out from sideF: environmental limitations00 - no requirement01 - ATEX: Ⅱ1 G ExiaⅡC T4Ordering accessories:AN1930A: retaining screw: 1/4-28UNC to M10×1AN1930B: retaining screw: 1/4-28UNC to M6AN1930C-XX: unarmored cable of a few metersAN1930D-XX: armored cable of a few meters

It is mainly composed of magnetic circuit system, inertia mass and spring damper. A magnet is rigidly fixed in the sensor bearing; the inertia mass (coil block) is suspended on the bearing by a spring element. When vibration is produced, the coil and magnet move relativelywithin the operating frequency range of the sensor; the magnetic line of force is cut, and induced voltage is generated within the coil; voltage value is in direct proportion to vibration velocity or displacement value.2. Functionsl Theobject of measurement includes vertical and horizontal (X/Y/Z) vibration (bearing vibration) of bearing pedestal or rack of a rotary machine;l The output signals are in direct proportion to vibration velocity or displacement; the sensor applies to the field of ultralow frequency vibration measurement.3. Featuresl Embeddedwith high-performance elements, and stable for long-term use of output signals, and high in immunity from environmental disturbance;l Active.4. ApplicationMainlyapplies to vibration measurement of water turbine sets, pump stations, low speed operating machines (mills), and engineering construction (damsand bridges).5. Technical Datal Range limit:Frequency range: 0.5 ~ 100Hz (-3dB). l Installation direction:(0°: sensor clamping surface is beneath)Horizontal: 90°±2.5  Vertical: 0°±2.5°.l Output sensitivity:Velocity type: 300m V/mm/S (7.5V/in/s) ±5%Displacement type: 7.87mV/μm (200mV/in/s) ±5%l Electrical characteristic:Power supply: -24VDC/+24VDC;Output degree of nonlinearity: ≤3%.l Signal output:Aviation plug: 1: power supply, 2: common, and 3: signal;Direct outlet: 3-core shielded cable.l Physical property:Outline dimension: Ф44×140mm;Way of installation: Base plate installation, fixed by two M5 bolts, with a space of 56mm;Weight: 700g (excluding cables).l Environmental restrictions:Operating temperature: -30℃ ~ +120℃ (-22oF ~ +248 oF);Humidity: 0 ~ 95%, (non-condensing).l Executive standardsThe United States Petroleum Association Standard: API 670Safety certificate: CE;Protection level: IP65;Explosive-proof grade: ATEX: Ⅱ2G ExdⅡCT4/BT4 Anti-electromagnetic interference: EMC/LVDRefer to EN55011\ EN 61010\ EN50081\EN50082.6. Ordering information AN1931- AXX-BXX-CXX-DXX-EXXStandard model:Displacement type horizontal: AN1931--05-00-01-00-00Displacement type vertical: AN1931--05-00-00-00-00Velocity d type horizontal: AN1931--05-01-01-00-00Velocity type vertical: AN1931--05-01-00-00-00A: Cable length:05--5m10--10mXX--OthersB: Output form:00--Displacement type: 7.87mV/μm (200mV/in/s)01-- Velocity type: 300mV V/mm/S (7.5V/in/s)C: Way of installation:00--Vertical installation01--Horizontal installationD: Power supply:00-- -24VDC01-- +24VDCE: Outlet method:00--Direct outlet (waterproof type)01--Aviation plug:
