Detail 990 Vibration Transmitter - Bently Nevada

Keterangan 990 Vibration Transmitter Brand : Bently Nevada main-990-vibration-transmitter The 990 Vibration Transmitter provides a 4-20 mA signal proportional to relative vibration designed for use on smaller, non-critical machinery. Its primary use is on centrifugal air compressors with fluid-film bearings. While the 4-20 mA signal is used primarily for trending, the 990 transmitter also has separate “ Prox Out” terminals and a “ Prox Out” BNC jack which allows you to view the actual vibration waveform when used with the 990 test adapter. Electrical : + Input : Accepts 1 non-contacting 3300 NSv Proximity Probe and extension cable. + Power Requires : + 12 to + 35 Vdc input at the transmitter terminal. + 4 to 20 mA Signal Output : 4 to 20 mA Signal Output + 4 to 20 mA Loop Accuracy : Within ± 1.5% over specified full-scale range. Accuracy is rated from the TEST signal input to the voltage measured across a 250 © loop resistance. + Probe Gap : Probe must be gapped between 0.5 and 1.75 mm ( 20 and 55 mils) from target to ensure full scale range. + Maximum Loop Resistance : 1, 000 © including cable at 35 Vdc. + Current Limiting : 23 mA typical. + Zero and Span : Non-interacting external adjustments. + NOT OK/ Signal Defeat : Signal output will go to less than 3.6 mA within 100 ¼ s after a Not OK condition occurs. Signal output is restored within 2-3 seconds after the Not OK condition is removed. + Power-up Inhibit : Signal output stays at less than 3.6 mA for 2 to 3 seconds after power is applied. + Proximitor Sensor Output : Compatible with ungrounded, portable test equipment. When using grounded, ac-powered test equipment, use the 122115-01 Test Adapter for signal isolation. + Output Impedance : Prox Out has a 10 k© output impedance calibrated for a 10 M© load. + Prox Out Linear Range : 1.4 mm ( 55 mils) . Begins at approximately 0.25 mm ( 10 mils) from target surface. + Prox Out Incremental Scale Factor : 7.87 mV/ ¼ m ( 200 mV/ mil) ± 6.5% typical including interchangeability errors when measured in increments of 0.25 mm ( 10 mils) over the linear range using a flat 30 mm ( 1.2 inch) target. Worst case 7.87 mV/ ¼ m ± 10% . Typical Noise Level: 50 mV/ pp. + Temperature Stability : Incremental scale factor remains within ± 10% of 7.87 mV/ ¼ m ( 200 mV/ mil) from 0 ° C to + 70 ° C ( + 32 ° F to + 158 ° F) . + Frequency Response : 5 Hz to 6, 000 Hz + 0, -3 dB. + Minimum Target Size : 9.5 mm ( 0.375 in) diameter. + Leadwire Length : Maximum for Proximitor* Sensor Output ( BNC connector) , maximum cable distance is 3 metres ( 10 feet) . + Non-Hazardous, Zone 2 or Div 2 Hazardous area locations 13 km ( 8 miles) maximum between transmitter and receiving device for signal output. + Intrinsically Safe Hazardous area locations 68 metres ( 225 ft.) maximum between transmitter and receiving device for signal output. + Electrical Classification : General Purpose Approval by Canadian Standards Association ( CSA/ NRTL/ C) in North America and by VDE in Europe. 990 has the CE mark for Europe.
