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 Ω 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 Ω 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 μs 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 kΩ output impedance calibrated for a 10 MΩ 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/μm (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/μm ± 10%. Typical Noise Level: 50 mV/pp. Temperature Stability Incremental scale factor remains within ±10% of 7.87 mV/μm (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. Environmental Limits Transmitter Temperature Operating Temperature -35 °C to +85 °C (-31 °F to +185 °F) Storage Temperature -51 °C to +100 °C (-60 °F to +212 °F) Probe Temperature Operating Temperature -35 °C to +177 °C (-31 °F to +350 °F) Storage Temperature -51 °C to +177 °C (-60 °F to +350 °F) Relative humidity 100% condensing, non-submerged, with protection of coaxial connectors.
