The 990-10-70-01-00 transmitter provides premium machinery condition monitoring by converting proximity probe signals into industry-standard current loops. Specifically, this device interfaces perfectly with a 3300 NSv proximity probe and an extension cable. Operators can easily integrate this unit into control systems like PLCs or DCS networks for continuous asset oversight.
Technical Specifications
First, the device operates on a power input ranging from +12 to +35 Vdc at the terminal. It outputs a reliable 4 to 20 mAdc signal over a specified full-scale range using a convenient 2-wire configuration. Additionally, the loop accuracy remains within ±1.5% across the entire full-scale measurement range.
Meanwhile, the unit features a typical current limiting capability of 23 mA to protect your industrial electrical circuits. Regarding electrical limits, the maximum loop resistance reaches 1,000 Ω when operating at 35 Vdc with the cable included. Furthermore, the system delivers an impressive frequency response from 5 Hz to 6,000 Hz for dynamic machinery vibration tracking.
To ensure optimal performance, technicians must gap the companion probe between 0.5 and 1.75 mm from the target. For instance, maintaining this precise distance guarantees that the sensor utilizes its entire full-scale option of 0 to 10 mils pp. Moreover, the observed target must meet a minimum size requirement of 9.5 mm in diameter for accurate readings.
This robust transmitter features a compact design, weighing approximately 0.43 kg without its optional hardware and shipping packaging. For the physical interface, the maximum cable distance for the Proximitor sensor output via the BNC connector is 3 meters. Ultimately, the engineering layout allows for reliable operation in non-hazardous areas as well as Zone 2 or Division 2 environments.
Technicians can install the device quickly by utilizing the integrated 35 mm DIN rail clips. First, snap the transmitter securely onto a standard DIN rail inside your industrial enclosure or junction box. Next, connect the 3300 NSv proximity probe and the corresponding 7.0-meter extension cable to the input terminal. Finally, adjust the non-interacting external zero and span controls to calibrate the device without affecting other signal settings.
