Precise gap voltage validation at -24 VDC targets is maintained to ensure the transducer operates within the linear range. The monitor handles rotor dynamics data by applying a 0.09 Hz 1-pole low-pass bias filter to incoming signals, effectively suppressing noise while retaining phase information. Cross-talk suppression is managed through high-input impedance (10 kOhm for 3-wire voltage mode) and dedicated channel isolation, ensuring signal integrity across multiple speed and vibration measurement inputs.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x 1900\/65 167707-01 Equipment Monitor unit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Terminal block set for sensor and power connections.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e1 x Installation and technical reference documentation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eField Installation Procedures\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eMounting and Grounding\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eSecure the monitor unit to a flat, grounded panel surface using the provided mounting holes to ensure thermal heat dissipation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnect the chassis ground to the cabinet common to minimize EMI and protect the monitor against potential voltage surges.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003eSignal Wiring\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eEnsure all sensor cables are shielded and that shields are grounded at the monitor end only to prevent ground loops.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eKeep vibration signal cabling physically separated from high-voltage AC power lines to maintain input signal quality.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eDoes this monitor support hot-swapping?\u003c\/p\u003e\n\u003cp\u003eThe 1900\/65 is designed as a fixed-mount unit; while sensor inputs can be disconnected during operation, the module itself is not intended for hot-swap operations within a live power environment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is the bias voltage set?\u003c\/p\u003e\n\u003cp\u003eThe monitor provides a fixed -24 V bias for standard proximity probes, which is verified by checking the gap voltage at the sensor input terminal block.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the role of the 2.4 kHz OK filter?\u003c\/p\u003e\n\u003cp\u003eThe 2.4 kHz 1-pole low-pass OK filter is used to monitor the signal path health; if the signal exceeds this frequency, the monitor registers an OK fault condition.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan it handle 4 speed measurements simultaneously?\u003c\/p\u003e\n\u003cp\u003eYes, the monitor is architected to process up to 4 distinct speed measurements concurrently using standard pulse-type inputs.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIs the speed accuracy dependent on the rpm range?\u003c\/p\u003e\n\u003cp\u003eThe speed accuracy is defined as +\/- 0.5 rpm plus 0.015% of the reading, ensuring linearity across the 100 to 100,000 rpm measurement spectrum.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow are vibration variables calculated?\u003c\/p\u003e\n\u003cp\u003eVibration inputs are conditioned and scaled relative to the full-scale range, with an accuracy of +\/- 1%, which is consistent across all standard monitoring channels.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDoes the monitor require software for configuration?\u003c\/p\u003e\n\u003cp\u003eThe monitor is configured via a dedicated serial interface using manufacturer-specified software to define alarm setpoints and sensor scaling.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eCan I use this for TSI (Turbine Supervisory Instrumentation)?\u003c\/p\u003e\n\u003cp\u003eThis monitor is primarily designated for \"General Purpose\" equipment; while capable of high-speed monitoring, it lacks the specific feature sets required for complex TSI turbine protection.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":46026831462573,"sku":"167707-01","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/190065A3.jpg?v=1782786489","url":"https:\/\/www.maxwellplc.com\/ru\/products\/1900-65-167707-01-bently-nevada-1900-series-general-purpose-equipment-monitor","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
