      190501 Velomitor CT Transducer

      190501-12-00-01

      Product Information:

      The 190501-12-00-01 is a Velomitor CT low-frequency velocity transducer specifically designed for monitoring casing vibration in low-speed rotating machinery. As a specialized low-frequency version of the piezoelectric velocity transducer, it is widely used for non-contact or absolute casing vibration measurements on fan assemblies—such as those found in cooling towers and air-cooled heat exchangers—that typically operate at speeds of 90 rpm or higher.

      PRODUCT & ORDER FAQS

      Questions buyers ask about 190501-12-00-01

      • How do I identify the exact 190501-12-00-01 configuration?

        The base model 190501 is the Bently Nevada Velomitor CT Velocity Transducer. In this specific configuration, -12 identifies the plate stud mounting hardware with a 3/8-in 24 to M8x1 interface, -00 specifies the MIL-C-5015 connection interface, and -01 specifies the multiple-agency approval configuration. This coding should be checked when replacing an existing sensor because different mounting and connection options are available within the 190501 family.

      • Can this sensor be connected to my existing vibration monitoring system?

        The 190501-12-00-01 provides an analog vibration-velocity output with a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% and uses a 2-pin MIL-C-5015 interface, making it suitable for integration with compatible vibration monitoring equipment. Bently Nevada specifies cable runs up to 305 m (1,000 ft) without signal degradation when the specified cable arrangement is used.

      • What type of machinery is the Velomitor CT intended to monitor?

        This model is specifically designed for low-frequency casing vibration measurement on cooling towers and air-cooled heat-exchanger fan assemblies operating at or above 90 rpm, with typical operating speeds of approximately 100–300 rpm. Its frequency response is shifted toward the low-frequency range, allowing it to measure vibration associated with the fan as well as vibration generated by the fan motor and speed reducer.

      • What should be checked when mounting the 190501-12-00-01?

        The -12 mounting option is important because it provides the plate-stud arrangement from 3/8-in 24 to M8x1. Bently Nevada specifies a 33 mm (1.3 in) mounting surface diameter and a mounting torque of 4.5 N·m ±0.6 N·m (40 in-lbf ±5 in-lbf); the manufacturer also emphasizes that incorrect installation can affect amplitude and frequency response or produce invalid vibration data.

      • Do you have the 190501-12-00-01 available as a new original item?

        Moore Automated supplies new, original products with a one-year warranty. For this particular Velomitor CT configuration, we can also provide available product photographs and the applicable technical documentation so the mounting, connector, and approval configuration can be checked before purchase.

      • Which certificates can be supplied with the order?

        Moore Automated can provide available COO, COC, test reports, calibration documentation, and warranty letters, depending on the product and documentation held for the shipment. For Bently Nevada products, available COO/DOC/COC and testing or calibration certificates can be checked in advance and, where available, included with the shipment.

      • Can you arrange delivery directly to our site?

        Yes. Moore Automated supports door-to-door delivery by DHL or FedEx, which can be arranged according to the destination and order requirements. If the sensor is needed for a maintenance replacement, we can also confirm the available stock status and shipment arrangement before the order is finalized.

      • Can you offer a better price, and are you an authorized Bently Nevada distributor?

        Moore Automated is not an authorized Bently Nevada agent, but we supply the same branded products and can check available discounts for the 190501-12-00-01. If you already have a target price, please send it to us; this allows us to apply for a more competitive quotation efficiently, and a special discount may be available if you are ready to purchase.
