Apply the specified mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) to ensure proper coupling. For best results, mount the sensor directly on the bearing housing or as close as possible to the bearing load zone. Ensure the mounting surface is clean and flat to avoid signal distortion.\u003c\/p\u003e\u003cp\u003eWire the sensor to the monitoring system with the correct polarity: SIG+ positive with respect to SIG-. The excitation voltage must be within 4.7 to 5.5 Vdc. After installation, verify the output bias voltage is +2.5 ± 0.23 Vdc and check the quiescent current is below 800 µA to confirm proper operation.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe hermetically sealed design protects the internal electronics from moisture and contamination, ensuring long-term reliability. With no moving parts, the accelerometer requires minimal maintenance. Periodically inspect the mounting stud for looseness and check the cable for damage. The operating temperature range of -40 °C to +105 °C allows use in extreme conditions. The 316L stainless steel housing resists corrosion, making it suitable for harsh industrial environments.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eWhen ordering, verify the part number 200157-21-05 matches your requirements. The mounting stud option 21 provides a 3\/8-24 to M6x1 adapter, ideal for installations requiring metric conversion. The approval code 05 ensures compliance with CSA, ATEX, and IECEx standards. For integration with the ProTIM option, select the standard acceleration-to-velocity with acceleration enveloping channel type (-06).\u003c\/p\u003e\u003cp\u003eFor dependable sourcing and fast delivery, choose PLC Source PRO as your automation parts supplier.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44438893887587,"sku":"200157-21-05","price":241.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/8635\/0435\/files\/200150-01-CN_6c702734-3e85-4765-bccb-795a46f22447.jpg?v=1785856086","url":"https:\/\/www.plcsourcepro.com\/ar\/products\/bently-nevada-200157-21-05-industrial-automation-module-stable","provider":"PLC Source PRO","version":"1.0","type":"link"}
