The internal crystal generates charge proportional to casing vibration, conditioned into a 4-20 mA output. Signal integrity depends on shield grounding at the monitoring end only. The two-wire current loop topology suppresses induced voltage noise on long cable runs. Gap voltage validation does not apply to this transmitter. Frequency response is factory-set and not field-adjustable.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003eQ: What is the maximum loop resistance?\u003cbr\u003e\nA: At 24 VDC, typically 600 ohms. Total cable and receiver resistance must not exceed the limit derived from supply voltage.\u003c\/p\u003e\n\n\u003cp\u003eQ: Is the 177230-01-01-05 hot-swappable?\u003cbr\u003e\nA: No. Disconnecting it interrupts the current loop and causes a fault reading. Place the channel in bypass before removal.\u003c\/p\u003e\n\n\u003cp\u003eQ: Can it work with any 4-20 mA system?\u003cbr\u003e\nA: Yes, if the receiver supplies 12-30 VDC and accepts 4-20 mA. It does not support HART.\u003c\/p\u003e\n\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\n\u003cp\u003eMount directly on the machine casing with a stud or rigid bracket. Ensure flat metal-to-metal contact; avoid paint or gaskets. Route the two-wire cable away from high-voltage conductors. Use twisted-pair shielded cable with the shield terminated only at the monitoring end. For IP65 integrity, use a cable gland with proper thread engagement; NPT threads require a minimum of 5 engaged threads. Verify loop current with a milliammeter before connecting to the monitoring card. Do not exceed -40 deg C to 85 deg C at the mounting location.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":52903370522756,"sku":"177230-01-01-05","price":166.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/177230-01-01-05-1.jpg?v=1790309332","url":"https:\/\/www.etowonauto.com\/products\/177230-01-01-05-bently-nevada-seismic-transmitter-original","provider":"Etowon Auto","version":"1.0","type":"link"}
