A mounting torque of 15 Nm (11.1 lb‑ft) ensures proper coupling. The sensor is fitted with a hermetically sealed integral cable (twisted pair, shielded) protected by a flexible stainless steel hose. Flying leads provide the electrical connection. No external charge amplifier is needed; the integrated electronics output a current-modulated 2‑wire signal suitable for direct connection to a monitoring system or galvanic separation unit.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eThe hermetically welded construction of the \u003cstrong\u003eVibro Meter 444-311-000-013\u003c\/strong\u003e makes it impervious to water, steam, oil, sea‑salt atmospheres, dust, and fungus. This eliminates the need for frequent recalibration or replacement. Factory dynamic calibration at 120 Hz and 5 g\u003csub\u003epeak\u003c\/sub\u003e (23°C) requires no subsequent calibration. To maximize service life, inspect the cable and protection tube periodically for physical damage; replace the assembly if the hermetic seal is compromised. The sensor’s robust design directly supports a cost‑benefit advantage by extending maintenance intervals and reducing spare‑part inventory.\u003c\/p\u003e\u003ch2\u003eSelection Guide and Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen ordering the \u003cstrong\u003eVibro Meter 444-311-000-013\u003c\/strong\u003e, specify the CE311 type with standard 3‑m integral cable. Verify your system’s input requirements: 15–28 VDC supply and a current‑modulated input (e.g., from a monitoring system or galvanic isolation unit). The sensor’s case insulation and long‑distance signal transmission (up to several hundred meters) simplify integration.
