For a 25 mm system with a 500-mil range, the center of the linear region typically corresponds to -10.0 VDC. Adjust the probe position until the DC voltage at the Proximitor output reaches this value while the shaft is at its normal axial reference point.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDIN Rail Grounding and Isolation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Proximitor is designed to be mounted on a 35 mm DIN rail. To prevent ground loops and electromagnetic interference (EMI), ensure that the DIN rail itself is properly grounded. However, the coaxial cable shield must remain isolated from the machine ground and should only be tied to the system common at the Proximitor end. Use insulating washers or standoffs if the local environment is prone to high electrical noise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEnvironmental Protection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhile the Proximitor is rated for operation up to 85 deg C, it is a precision electronic instrument.
