Does the PR6423\/002-030 require a specific driver?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. To form a complete measurement loop, you must pair the PR6423\/002-030 with an Emerson\/EPRO CON021 or CON041 driver and the appropriate extension cable. The driver translates the probe's impedance changes into the standard voltage output required by the monitor.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.

While the probe will detect non-ferrous materials like aluminum or stainless steel, the sensitivity and linear range will differ significantly. Using this probe on non-ferrous materials requires custom calibration of the associated driver.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e3.
