• Connector Type: Miniature coaxial ClickLoc™ connector with standard cable.
• Agency Approvals: Includes CSA, ATEX, and IECEx certifications for explosive atmospheres (option 05).

Installation & Mounting Instructions

• Apply the recommended torque of 11.2 N•m (100 in•lbf) for standard forward mount probe cases.
• Do not exceed 0.563 inch of thread engagement for the 3/8-24 UNF case thread.
• Set the gap for radial vibration measurements to -9 Vdc (approximately 1.27 mm / 50 mils).
• Ensure the ambient temperature remains between -52°C and +177°C for standard operation.
• Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure.
• For ETR probes, the tip can withstand up to +218°C, and the cable up to +260°C.

Environmental & Compliance Details

• Temperature classifications (EPL Ga/Gc): T1 to T5 with ambient ranges from -55°C to +232°C.
• For EPL Dc, classifications include T280°C down to T90°C with specific Ta limits.
• The probe cable features a CableLoc design providing 330 N (75 lbf) pull strength.
• An optional FluidLoc cable option is available to prevent oil leakage through the cable.
• The 8 mm design offers thicker encapsulation, making it more rugged against physical abuse.
