Configuration
- Zero Unthreaded Base: Configures a 0.0-inch unthreaded length to maximize the usable threaded engagement area along the sensor body.
- Two-Inch Case Profile: Allocates a 2.0-inch overall case length utilizing standard 1/4-28 UNF-2A mounting threads for straightforward panel tapping.
- One-Meter Cable Length: Deploys an integrated 1.0-meter 75-ohm triaxial FEP-insulated leading cable ended with a gold-plated ClickLoc connector.
- Multi-Approval Rating: Locks in certified intrinsic safety and non-incendive parameters matching global ATEX, IECEx, and CSA installation standards.
Features and Benefits
- Optimized Packaging Footprint: Provides the exact same 2.0 mm (80 mils) linear range as larger 8mm probes while reducing the physical package size for constrained areas like thrust bearing pads.
- Patented TipLoc Construction: Employs a specialized molding method that establishes a highly robust structural bond between the PPS tip and stainless steel body.
- Interchangeable System Design: Eliminates custom bench calibrations or component-matching efforts through absolute interchangeability across matching cables and sensors.
- Tool-Free Quick Connection: Utilizes a gold-plated brass ClickLoc connector mechanism engineered to lock finger-tight and resist operational loosening.
- Wide Thermal Stabilization: Maintains a stable signal output over a wide field landscape spanning temperatures from -35°C to 177°C (-31°F to 351°F).
Installation & Troubleshooting FAQ
Q1: When should I choose this 5mm probe version over a standard 3300 XL 8mm probe assembly?
A: This 5mm probe should be utilized strictly when physical, non-electrical layout limitations completely rule out an 8mm probe, such as tight spaces between thrust bearing pads. Because the 8mm alternative houses a thicker PPS tip encapsulation and a larger diameter case, it is significantly more rugged against physical abuse. Whenever physical panel clearances permit, the 8mm probe remains the primary recommendation.
Q2: Does the smaller physical size of this 5mm tip allow me to decrease my counterbore or tip-to-tip clearances?
A: No, the 5mm probe does not reduce sideview clearance boundaries or tip-to-tip spacing requirements compared to an 8mm probe. To avoid side-effect errors and cross-talk, maintain a minimum center-to-center distance of 40 mm (1.6 in) for axial alignments and 38 mm (1.5 in) for radial layouts. Disregarding these boundaries or mounting on shafts smaller than 76.2 mm (3 in) will distort your scale factor.
Q3: Why is my loop reporting a diminished linear range, and what torque limits protect this case?
A: First, check your input supply line; the system demands a stable voltage between -17.5 VDC and -26 VDC, and operating more positive than -23.5 VDC restricts the linear window. Second, check for physical binding or over-torque damage. When installing this 1/4-28 case, the maximum thread engagement length is 0.375 inches, and the case installation torque must be kept near the recommended 5.1 N·m (45 in·lb) without exceeding 7.3 N·m (65 in·lb).
