Ordering Code Breakdown

• 330704 = 3300 XL 11 mm Probe, M14 x 1.5 thread, with armor
• 000 = Unthreaded length 00 mm
• 050 = Overall case length 50 mm
• 10 = Total length 1.0 metre (3.3 feet)
• 02 = Miniature coaxial ClickLoc connector, standard cable

Temperature Classification (EPL Ga/Gc)

• T1: -55°C to +232°C
• T2: -55°C to +177°C
• T3: -55°C to +120°C
• T4: -55°C to +80°C
• T5: -55°C to +40°C

Installation Guide

• Use M14x1.5 mating thread.
• Apply 21.1 N•m recommended torque. Do not exceed 63.3 N•m.
• Keep thread engagement within 21 mm max.
• Avoid exposing probe below -34°C before use. This prevents pressure seal damage.
• Match with 3300 XL driver for best performance.

FAQ – Frequently Asked Questions

• What is the standard cable length for this model?
• Total length is 1.0 metre (3.3 feet). Option 10 means 1 meter.
• Can I use this probe with a 3300 XL 5 mm driver?
• No. Use only 3300 XL 11 mm driver for correct linearity.
• What happens if I over-torque the probe?
• Over-torque above 63.3 N•m can damage threads or case.
• Why does the probe show higher output in magnetic fields at larger gaps?
• At 4.6 mm gap, interference is 0.027 V/Gauss. Keep gap below 2.5 mm for best noise immunity.
• Can I cut and splice the probe cable?
• No. Cutting changes 75 Ω impedance and ruins accuracy.
• How do I store spare probes?
• Store at room temperature, away from solvents. Keep protective cap on tip.
• Do you have stock for 5 meter or 9 meter versions?
• This listing is for 1 meter. Contact us for longer lengths.

Selection Guide – How to Order Right

• Step 1: Choose unthreaded length. 000 = 00 mm for most standard holders.
• Step 2: Select case length. 050 = 50 mm fits deep mountings.
• Step 3: Pick total probe length. 10 = 1 meter for short runs. Use 5 or 9 meters for long distance.
• Step 4: Connector 02 (ClickLoc) is best for quick changes. Avoid 03 for high vibration.
• Step 5: Approval 05 (multiple) is recommended for global use. Choose 00 for domestic only.
• Pro tip: For ambient temperature above 120°C, select T1 or T2 classification. Below -40°C, verify cable flexibility.
