III. Installation Tips

1. Length ratio strictly follows the total length of the probe cable plus the extension cable, consistent with the rated length of the preamplifier

2. Avoid oil stains and dust on the connectors, wear a protective cap during idle periods

3. Segment the cables for fixation, keep away from high-temperature and high-pressure pipelines, avoid hard bending and pulling

4. Shield layer is only grounded on one side of the preamplifier, avoiding circulating interference signals

IV. Comparison of Same Specifications Models

330930-065-00-00: Without armor and explosion-proof, for normal ordinary conditions

330930-065-01-00: With armor protection, wear-resistant and durable, not for explosion-proof environments

330930-065-05-05: Armor with explosion-proof certification, suitable for hazardous areas

V. Common Faults

Signal interruption: Check the firmness of connector insertion, damage or breakage of cable outer skin

Value fluctuation: Check the grounding method, keep away from high-power electrical equipment

Transmission anomaly: Verify if the total length of the entire cable matches the parameters of the preamplifier
