Frequently Asked Questions
- Question: How does the sensor seal pressure?
Answer: The probe seals differential pressure using a Viton O-ring located between the tip and case. - Question: What cable type works best for field wiring?
Answer: Engineers should use a 3-conductor shielded triad cable for optimal noise rejection. - Question: Can this probe operate in hazardous locations?
Answer: Yes, the unit holds ATEX, IECEx, and CSA approvals for hazardous zones when paired with approved barriers. - Question: How do I select the right probe length for my machine?
Answer: Match the case thread and unthreaded length to your mounting bracket thickness and machinery clearance requirements.
