Frequently Asked Questions
Q: What's the key advantage of ATEX certification?
A: Safe operation in flammable atmospheres where standard sensors would pose explosion risk
Q: Difference between 5/8-18 UNF and metric threads?
A: UNF is Unified National Fine thread (imperial) vs metric M10/M12 in other models
Q: Suitable for marine environments?
A: Yes - DNV certified and 316L stainless construction
Q: Can I use regular instrumentation cable?
A: Requires low-capacitance cable (max 200pF/m) for optimal performance
Q: Vibration measurement direction?
A: Axial sensitivity - motion along sensor axis
