Frequently Asked Questions
Q: What type of machines is this sensor used on?
A: It is ideal for turbines, compressors, pumps, and fans in oil & gas, power generation, and chemical plants.
Q: Can the cable be replaced if damaged?
A: No. The cable is permanently fixed (integral) to the hermetically sealed sensor. The entire unit must be replaced.
Q: What is the difference between “Ex ia” and “Ex d” certification?
A: “Ex ia” is an intrinsic safety rating for Zone 0/1 (high risk). “Ex d” is a flameproof enclosure rating, typically for Zone 1. This sensor is Ex ia.
Q: How do I mount this accelerometer correctly?
A: Clean the mounting surface. Use a stud or adhesive mount. Tighten to the specified torque to ensure good frequency response.
Q: From your experience, what is a key factor for sensor longevity?
A> Proper cable routing is critical. Use clamps and avoid sharp bends. Stress on the cable exit point is a common failure cause.
