Features & Benefits

• Robust 4-20mA Output: Standard industrial signal allows long-distance transmission and easy connection to PLCs, DCS, and SCADA systems without additional signal conditioners.
• Extreme Environment Rated: Wide temperature range (-55°C to +125°C) and IP68 submersible rating make it suitable for the harshest applications, including offshore and outdoor installations.
• High Accuracy: Excellent linearity (±1%) and low phase shift ensure reliable data for condition monitoring and machinery protection.

FAQ

• Q: What does the PR9268/202-100 sensor measure?
  A: It measures vibration velocity (how fast a surface is moving back and forth) in mm/s, which is a key parameter for assessing overall machine health and ISO vibration severity.
• Q: What is the advantage of a 4-20mA output?
  A> It is highly resistant to electrical noise, allows for long cable runs without signal degradation, and is the universal standard for process instrumentation, simplifying system integration.
• Q: What does IP68 rating mean for installation?
  A: IP68 means the sensor is dust-tight and can be continuously submerged in water under specified conditions (up to 10 meters depth), offering maximum protection against harsh environments.
