• System Accuracy: Maintains an accuracy of ±1.5% of the full-scale reading.
• Maximum Loop Resistance: Supports up to 1,000 Ω at a 35 VDC supply voltage.
• Frequency Response: Optimized for standard shaft vibration frequencies in rotating machinery.
• Operating Temperature: Designed to perform reliably across standard industrial temperature ranges.

Model Number Breakdown

• "04": Specifies the 0-4 mils peak-to-peak full-scale measurement range.
• "50": Indicates the unit comes with a fixed 5.0-meter (16.4 ft) sensor cable.
• "01": Denotes the inclusion of 35mm DIN rail mounting clips for easy installation.
• "05": This suffix confirms the critical hazardous area certifications: CSA Class I Division 2, ATEX Zone 0/2, and ABS Marine.

Installation & Setup Guide

• Securely mount the transmitter using the provided 35mm DIN rail clips.
• Install the compatible 3300 NSv proximity probe. Set the probe gap to 0.5 – 1.75 mm (20 – 70 mils) from the target shaft.
• Connect the wiring: apply +12 to +35 VDC power and loop the 4-20 mA output to your monitoring system.
• For optimal performance, use an extension cable not exceeding 3 meters in length.
