Surface Voltage Logging System PT-SVLS

TOP > English TOP > Our Products > Surface Voltage Logging System PT-SVLS

Enables surface voltage measurement during E-Coat operation

PT-SVLS is an easy-to-use surface voltage logger system with a rugged enclosure and reliable measurement accuracy.

Providing visibility on the target surface, it is ideal for trouble shooting and evaluating the coating process of a new target.

Features of PT-SVLS

  • Easy Setup 
    The simple design allows for operation right out of the box, complete with quick setup and easy node placement.
  • Leak-proof Enclosure Sealing 
    Since this logger system usually is submerged in the E-Coat tank with the target, sealing is crucial. The ferule clamp structure provides a leak-proof seal.
  • Easy Enclosure Cleaning
    A special coating is applied to the enclosure which allows for easy cleaning of the E-Coat paint.
  • 8 Probes
    The system has 8 probes to allow for multiple locations to be evaluated during a single test run.
  • Easy Probe Placement
    Each probe has a magnet, allowing for easy placement on the target.

  • Try it before purchasing
    For the customers who are interested, we lone out a system for pre-purchase evaluation.

How it works

hisep_principle_of_operation.png
The sensor is placed on the target's area in question, and the system logs the surface voltage after it is divided by 1/1000 via the voltage divider unit. 
ex: If the surface voltage is 300V, the voltage at the logger terminal is 0.3V.
Sampling Rate (default): every 1 second

Reading in the data

● The measurement data is stored in the CF card of the logger system.
● The Data format is CSV, allowing easy data import using spreadsheet software (when the data format is changed to binary, the sampling rate can be increased to 10ms; however, it requres logger manufacturer's software for viewing/processing).
