61F-GP-N8

Features

Compact plug-in (8-pin) level controller

The 61F-GP-N8 can be used for single- or two-point level control of conductive materials, both liquids and solids. These products are equipped with a red LED operation indicator.

  • Low-voltage (AC) electrodes (8VAC or 24VAC)
  • Operation range: 4-15kΩ, 70-300kΩ
  • Detection method: conductive
  • Probes need to be ordered separately
  • Conforms to EMC and LVD directives, UL/CSA approved
