Bamo BS – BC Conductivity and Resistivity Probes

Bamo BS – BC Conductivity and Resistivity Probes

Bamo BS – BC Conductivity and Resistivity Probes the external frame surrounds the active part (centric electrode) and limit the measuring area used for measurement, ensuring perfect shield grounding. Some models have a built-in temperature sensor (Pt100 type). For a high mechanical resistance, cells are in AISI 316 L with PTFE insulation.

Cell factor: The cell factor is the ratio between the measurement done with the cell and the value displayed on the monitor.

Example: A probe with a cell factor K = 0.1 immersed in a liquid of resistivity 10 kΩ.cm, measures a resistor value of 1 kΩ. The monitor will display a corrected value by factor K: resistivity of 10 kΩ.cm.

For highly conductive liquids (low resistivity) it will be necessary to use probes with cell factor of K=1 or K=10 or inductive sensors.

Complete Measuring System:

  • A complete system includes: 1 Coaxial probe with K = 0.01 or K = 0.1
  • 1 Connector PL259 or direct connection to screw connectors or cable output
  • Coaxial cable CCA type
  • A 3-wire cable C3B type (when Pt 100 sensor is built-in the probe)
  • One BNC plug for monitor connection.
  • A monitor BAMOPHAR 323.

Bamo BS – BC Conductivity and Resistivity Probes Specification

Electric connection is done as following, according to probe model:
    With a removable coaxial connector PL 259 type.
    With integrated screw terminals for industrial heads.
    With cable (cable output probes).
    With a BNC plug.
Cable For Conductivity
It transfers the signal between probe and BAMOPHAR.
A cable of a bad quality may procure errors over 50 %. The specific cable CCA is a safe solution, 100 % compatibility with our probes BS-BC.
In parallel, some probes have a cable output
Connector on the monitor:
A coaxial plug BNC is necessary to connect with the BAMOPHAR monitor. A standard connector or electric cable will induce errors on measurements, even on a short distance.
