- For in-line or immersion measurements
| Probe connection: | 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. The cable must be of one length between the probe and the indicator without intermediate junction box. |
| Cable for temperature measurement: | For temperature, cable should be 3-wire type and shielded (3 x 0.22 mm²). The shield is connected to ground only on one end. Probes with a Pt100 built-in sensor have 2 specific cable-glands, insuring a perfect water-tightness. |
BAMO BS-BC probes are designed for conductivity measurements (0.05 to 10 μS/cm) or resistivity (10 kΩ.cm to 30 MΩ.cm, on water. It can be used for controls of rainwater or runoff, controls on demineralized water in industrial process such as soilers monitoring, parts rinsing in galvanic process and electronic components rinsing.
The external frame of the probe 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.
The cell factor is the ratio between the measurement done with the cell and 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.
