BCT100

Conductivity Cell with built in 4-20mA Transmitter

conductivity cell with built-in 4-20mA conductivity transmitter

The BCT100 is a conductivity cell with a built in 4-20mA transmitter.  The electronics are integrated into the housing, which means that a separate Conductivity Transmitter isn't required. The BCT100 can be connected directly to a PLC, online Data Logger, or to a controller mounted further away.


4-20mA Toroidal or Inductive Conductivity Transmitter

The BCT100 is a toroidal conductivity transmitter, also known as a blind electrodeless transmitter or an inductive conductivity transmitter. There is some more information about how these work on our Toroidal Conductivity Transmitter product page.

Effectively these are great at measuring electrolytic conductivity values in the higher ranges as the principle of operation is to stimulate ionic activity which is then measured. In addition, as the measuring coils of the conductivity cell are not in direct contact with the solution, they are non-fouling in solutions with higher conductivities.


BCT100 Conductivity Measuring Ranges

The BCT100 has a fixed conductivity measuring range from 0 - 100.0mS complete with integrated temperature compensation. We factory calibrate the BCT100 to this range, to ensure that installation into a process is as easy as possible. The BCT100 can simply be immersed into the solution to be measured, and then a 4-20mA output signal corresponding to the 0 - 100.0mS range across two wires can be measured.

The BCT100 is loop powered.  This means that the same two wires which power the device also carry the corresponding signal back to the receiving instrument. The 4-20mA output is galvanically isolated to 600Ω which means that integrating the device into a PLC, digital Chart Recorder or an online Data Logger is simple and straightforward.


BCT100 Features and Benefits

The BCT100 is manufactured in cPVC to offer good chemical resistance and an operating temperature range of 0-50ºC with a pressure of 3 Bar at 20ºC. We also offer the BCT in PVDF for greater chemical resistance and a higher operating temperature.

The BCT100 is supplied complete with 3 metres of connecting cable as standard.  We can offer longer cable lengths up to 1000m, as required.

The conductivity cell with integrated electronics can be mounted into a number of different environments. There is a rear mounted 11/2" mounting thread designed so that the BCT100 can be immersed into vessels and tanks.  This is also known as Dip mounting.

In addition the BCT100 has a 11/2" thread located at the front of the conductivity cell allowing the BCT100 to be mounted directly inline into pipe work for continuous online conductivity measurements.


BCT100 Conductivity Transmitter Applications

As a conductivity cell with a built in 4-20mA transmitter, the BCT100 works well integrating with PLC's for systems controlling external processes. The cPVC body, automatic temperature compensation and range of 0 - 100.0mS often means that the BCT100 is found in CIP applications as well as in solution strength control applications for both Acid and Alkali processes.

The BCT100 is a simple to use toroidal conductivity cell with integrated 4-20mA transmitter to offer accurate hassle free measurements, and to integrate as a 2 wire device.
