BM Engineering Supplies offers a wide range of pH, ORP and conductivity transmitters from Bürkert – one of the world’s leading manufacturers of measurement and control systems for liquids and gases. Here is a selection of just some of the Bürkert products that we offer.
Conductivity Transmitters Types
Bürkert Type 8285
The 8285 modular process analysis system is designed to measure and process liquid analysis parameters. The base unit contents the power supply, signal outputs, binary inputs and the front with backlit graphic display. Three slots are available, which depending on the applications can be occupied with modules for pH, conductivity or also with a module with additional outputs.
The hygienic, polished stainless steel enclosure version allows application in the field of bio technology, food processing and in the pharmaceutical industry. Further applications in the chemical industry, environmental engineering, water and waste-water treatment and in power plants are also possible.
Bürkert Type 8222
The Bürkert transmitter Type 8222 is a compact device designed for measuring the conductivity of fluids. The transmitter consists of a sensor, plugged in and pinned to an enclosure with cover containing the electronic module and a removable display. The sensor comprises a cell with two electrodes and a Pt1000 temperature probe.
The sensor itself is available with three different cell constants C. Those with C=0.01 or 0.1 are fitted with stainless steel electrodes and those with C=1.0 are fitted with graphite electrodes. The conductivity transmitter can operate independent of the display but it will be required for programming the transmitter (i.e. selection of sensor cell constant, language, measuring range, engineering units, calibration…) and also for visualizing continuously the measured and processed data.
The Type 8222 is available with three fully programmable outputs: two transistor and one 2-wire 4-20 mA current outputs, as well as four fully programmable outputs: two transistor and two 3-wire 4-20 mA current outputs. The electronics of Type 8222 converts the measured signal, displays different values in different physical units (if display mounted) and computes the output signals, which are provided via one or two M12 fixed connectors.
Yes, but it all depends on the liquid being measured. The mobility of the ions in your chosen solution increases as the temperature of a solution increases, therefore leading to an increase in its conductivity. Thus, it is advised to associate conductivity measurements with a reference temperature, which is generally 20 ºC or 25 ºC.
No, all substances house some conductive properties. Normally, organic compounds have very low conductivity, whereas metals have very high conductivity.
