CONDUCTIVITY
Conductivity is commonly measured in various different applications.
Operating conditions for a conductivity analyser may be very different: for this reason we have developed a wide range of conductivity cells.
W can supply cells with platinum/glass electrodes suitable for laboratory applications, including through-flow cells for very small samples, cells with graphite electrodes and stainless steel electrodes for industrial applications, suitable for immersion and through flow installations, suitable for direct in process installation, in closed pipelines or vessels, also in high-temperature, high-pressure conditions.
The bodies are made of various materials, as Kynar, PES, Stainless Steel, PTFE etc. so suiting the most of the possible applications.
Cell constants are many: K = 0.01 cm, K = 0.1 cm, K = 1 cm, K = 10 cm, K = 100 cm so covering all typical measuring ranges.
We can also supply toroidal (inductive) conductivity sensors, suitable for high range measures and for the use in aggressive samples.
We supply instruments for the measure of conductivity for industrial applications, laboratory use and portable type.
We can supply process instrument suitable for panel mounting and for in-field installation (IP65 protection degree):
among these, the uP transmitter-indicator-controller is available in two versions: the complete version uP and the light version uPLT.
Main features for both units:
. local indication of measured parameter and process temperature,
. temperature compensation of the measure through dedicated algorithms,
. freely selsctable reference temperature for conductivity value
. cell constant automatic computation
. isolated 4-20 mA output (not available in the uPLT version),
. 4 programmable digital control outputs (2 for the uPLT version),
. self diagnostic and sensor diagnostic functionality,
. capability to drive the cleaning sequence for the sensor.
. freely programmable linearization curves
In the same family the PID controller, suitable for panel mounting and for in-field installation (IP65 protection degree), has the same features of the uP transmitter, and additionally allows PID process control either through contact control output or analog control output.
The line now includes a transmitter-controller with RS485 serial interface and MODBUS RTU communication protocol, Mod.TX and the Transmitter Indicator Controller c/w local keyboard and diplay Mod.TX-HMI.
Main features for these units:
. display indication of both analysis and temperature values (TX-HMI)
. automatic thermo compensation of the measure via software through specific algorithms
. freely selsctable reference temperature for conductivity value
. cell constant automatic computation
. RS 485 serial interface with MODBUS RTU communication protocol
. 2 analog output 420 mA for measure and tempertaure
. 2 digital outputs from relay, programmable
. 2 digital inputs, programmable
. remote calibration capability
. isolated 24 Vdc power supply; 24 Vac power supply
. suitable for rear panel mounting (DIN bar) and for outdoor installation (IP 65 protection degree)
. freely programmable linearization curves
