Data Acquisition & Telemetry


Conductivity and solution concentration transmitter

November 2006 Data Acquisition & Telemetry

LTH Electronics has designed a transmitter that sets new standards for the measurement of conductivity in various process applications such as dairy, brewing, food and process applications.

The one unit measures conductivity over the range of 500 μS/cm to 1000 mS/cm. Temperature is also measured to an accuracy of better than 0,2°C. The two measurements are combined within the transmitter and by using Windows software, the 4-20 mA outputs can be configured to measure in conductivity, % solution concentration, temperature, PPM or salinity.

Alternatively a standard RS485 interface provides controlled access to all of the configuration parameters and measurements on-line.

Operator confidence is boosted by showing the measured values and system status on the integral 3-line backlit LCD display.

The IET40 transmitter has been designed with various features such as IP66 stainless steel enclosure, peek detachable electrodeless conductivity sensor, steam sterilisable to 135°C (thermal shock resistant), fast temperature response t90<10 s, can be configured and calibrated before shipment, low cost connection cable, low voltage operation, simple installation, and a choice of sensor process connections.
