PRACTICAL Control Solutions has released the Jumo CTI-500 conductivity and temperature transmitters, using an inductive measurement technique to provide virtually maintenance-free measurement of temperature-corrected conductivity from 0μS/cm-500μS/cm to 0mS/cm-2000mS/cm.
The temperature measurement range is from 0°C to 150°C with a fast-response in-stream stainless steel probe and an internal, slower-response probe option that does not come in contact with the liquid.
The transmitters can be programmed from a lockable membrane front panel or via a PC or notebook. Versions with or without displays are available.
The instruments are suited to CIP processes and applications involving gypsum/lime precipitates, grease and oil, and corrosive media. They are pre-programmed to indicate concentration of nitric acid and caustic soda. Other solutes can be measured using a freely-programmable, up-to-20 point calibration curve.
The JUMO CTI-500 series is available as an integrated sensor-transmitter or as a transmitter with a remote-mounted sensor. Transmitter outputs for temperature and conductivity are selectable from 0V-10V, 0mA-20mA, 2V-10V, 4mA-20mA or the inverse 10V-0V. Solid state relays provide logic outputs for min/max limit conditions. The instruments require connection to a dc supply in the range of 19V to 31V.
