Description

The CDTX441 conductance/resistance analyzer is designed for online monitoring of process solutions and water applications. Applications include: waste water treatment, power plants, thermo electric plants, pharmaceutical, photographic industries and soft drinks industries. The menus are self guiding with simple three button programming. The transmitter output is also programmable from the keypad eliminating the need for potentiometer or dip-switch settings. The calibration function automatically recognizes the cell used and the buffer solution resulting in a simple and straight forward system calibration. Tough body construction in cast aluminum, finished with electrostatic epoxy paint. The enclosure has an IP68 (NEMA 7X) rating and Intrinsically Safe electronics inside. The 4 to 20 mA analog output has galvanic isolation of 2000 Vac (by opto coupler) and line resistance of 50Ω. The meter can be installed on a flat surface or on a 51 mm (2") tube.
