| SMART WG-2 e. conductivity + °C |
Conductivity controller for conductance-temperature- measurement in a wall-mounted housing for on-site installation.
Conductivity plays an important role in many applications, e.g. in process control, in product or water monitoring or in the detection of leaks.
Our conductivity sensors can be used in combination with the process controller to measure the conductivity and temperature of high-purity water 0.01 µS / cm to concentrated acids 800 mS / cm.
2 control outputs ( relay ), which can be configured as limit value, pulse length controller, pulse frequency controller and alarm output and 2 analog outputs 0 (4) ...20 mA, which can be assigned to any measured value, provide the connection to further signal evaluation devices.
The industrial measuring/control device is designed for mounting on the wall or on a panel in a splash-proof wall-mounted housing 120 x 122 mm.
