Description

The Conducont LP4 conductivity sensor is an electronic conductivity transmitter for monitoring, controlling and continuously measuring conductivity and temperatures in liquids.

The Conducont LP4 conductivity sensor is suitable for conductivity measurement applications in almost all industrial sectors, especially for fresh, waste and salt water. The narrow design allows it to be used in confined installation conditions, e.g. in small-diameter dip pipes.

The high-precision, long-term stable and robust conductivity measuring cell, the stainless steel housing and the thick-walled, length-stable carrying cable with heavy-duty steel core ensure reliably precise measured values and enable operation even under demanding environmental conditions, e.g. low temperatures, high shock and vibration loads or problematic liquids.

A 4-electrode cell is used to measure the conductivity, which ensures accurate and reliable temperature-compensated measurement over a wide conductivity range, even in the case of contamination.

An integrated, long-term stable platinum temperature sensor is used to measure the temperature.
The measured temperature value can be read out via the digital interface in the RS485 Modbus-RTU version.Zur Messung der Temperatur wird ein integrierter langzeitstabiler Platin-Temperatursensor verwendet.
Der gemessene Temperaturwert kann bei der Ausführung RS485 Modbus-RTU per Digitalschnittstelle ausgelesen werden.

Parameterisation and operation can be carried out via the integrated wired interface.
