INOR CT20 Transmitter

The IPAQ CT20 is an analogue, PC-configurable transmitter for Pt100 sensors. This transmitter comes in a robust, IP67 casing with M12 connections in both ends and offers the highest levels of flexibility and reliability.

Easy installation and maintenance
The transmitters compact design and robust casing makes IPAQ CT20 the ideal choice for a wide range of applications, e.g. in OEM/Machine applications or integrated in production and process lines . The M12 connectors allows the IPAQ CT20 to be optimally installed based on environmental conditions, physical space and access for maintenance.

Easy configuration
The transmitters configuration is easily done before the installation with the user friendly ConSoft software and it can be configured and installed without stopping the process
