Two different options of the HET63 transmitter are available with the base model offering a single industry standard 4-20mA output while the Advanced HET63 offers two 4-20mA outputs enabling the process temperature to be measured and transmitted as well as the conductivity or solution concentration value. The Advanced HET63 model also has three digital inputs for remote range changing via a plc. Both of the HET63 versions are available as head mounted transmitters mounted on an ECS64 Electrodeless conductivity sensor or as a wall-mounting version with a detachable cable and separate LTH...
