HET63Electrodeless Conductivity Transmitters Features • Measurement of conductivity, % solution concentration, salinity and temperature • IP66 enclosure. • Wall mounting or head mounting versions • Detachable sensors on all variants for easy maintenance. • Up to two isolated 4-20mA current and two relay outputs. • Relays can be configured for on/off, time and pulse proportional control • Digital inputs for external range changing • Cable termination via detachable connectors, no need to open the enclosure • Low voltage operation 15-30v DC • Ideal for cooling tower bleed, rinse water and solution concentration applications • Preset curves stored for common chemicals and salinity • Custom curve from 2 to 9 points can be entered.

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 ECS20...
