The compact HLX355 dew point transmitter

Dew point sensor / transmitter for industrial drying processes

The compact HLX355 dew point transmitter with a measuring range down to -60 °C (-76 °F) Td and outstanding price/performance ratio is dedicated for applications in compressed air systems, plastic dryers and industrial drying processes..

An integrated auto-calibration procedure leads to accuracy of ±2 °C (±3.6 °F) Td. The measured values for dew point, frost point or ppm volume concentration are available on an analog 4-20 mA and a digital Modbus RTU output. Integration into the measurement task is simplified by the compact design and the exceptionally robust stainless steel enclosure.
With an optional Modbus to USB convertor and the free HLX-PCS configuration software the user can adjust the dew point transmitter, set the Modbus parameters, and change the scaling of the analogue output.
