Industrial High Pressure Dew Point Transmitter DPPT-HP

Industrial High Pressure Dew Point Transmitter
Model: DPPT-HP

Introduction
DPPT-HP industrial dew point transmitter is used to measure ambient and dew point temperature with stainless steel filter or mesh. DPPT-HP is suitable for compressed air systems, refrigerators, adsorption machines, plastic dryers, paper, chemical process monitoring, etc.

Features
■ 2-in-1 output - combined analog and digital output in one design
■ RS485－supports floating-point and integral point, metric and imperial unit
■ PNP alarm output available
■ Dew point units and corresponding value are adjustable for analog output type
■ Full range temperature compensation, Accuracy±2℃ Td (@-40⋯60℃Td)
■ Long-term stability with fast response to ambient change
■ Max. ambient temperature 85℃, Max. pressure resistance 100bar
