Dew point Transmitter 

The Vasthi V smart Tdx series Dew Point Transmitter is ideal for continuous dew point measurement.

Precise dew guide estimation down to -60°C Td (-76°F Td).

Utilizes microprocessor circuitry to convert sensor signals using psychometric equations.

Assembled in a rugged handheld IP-65 body with quick disconnect tubing couplings.

Internal sensor manifold.

Dedicated input to maintain line pressure.

Powerful metal encasing (Aluminum or Treated steel)

RS485 interface (Modbus RTU)



  • Analog output 4-20 mA for dew point
  • Condensation insensitive
  • Fast adjustment time
  • Pressure resistant up to 350 bar (special version)
  • RS485 RTU interface
  • The higher resolution of the sensor signal history graphical data
  • Sensor diagnosis is on-site with a mobile device.
  • Readable via Modbus:
  • Pressure dew point [°Ctd.]
  • Temperature [° C]
  • Rel. humidity [% RH]
  • Moisture content V / V [ppmV / V]


Q. Can we fit the transmitter directly into the pipeline?

A. Yes, you can.
