3-in-1 Dewpoint, Pressure, Temperature Transmitter for SF6 Gas

The Vaisala Multiparameter Transmitter DPT145 for SF6 Gas is a unique innovation that enables online measurement of dew point, pressure, and temperature. It also calculates four other values, including SF6 density. The DPT145 is especially well suited for integration into OEM systems.

DPT145 Overview

- First transmitter to offer online measurement of seven SF6 parameters in one unit

- Measured parameters: dew point, pressure, temperature

- Calculated parameters: SF6 density, normalized pressure, dew point in atmospheric pressure, ppm

- Saves time and money across the board, from investment and installation to operation and servicing

- More reliable assessment of the condition of SF6 insulation due to online measurement

- Long calibration interval of years

Dew Point Meter for Refrigerant Dryers

Vaisala HUMICAP® Dewpoint Transmitter DMT132 is an affordable dew point measurement instrument designed to verify the functionality of refrigerant dryers. The probe has excellent long-term stability and it is resistant to compressor oil. It is especially well suited for OEM dryer manufacturers.

Dew Point Transmitter for Very Dry Environment

The Vaisala DRYCAP® Dewpoint Transmitter DMT152 is designed for measuring low dew point in OEM applications, even down to -80°C. The excellent long-term stability and reliability of its performance is based on the latest DRYCAP® polymer sensor technology. The DMT152 is an ideal choice for industrial applications where it is necessary to control very low humidity. DMT152 is an ideal choice for the semiconductor industry, air and plastics dryers, glove boxes, dry chambers, pure gases, additive manufacturing, high voltage circuit breakers and other applications where it is critical to control humidity with high accuracy. he DMT152 measures accurately and reliably also in the challenging combination of low humidity and hot air, which is typical in plastics drying.

 

Dew Point Transmitters for High Temperature Applications

The Vaisala DRYCAP® Dewpoint Transmitters DMT345 and DMT346 are designed for humidity measurement in industrial drying applications with particularly high temperatures. The high temperature tolerance of the sensor allows direct measurement from hot process without the need for a sampling system and sample conditioning. The wide dynamic rage of the measurement in DMT345 and DMT346 is unique: Measurements can be made from -40 °C frost point up to +100 °C dew point, with dry-bulb temperatures ranging up to 350 °C.

Dewpoint And Pressure Transmitter For Compressed Air

The Vaisala Dewpoint and Pressure Transmitter DPT146 for Compressed Air makes monitoring compressed air simple and convenient. The DPT146 measures both dew point and process pressure simultaneously, and is the ideal choice for anyone using or monitoring compressed air.
