Filters, pumps, and regulators can be incorporated to deliver the sample in an accurate condition. Bypass flow systems enable longer distances from the process to the analyzer to be achieved. Our engineers at Vasthi Instruments are always ready to recommend the right system for you on receipt of the full gas stream specification.

What is the dew point temperature?

Dew point temperature is simply the temperature at which water vapor in the air mass condenses into a liquid state, hence creating dew drops in the compressed chambers. The dew point temperature is a unit system for measuring the moisture (PPM) level present in a gas. Dew point temperatures may vary depending on the barometric pressure in the compressor outlets. In other words, a dew point is a temperature at which water vapor turns into water droplets. thus causing damage to the equipment. Dew points can vary between ambient temperatures to - 80°C (- 112°F) depending on specialized applications.

What is the Pressure Dew Point?

The dew point temperature of air or gases at a pressure higher than atmospheric pressure can be termed as pressure dew point (PDP). The pressure dew point depends on the final compression pressure in the chamber. In case of a declining pressure, the pressure dew point drops. Pressure dew point is significant for compressed air only.

Why dew point measurement is essential?

Temperatures in compressed air chambers can often rise up to 148°C (300°F). If proper cooling procedures are not implemented, excessive temperatures can damage equipment, compromise the product, and even become hazardous for employees. Maintaining a predisposed temperature in pressurized chambers is highly important to achieve the best output. Dew point measurements play a vital role in the safe operation of devices and systems. Failing to maintain an optimal dew point results in malfunction of control instruments, inconsistent operation of air valves and cylinders in the systems, and often increases wear and maintenance of pneumatic devices. Dew point measurement is a significant factor in HVAC (Heating, Venting, Air conditioning). It is a major factor in determining possible deterioration in metals, and in various chemical manufacturing operations. Using a dew point transmitter for continuous monitoring of dew temperature is recommended. Since dew points play a crucial role in a vast number of processes, precise dew point measurement tools have become a primary utility in everyday industrial functions.
