Red Dragon supplies a number of dew point sensors designed for measuring and monitoring the water content of gases in compressed air and gas systems where moisture can cause multiple problems and component failure.
In many different types of plant equipment using compressed air or gas systems moisture can cause contamination and corrosion and ultimately lead to failure of components.
Dew point instruments can be used to measure or monitor the water content of the air or gas. In this way system efficiency can be optimised, says the company, and the life span of the system and its different components effectively increased.
The dew point is the temperature at which the water vapour will start to condense out of a gas stream. With systems using compressed air, the dew point needs to be kept below the minimum ambient temperature.
This prevents liquid water that could lead to corrosion and breakage (and even icing up if the temperature falls low enough) from forming in pipework or components.
The dew point can also become a good indication of the general health of a compressed air or gas system and, in particular, the effectiveness of any installed dryer systems.
Dew point sensors for compressed air or gas determine the level of moisture/humidity in the flow. If an application requires the water content to be particularly low, then monitoring the dew point is vital.
Red Dragon, an independent specialist distributor of valves and instruments for process control and automation, supply a number of dew point sensors.
The CS-iTEC dew point sensor S 220 is designed to provide reliable and long-term stable dew point monitoring in a variety of industrial applications. The company adds that the instrument uses new sensor technology that supplies a superior signal at very low moisture levels and is reliable down to -100ºC. it also contains a stainless steel sinter filter to protect the sensor from particles.
Designed for a range of -50 to +20°C, the compact CS-iTEC S 212 dew point sensor is designed for a range of -50 to +20°C and is suitable for installation in tight environments and for desiccant dryers.
The S 201, designed to operate from -60 to +20°C, features a complete dew point meter with sensor, display, keyboard and alarm.
