The pressure dew point probes SE 26.4 and SE 26.20 HP with an integral thread of 3/4 inches are designed for monitoring the dew point of gases in pressure lines or pressure vessels. The constructional design with the integral thread guarantees a trouble- free assembly with the aid of conventional standard parts- e.g. directly into lines with a diameter of 3/4 inches or wider- without affecting the density.
Only the dew point sensor and the Peltier element are located in the overpressure area and are connected to the building components in the normal pressure area via a pressure- proof glass feed through. The resulting surface temperature is equivalent to the dew point. It is displayed or output via the 20mA stream loop.
