[. . . ] www. vaisala. com HMT300TMK Turbine Mounting Kit for Power Turbine Intake Air Measurement cause errors in measurement. The patented warmed probe prevents condensation from forming on the sensor. Protective enclosure The HMT300TMK includes a white, painted aluminum enclosure with an installation kit for the probe. [. . . ] It is ideal for measuring in water vapor injection applications because the sensor has been optimized for high humidity environments by utilizing a patented, warmed probe. Water vapor is added to the intake of the turbine to increase the mass flow which in turn increases compression and electrical power output. HUMICAP® performance The HMT330 Series Transmitters are fitted with the latest generation of the HUMICAP®, the polymer sensor known for its accuracy, reliability and long-term stability. The sensor has a high tolerance for particulate abrasion and chemical contamination. Features/Benefits Designed for high humidity applications Measurement range: -40 . . . +100°C Patented, warmed probe Incorporates Vaisala HUMICAP® Sensor for excellent accuracy and long-term stability and resistance to dust and most chemicals Low maintenance need Outer cover provides protection from rain and direct sunlight NIST traceable (certificate included) Low maintenance Power turbines also require exact water vapor injection in the chamber to reduce pollutant emissions. Vaisala's warmed probe technology is ideal because of its reliability in the field. In fact, the only suggested scheduled maintenance is annual calibration. Patented, warmed probe prevents condensation The HMT300TMK with the HMT337 installed, provides fast and reliable dewpoint measurement especially under high humidity conditions where dew would normally form on the humidity sensor and thereby Vaisala HUMICAP® Humidity and Temperature Transmitter HMT337 The HMT337 is intended for demanding industrial humidity measurement applications with a risk of condensation. The stainless steel probe is mechanically durable and preferred for most industrial applications.
