About Vaisala Dewpoint Transmitter (Vaisala) DRYCAP? DMT143 Dewpoint Transmitter is a compact sensor dew point measurement instruments, which can be installed directly at the maximum 50 bar (725 psia) pressure system. Vaisala (Vaisala) DRYCAP? Sensor technology has long-term high-performance operational performance. The sensor is fully withstand humid environments, so DMT143 transmitter in the water splashing industrial applications can have very good performance, these applications include car during the process stages of system failure or pipe condensation. Sensors also extremely tolerant particulate impurities, oil and most chemicals, not sensitive to changes in flow velocity. Calibration cycle longer DMT143 calibration period up to two years time. Besides using the Vaisala (Vaisala) of DM70 hand-held dewpoint meter can to DMT143 online than to confirm its performance, without having to disassemble it from the system. If you need to adjust, take it to Vaisala Service Center. Process during normal operation, automatic calibration software also work online. When measuring accuracy can not be guaranteed, corrective work automatically. Easy to install DMT143 Dewpoint Transmitter has many features to choose from, including different output, mounting options and alarm LED lights. Due to small size, light weight, DMT143 in narrow space or a small size pipe is very easy and fast to install. LED lights for ultra-high dew point alarm, factories can be pre-set trigger point, with Vaisala DM70 hand-held meter table or a PC can also be re-set.
