Measures dew point from -60 to 80 degC with an accuracy of ±2degC
Vaisala DRYCAP® sensor provides accurate, reliable measurement with excellent long-term stability and fast response
Display numeric and graphic data — up to one year of measurements trends
Two analog outputs and a serial interface
The Vaisala DMT-series transmitters are designed for demanding industrial applications with dry conditions. Typical applications include compressed air drying and metal treatment. It offers reliable, accurate measurements with excellent long-term stability in dew points down to -60 degC (-58 degF). The DRYCAP® sensor is immune to particulate contamination, water condensation, oil vapor and most chemicals. Since the sensor withstands condensation it offers unmatched performance in low dew point applications that experience water spikes in the process. Model 37804-53 features a graphic/numeric display and an easy-to-use, menu-based user interface. Both models having datalogging capability. One year of dew point and temperature data is automatically stored in the microprocessor and can be viewed locally on the display (37804-53), or downloaded to a PC to study historical trends. The unique auto-calibration function, patented by Vaisala, is a calibration and adjustment that the transmitter performs by itself while the measuring process is running. If the measurement accuracy is not confirmed, corrections are made automatically to the calibration curve.
