Dew point/moisture transmitter Manufacture in india. ATS-305DT Series are field transmitter designed for rugged industrial environment. They employ advanced digital technology to provide reliable and highly accurate measurement. The well proven high capacitance sensor offers exceptional resistance to contaminants like organic vapours. The aluminium oxide sensor transmitter has auto cal. feature while the thin film capacitance has one point calibration. Its linearised 4-20mA DC can interface directly with any receiving instrument. Special Features: 1. Micro Controller Based. 2. Can be calibrated for Dew Point, Moisture, 3. Vapour Pressure, Humidity. Available in both explosion proof or weather proof housing. 4. 4-20mA DC, output as standard. 5. RS 232 / 485 Modbus Output Optional. 6.
