Model 6020 Dewpoint Hygrometer Single Channel Advanced On-Line Dewpoint Hygrometer Model 6020 is a single channel, panel mounted, online hygrometer designed to accurately measure trace moisture in process gases utilising a range of dedicated, ultra high capacitance, field mountable sensors. The system incorporates an automatic calibration (AutoCal) facility and encompasses measurement needs from -110°C to +20°C dewpoint. The sensor has been designed and conditioned for long term stability, and together with its high sensitivity, allows use of up to 1km cable length between sensor and instrument. Additionally, the sensor is ATEX certified for intrinsic safety so can be used in hazardous environments with a suitable Zener barrier in the safe area. Offering full field interchangeability, each Model 6020 unit is factory calibrated with sensor to better than ±2°C accuracy and is supplied with a certificate of calibration traceable to International Humidity Standards. There are three Hot Key front panel key functions to gain rapid access to set alarms trip points and choice of displayed engineering units. These functions can be locked to prevent unauthorised tampering. Users may choose to view the trace moisture levels in °C dewpoint, °F dewpoint, ppm(v), ppm(w), g/m³ or lb/MMSCF on the 5 digit, seven segment LED display. The factory calibrated, but fully configurable, analogue current output is automatically linearly correlated with all the selected engineering units. Model 6020 contains two independent, fully user programmable alarm contacts to provide all the versatility required for any application. A digital communication channel is provided via a RS485 serial connection for remote interrogation of measured values and status of alarms and instrument. Should the need arise to set up the instrument differently to the factory provided configuration then a highly flexible, user configurable setup menu is built in. The features within the setup menus are protected by user configurable passwords to limit access and protect against unauthorised changes. Works with a range of sensors covering an overall range from -110°C to +20°C dewpoint (-166°F to +68°F) Units selectable for °C and °F Td, ppm(v), ppm(w), g/m³ or lb/MMSCF System accuracy better than ±2°C dewpoint equivalent Calibrations traceable to International Humidity Standards AutoCal calibration adjustment to maintain accuracy between laboratory calibrations On board pressure dewpoint calculator, including data for Natural Gas Molecular mass pre-loaded for ppm(w) in common gases, other gases can be entered Two fully programmable alarms with 10A relay contacts and status LEDs An analogue current output linear and range configurable for selected units RS485 port for digital output of measured value Large, easy to read, 5-digit LED display Hot Key functions for rapid access to set alarms and units, can be locked to prevent tamper Ex certified sensors for Hazardous Area use (via Zener barrier in Safe Area) Sensor cab
