The HygroPro moisture transmitter is an intrinsically safe, compact, loop-powered moisture transmitter designed specifically to meet the demands of rugged industrial applications. With certified intrinsically safe electronics packaged in an IP67/Type 4X housing.
The HygroPro features an integrated backlit display and six-button keypad to provide viewing of up to three parameters simultaneously and to allow easy navigation of the software for configuration of the display, analogue and digital (RS485) outputs, and other user functions and diagnostics. Via the RS485 interface, the HygroPro built-in multidrop capability allow multiple units to be connected on a single network.
Using an industry-proven aluminium oxide moisture sensor, the HygroPro features a built-in temperature thermistor and pressure transducer to provide real-time measurement for calculation of parameters such as ppmv in gases, ppmw in liquids, pounds per million standard cubic feet in natural gas or percent relative humidity. Three sensors mounted on a single probe mount provide installation flexibility when space is limited. In addition, the HygroPro display can be oriented in four different orientations to allow installation of the moisture sensor in the top, bottom or side of a process pipe or sample cell.
The HygroPro consists of a display/keypad housing, and a replacement transducer element (RTE), which contains the aluminium oxide moisture sensor, temperature thermistor, and pressure transducer and associated electronics. The RTE is field replaceable by simply removing a small mounting plate and disconnecting a cable. Also, since the calibration data for the moisture and pressure sensors are stored in a non-volatile EEPROM in the RTE, a user does not need to enter any calibration data manually when changing an RTE.
The HygroPro combines a technologically advanced aluminium oxide moisture sensor with state-of-the-art software and electronics for unequalled overall performance.
Superior sensitivity, speed of response, calibration stability, and wide dynamic range have made GE aluminium oxide moisture probes the standard of performance and value in industrial moisture measurement. They are suitable for laboratory and industrial moisture measurement applications in gases and non-aqueous liquids over a wide range of process conditions.
The rugged, compact HygroPro transmitter is designed specifically for installations where space is at a premium. It can be installed directly in the process stream or, if necessary, in a sample system. If required, GE can design and build a sample conditioning system to meet unique application demands.
