The Panametrics HygroPro II moisture transmitter is an intrinsically safe, compact, loop-powered display transmitter designed to meet the requirements of industrial and hydrocarbon processing applications. The HygroPro II can measure moisture in both gases and hydrocarbon liquids, providing a 4-20mA output along with HART digital communication capability, utilizing Panametrics' latest -FX aluminum oxide moisture sensor.

The backlit display with 6-button keypad allows viewing of up to three parameters simultaneously and enables easy navigation of the software for configuration of probe measurement, analog and digital (HART) output, and other functions and diagnostics. Built-in networking capability through the digital HART interface allows multiple units to be connected on a single network.

The HygroPro II utilizes an aluminum oxide moisture sensor, a built-in thermistor, and optional pressure transducer to provide real-time measurement of sample dew/frost point, temperature, and pressure. This allows calculation of other moisture content parameters such as ppmv in gases, liquids, and pounds per million standard cubic feet in natural gas or percent relative humidity. The glass-to-metal seal in the probe mount is certified to meet ANSL/UL 122701 single seal standards, ensuring reliable isolation and protection of probe electronics.

The HygroPro II consists of a display/keypad housing and a replaceable transducer element (RTE) containing the aluminum oxide moisture sensor, thermistor, and optional pressure transducer with associated electronics. The RTE is field replaceable by loosening mounting screws and disconnecting an internal cable.
