Moisture Monitor Series 35 adopts mature aluminum oxide thin-film sensing principle together with optimized digital processing circuit. The measurable dew/frost point range covers −110 °C ~ +60 °C, supporting dual display modes of dew point temperature and ppmv moisture concentration, which can capture trace moisture changes down to ppb level in various process gases. The built-in automatic temperature compensation and probe curve calibration function effectively offset measurement deviation caused by working condition fluctuation, and the optional response acceleration software shortens the system response speed during rapid drying process to 3–5 minutes, improving timeliness of process adjustmentpruemmfeuc....

This monitor supports diversified installation forms including rack-mounted, desktop, panel-mounted and NEMA4X waterproof field type, adapting to indoor central control rooms and outdoor harsh pipe gallery environments. Equipped with a 16-character backlit LCD screen and front membrane keypad, staff can complete parameter setting, calibration configuration and data viewing locally. It reserves an isolated 4–20mA analog output interface for data upload to DCS and recording instruments, equipped with one fixed fault alarm relay and two configurable upper/lower limit alarm relays to trigger interlock protection when moisture exceeds the threshold; sealed relay options are available for hazardous area deployment requirements.

All calibration data of the instrument is traceable to NIST standards, and each unit passes aging screening and precision detection before delivery to guarantee long-term measurement stability. The matched M-series probe is equipped with sintered stainless steel protective cover to block pipeline impurities and extend service life. The whole machine runs with low power consumption and supports long-term 24-hour unattended operation under 95% non-condensing humidity within normal working temperature rangepruemmfeuc....

Long-term operation will cause probe surface contamination and calibration drift, leading to inaccurate moisture data and risks such as pneumatic instrument failure and pipeline internal corrosion. Replacing calibrated original equipment and matching probes can quickly restore measurement accuracy and reduce instrument maintenance downtime. New MMS35 units are configured for gas drying system construction and transformation projects, while spare monitors are used for daily maintenance replacement of online moisture monitoring equipment. Accurate moisture data helps enterprises reduce energy consumption of dryer equipment, lower pipeline corrosion maintenance costs, and provide stable data support for safe and standardized operation of industrial gas supply systems under long-cycle continuous production conditions.
