Product Overview
Continuous Moisture Measurement Without Sampling Delay The MS-204 is an insertion-type microwave moisture analyzer for continuous measurement directly inside industrial process materials. Installed in pipelines, tanks, vessels or material-handling equipment, the probe provides real-time moisture data and helps reduce dependence on periodic manual sampling. Final configuration depends on the material characteristics, process conditions and equipment structure.
Suitable Process Media
Suitable for selected: Solids, powders and granules Process liquids Industrial slurries Final suitability depends on material characteristics, moisture range, temperature, pressure and installation conditions.
Measurement Principle
The MS-204 transmits microwave signals into the measured material. Changes in moisture affect microwave energy attenuation and electromagnetic response. An application-specific calibration model converts the measured response into continuous moisture values.

Key Advantages

1、 Direct In-Process Measurement

The insertion-type probe measures moisture directly inside pipelines, tanks, vessels and process equipment, reducing dependence on manual sampling.

2、 Fast Process Feedback

An output response time of 500 ms supports continuous moisture monitoring, earlier detection of moisture variation and timely process adjustment.

3、 Industrial Probe Design

The probe features an SS304 housing and special PE measurement surface for direct contact with selected industrial process materials.

4、 Flexible Installation and Integration

Supports threaded or flange mounting, 4–20 mA output and RS485 communication for integration with PLC and DCS systems.
