Grain moisture meters

FIZEPR-SW100.11.41 sensor

In-line microwave moisture meters FIZEPR-SW100 are designed to measure moisture content in grain and grain products located in hoppers, dispensers or transported on a conveyor belt. High working temperature range of sensor operation (up to +180°С) makes it possible to built sensors directly in drying equipment.  

Controlled products: grain, flour, grits, seeds, feed stuff and other agricultural products.

Moisture analyzers are entered into the State Register of Measuring Equipment of the Russian Federation:   in Russia - Certificate RU.C.31.001A №56698,  in Kazakhstan - Certificate №12284. The general catalog (price list) moisture meters for bulk and paste-like materials is provided here: Price-list_2021

By the measurement principle, FIZEPR-SW100.1x moisture analyzers are classified as microwave dielectric moisture meters.  The feature of these analyzers is the direct method of permittivity measurement providing maximum possible moisture measurement accuracy. Moisture meter advantages include a large volume of the material controlled at a time, which eliminates any errors related to heterogeneous moisture distribution in the material. FIZEPR-SW100 moisture meters have no rivals in terms of specifications.

The moisture meter consists of an electronic unit and a sensor. The moisture meter contains a probe made as an AISI 321 stainless steel bar 10-30 mm in diameter. This solution determines an extraordinary strength and service life of the sensor, resistance to mechanical loads, shocks, abrasion.

Serial sensors of the moisture meter for grain products are supplied in several versions different in the probe type: 

1. The probe of the FIZEPR-SW100.10.6 (FIZEPR-SW100.10.21) sensor is configured as a flat-topped bracket which is mounted on the hopper wall via couplings.

2. The probe of the FIZEPR-SW100.10.4 (FIZEPR-SW100.10.41) sensor is made as a straight rod with ends secured on the opposite walls of the hopper through special couplings. The sensor controls large material volumes and provides accurate moisture content measurements at heterogeneous moisture distribution in agricultural products.

3. The FIZEPR-SW100.11.х sensor probe contains two parallel pins. The sensor can be secured on a 1" pipe installed inside a tank.

FIZEPR-SW100.10.4 and FIZEPR-SW100.10.41 moisture meters

Moisture meters of FIZEPR-SW100.10.6 and FIZEPR-SW100.11.41 versions are used both in hoppers and on conveyors.

FIZEPR-SW100.11.41 moisture meters are most suitable for measuring moisture content in grain products stored in hoppers. The sensor of this versatile moisture meter is installed by just welding a nozzle with a standard flange to the hopper wall (Version 1-40-6 GOST 12820-80). The depth of sensor immersion into a silo is determined by the length of the pipe used for sensor mounting with a G1" coupling. When ordering, all the required mounting fixtures may be included in the scope of FIZEPR-SW100.11.41 moisture meter supply.

Moisture meters of FIZEPR-SW100.10.6 and  FIZEPR-SW100.11.41 versions can be used in drying units.  Sensors for this application are made in a heat-resistant version with a working temperature of 180°С. 

FIZEPR-SW100.10.6

Suitable for any products: grain products, feed stuff, flour, sunflower seeds

FIZEPR-SW100.1х series moisture meters provide high measurement quality by averaging measurement results throughout the large volume of the controlled material.

Sensor has a sealed design and features high reliability and resistance to mechanical stresses.

Stainless steel ensures corrosion resistance and makes it possible to install moisture meters in grain dryers with temperatures up to 180°С.

Guaranteed service life of FIZEPR-SW100.1х moisture meters is 24 months.

Options for integration into automatic process control systems

FIZEPR-SW100 moisture meters are equipped with standard interfaces (4...20 mA, MODBUS RTU) and can be connected to automatic process control systems.  Moisture meters used in drying units make it possible to automate the grain product drying process and save energy.
