Seeds and grain moisture sensor PCE-MWM 230

dielectric

When it goes about liquids and bulk materials the right choice is the dielectric moisture meter PCE-MWM 230. Generally speaking there are a few models of the moisture meter which are meant for measuring of some particular materials and that is why that device a very wide application (mining and petrochemical industry, production of building materials, agriculture). There is no need in calibration in advance, as the principle of the device is based on the direct method of permittivity measurement. The measurements can be carried out not only for homogeneous materials but also for materials with fractions (crushed stone, gravel, ore etc). The device is non-nuclear, which is a big advantage. Technical specifications: Measurement range: 0 ... 100 % Limits of permissible absolute error of the measurements results of the mass fraction of water: Δ= 0.02 +0,025·W Range of working temperatures 0 ... +90 °C (industrial version) 0 ... +115 °C (extended temperature range) 0 ... +250 °C (drying kilns) Operation mode: continuous operation Measurement period: 0.3 ... 1.5 s Voltage supply - Rated / - Allowable: 24 (18 ... 36) VDC Consumption current, not more than: 200 mA Input power: <0.1 W Warm-up time at start-up: 30 min Output: RS 485 Modbus RTU, 4-20 mA [RS485: max. cable length 1,000 m; 4-20 mA: max. cable length 100 m (max. cable length to SPS unit Input: digital 24 VDC Dimension of the sensor, length: L 200 ... 1000 mm, Ø 15 ... 30 mm (depending on the variant) Protection class: IP54 mass: 5 kg
