FSV - The Universal
Adjustable flange probe for universal applications. Wide range of adjustment possible. Also suitable for thick wall situations. Can be mounted on a glider for measuring the moisture of materials on conveyer belts.
Product description
Our moisture measuring sensors always represent the latest technology of our well-proven high frequency measuring method and offer unique precision and reliability. Since decades we are in touch with our customers to be able to always give him an innovative product perfectly fitting his needs.
Sensors of the newest generation are available by different replaceable wear protections:
- Synthetic (Standard) For standard applications. Not suitable for abrasive materials. Good sliding characteristics.
- Ceramic (replaceable)
Extremely hard. Possesses a very high resistance against abrasion.
Cracks may form due to hitting stones or metallic objects. - Special rubber (replaceable)
Wear resistant rubber with good protective properties against
abrasions. No risk of cracks. - Teflon (replaceable)
Normally used in food processing technology and for sticky materials.
Accuracy: 0.1% . . . 0.5% depending on installation situation and correct calibration
Easy calibration of the sensor by integrated adjustment unit.
Output Signal: 0-10 V or 0/4-20mA - no additional processing unit required
Operating voltage: 9-30V DC (also available +15V DC and -15V DC)
Specific appointment of moisture thanks internal digital linearization of the measuring signal
Samples of application area:
• Moisture content of sand, gravels, etc in concrete production
• Reprocessing of foundry sand for desired moisture content
• Moisture content of quartz sand e.g. for glass manufacture
• Quality optimizing in food processing
• Corn production
• Fodder industry for animal food
• Ceramic powders and pastes; metal oxides
• Sludge from the sewage plants
• Soil humidity, etc
• Biosolids/ Sludge drying
Technical data
Connection to the probe |
Connecting cable: 5 x 0.22 mm2 shielded Cable is assembled with metallic terminal sleeves. Plug is optional. |
Signal output |
Standard: 0-10 V Output load resistance: 100 kohm Option: 0-20 mA or 4-20 mA Load resistance: 500 Ohm 0.1%, TK = 25 ppm |
Protection against damage by lightning | Sometimes, especially in open air installations, the probe can be damaged by lightning. In addition to reducing the risk by observing the guide lines laid down in the standard, VDE 185, Parts 1 and 2, it is necessary to equalize the potential between the probe and the processing electronic unit. This is achieved by earthing the cable shielding at both ends. |
Measurement range & internal calibration |
0% and % adjusting trimmer for calibrating the probe (optional) These allow one to adjust the measuring window of the probe to the desired range of moisture measurements for the material. Accessible only through a water tight screw on the probe cover. |
Protection level for the probes | IP68 |
Maximum Signal Values |
Voltage output: -0,7 V to app. 13V (RL = 100 k Ohm) Current output 0-20 mA: -1,4 mA to app.. 24 mA (Load = 500 Ohm) Current output 4-20 mA: +4 mA to app. 24mA (Load = 500 Ohm) |
Abrasion Protection of Sensor |
Standard: Surface material is synthetic Ceramic: 3 mm thick, extremely good resistance to abrasion but brittle Special rubber: extremley abrasion-resistant,impassible for bump/ shocks Teflon: for sticky materials and for use in the food industry |
Environmental conditions |
Operational: +0.5°C to +50°C (Temperature range G50, Standard) +0.5°C to +80°C (Temperature range G80, optional) permissible environmental temperature max 80 °C Storage: -25°C to +65°C |
Depth of insertion of the sensor edge |
