Moisture Measuring Sensors
FS1 - The classic

FS1 - The classic

Disc design, fix mounting flange with 3 screw holes, abrasion cover freely selectable

Product description

FS1- The disc-sensor in the traditional housing but with newest high tech measuring electronics. Many customers like the traditional housing... So we also offer this housing in use with 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 wear protections:
• Special-Ceramic (extremely abrasion resistant)
• Wear resistant rubber (abrasion resistant, impact proof)
• Teflon (normally used in food industry or for sticky materials)

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

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

Technical data

+0.5 °C to +80°C (Temperature range G80, optional)
Probe type FSH: +0.5°C to +190 °C at the measuring surface only,
permissible environmental temperature max 80 °C

Storage: -25 °C to +65 °C
Connecting to the probe 4 meter screw-/ plugable connecting cable: 5 x 0,22m² shielded
Cable is assembled with metallic terminal sleeves.
Conformity Conforms to the CE-directive EMV 89/336EWG
Operating temperature +0.5 °C to +50 °C standard
