HK Microwave Consistency Transmitter

StockRite™ Family of Mechanical and Microwave Consistency Sensors

The TECO HK Series of microwave consistency transmitters provide a versatile, safe and easy-to-calibrate means for measuring the consistency of paper stock. The HK Series can successfully measure broke, recycle or other difficult fiber types, independent of fiber length, freeness or wood species.
Typically less than half of the cost of other microwave transmitters, the HK series microwave transmitters will measure the percentage of total solids of additives in water and percentage of moisture in wood chips with the same transmitter. Applications include measurement and control of machine, recycle & broke stock, measurement and control of % totals solids of starch additives, measurement and control of % solids (limestone, kaolin clay) in coatings.
  • Low cost – typically less than half the cost of other microwave transmitters
  • Easy to install
  • One point calibration
  • Adjustable antenna units to maximize sensitivity to process conditions
  • Internally compensated for temperature
  • No routine maintenance required. Install & forget!
  • Current and Digital Outputs
  • Contact closure
  • Versatile – Same transmitter can be used in Pipes, tanks, chests, belts & chutes.
