  • 2. TECO Stockrite™ Family of Consistency Transmitters TMC6000 Transmitter The TMC-6000 Microprocessor Consistency Transmitter is designed as the backbone for the TECO StockriteTM family of consistency instrumentation; to be used as the common electronics support platform for all of TECO’s family of consistency probes. The TMC-6000 is a remote mounted unit, making it an excellent choice for high vibration, high temperature, or inaccessible applications. Its microprocessor based electronics allow the user to have a set of predefined calibrations for easy set- up and calibration. Users can also retain up to (10) ten different calibration parameters to accommodate different grades or stock furnish mixes. The TMC-6000 also allows for “active velocity compensation” which significantly increases overall application range and maintains accuracy as your production rate changes, unlike standard mechanical devices.Sensor SpecificationsSensor Materials Temperature Cable Consistency Velocity Sensor Other Range Length Range % Range fpsC3000 Titanium 316SS 250ºF 20’ 2.5%-18% 0.1-6.0C5000 Titanium 316SS 250ºF 20’ 2.5%-18% 0.1-6.0C9700 Titanium 316SS 250ºF 20’ 1.5%-12% 1.5-10.0HK 316SS 316SS 338ºF 3’ 0.5% and up N/ANotesPartial list of specifications only.

  • 4. DrainacTM IIIB Online Freeness Transmitter Description The DrainacTM operates on the basic principle of how easily water will drain through a pad of fiber. Approximately every 30 seconds, the DrainacTM measures the rate of filtrate flow though a fiber pad. The DrainacTM consists of a totally enclosed vertical riser which has no moving parts. The compact detector is mounted directly in a pressurized stock line, or open vessel, avoiding any sampling lags or transport delay time. For pressurized applications, stock rises into the detector tube under controlled differential pressure. Fibers are retained on a perforated plate and filtrate passes through the pad which is formed. The time required to draw a known volume of filtrate through the pad is used to calculate freeness. For non-pressurized applications, the DrainacTM employs negative pressure to draw the stock sample into the detector tube for drainage rate determination. Once the freeness has been determined, air pressure is increased to return the filtrate and fiber to the stock line in preparation for the next cycle. At the same time, flush water is introduced into the chamber to clean the screen and the interior of the chamber. Cycle time ranges from 30-60 seconds.
