    0.01-3.5%. Based on BTG's patented Peak Method (see section 1.3) of optical anal- ysis, the TCT-2301 is virtually insensitive to variations in filler and fines content, making it particularly suitable for use with recycled and me- chanical pulp suspensions.

  • Page 8: Technical Data

    The TCT-2301 is served by the SPC-1000 hand-held terminal, which works not only with the TCT-2301, but also with all instruments in the BTG family of smart transmitters. The SPC-1000 can be connected at any point on the 4-20 mA output signal loop.

    8 Input signals 9 Output signals PEAK The TCT-2301 employs the patented peak method for measuring total consistency of pulp suspensions. This technology is based on the fact that suspensions contain both large and small particles. Large particles are typically fibers and small particles are fillers and fines.
