Product Specification

TCSMA - Loop-Powered, Isolated Toroidal Conductivity Transmitter

TCSMA Toroidal Conductivity Transmitter Features
• 4-20mA isolated output, loop-powered (16-35V DC)

• User-adjustable temperature compensation (0-4%/ deg C)
• Selectable measuring ranges
• Adjustable zero and span
• Direct/reverse operation
• Nema 4X enclosure with multiple mounting configurations

TCSMA Toroidal Conductivity Transmitter Description
The TCSMA model is designed for on-line monitoring of water treatment applications and aggressive process chemicals. This blind transmitter is ideally suited for applications where 4-20mA signals are required and reliable instrumentation is critical.

Key features include: selectable measuring ranges, adjustable temperature compensation (%/deg C), isolated output and reversible cell drive.

A Nema 4X (IP66) enclosure provides durability. A variety of mounting choices are available for Wall, Pipe or DIN Rail installation.

Pair the TCSMA with a TCS3020 toroidal sensor for trouble-free service. TCS3000 and TCS3020 sensors are offered in Noryl construction and can be mounted in a custom flow cell (FC95C) for in-line use.
