Thermistor Temperature Transmitter
“Smart” in-head transmitter

• Supports Many Thermistor Types
• 2-Wire, Loop Powered
• 4 to 20 mA Output
• PC Configurable Ranges (requires programmer)
• High Stability

Description

The TX206TH is a cost effective “smart” in head transmitter that accepts thermistor temperature sensors and converts sensor output over a configured range to a standard industrial (4 to 20) mA transmission signal.

A variety of thermistor types are available when using the configuration software: select thermistor type, temperature range, units and burnout direction, without requiring calibration equipment. PC configuration is performed quickly using our new USB port driven configurator by simply connecting two clips to the TX206TH loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use.

Alternatively, a single push button and LED indicator allows the user to configure transmitter range against a manually set input condition. A red LED is included to help guide the user. The LED also operates as a sensor error indicator.

Transmitters can be factory configured for any range specified at the time of order, removing the need for user configuration.
