Supported Applications

The Omega TX206TH is a loop-powered "Smart" in-head transmitter designed for thermistor input with a (4 to 20) mA output. The device is engineered for mounting inside a DIN standard termination head, providing IP65 protection when installed within a suitable enclosure.

Operating Conditions & Performance

The TX206TH operates across an ambient temperature range of -40 to 85 °C. It accepts thermistor inputs and provides a process output configured for ranges such as 0 to 100 °C, with the series supporting measurement capabilities from -205.0 to 1000.0 °C depending on configuration. The unit requires a supply of 30 V dc (reverse protected to -30 V dc) and operates within an input voltage range of ± 3.0 V.

Configuration Options

The series supports configurable settings via USB or manual range setting, utilizing the USBSpeedLink software and a USB Configurator Kit. Key configuration parameters include:

  • Sensor Input: YSI 10K B thermistor.
  • Output Signal: (4 to 20) mA two-wire loop powered output.
  • Error Output: Configurable error signal at 21.0 mA.

Mechanical installation features a diameter of 43.0 mm and height of 21.0 mm, with fixing centres at 33.0 mm and two 5.5 mm mounting holes. Electrical connections are made via screw terminals (5 terminals labeled 1-5), accommodating sensor wires that must be less than 3 metres to maintain CE compliance; screened or twisted pair cable is recommended.

Key Product Differences

The TX206TH series includes factory default configurations for specific process outputs, such as the 0 to 100 °C range. The device contains no user serviceable parts or internal adjustments and must be installed by competent qualified personnel with adequate protection from moisture and corrosive atmospheres.
