Description
The 31590TC Orbisphere Nitrogen (N₂) TC sensor is a selective thermal conductivity (TC) sensor engineered for continuous measurement of nitrogen in gaseous or liquid samples. Featuring a carbon dioxide purge connection, protection cap and an adapter for external temperature sensing, this sensor enables accurate, direct analysis without sample preparation. The rugged construction and compact design support operation up to 20 bar, with easy insertion into process lines or compatible flow chambers. Sensor cable and controller are ordered separately.
Advantages of 31590TC
- Selective nitrogen measurement with thermal conductivity technology — 31590TC.
- Carbon dioxide purge connection for reduced cross interference.
- External temperature sensor adapter for accurate temperature compensation.
- Rugged IP65 rated construction suitable for high pressure up to 20 bar.
- Compact form factor for easy integration into process line or flow chamber.
- Usage and Handling
Install the 31590TC sensor in a suitable flow chamber or inline process connection with proper fittings. Order and connect an appropriate sensor cable (e.g., 32505.03) and compatible Orbisphere controller. Ensure correct purge gas supply and calibrate according to controller instructions. Periodically verify measurement accuracy as part of routine maintenance. Sensors should be stored in original packaging and protected from contaminants before installation.
