Overview: The OPTITEMP TT 12 series includes transmitters designed for use with Pt100/Pt1000 sensors and thermocouples. The series is divided into two main types: OPTITEMP TT 12 TC for thermocouples and OPTITEMP TT 12 RTD for resistance temperature detectors (RTDs). These transmitters are known for their reliability and performance, with minimal impact from external factors such as temperature, vibration, moisture, and electromagnetic interference.

Key Features:

• Wireless Configuration: The transmitters can be configured wirelessly via NFC using a smartphone or tablet, eliminating the need for expensive tools or fixed workstations.
• Compact Design: The head-mounted variant is 10.5 mm high, and the rail-mounted variant is 6.3 mm wide, allowing for easy installation and space-saving in cabinets.
• High Quality: Built on KROHNE’s latest transmitter platform, ensuring high quality and efficiency.
• Configuration Control: The OPTICHECK Temperature Mobile app allows users to save, share, and document configurations easily.

Technical Specifications:

• Input Types: Supports Pt100, Pt1000, and various thermocouple types (B, E, J, K, N, R, S, T).
• Output: 4-20 mA, temperature linear, non-galvanic separated.
• Measuring Range: -200 to +850 °C (-328 to +1562 °F) for RTD; specific ranges for different thermocouple types.
• Accuracy: Maximum of ±0.15 K or ±0.15% of span for RTD; varies for thermocouples.
• Power Supply: 6 to 32 VDC.
• Environmental Conditions: Operates in temperatures from -40 to +85 °C (-40 to +185 °F) and humidity up to 98% RH (non-condensing).
• Vibration and EMC Compliance: Meets IEC 60068-2-6 and EN 61326 standards.
• Long-term Stability: Maximum drift of ±0.05% of span per year.

Additional Information: The OPTICHECK Temperature Mobile app is available for free download on the App Store and Google Play Store, providing easy access to configuration tools and documentation.
