TMT85-A1A2A+B3 | Endress+Hauser TMT85 temperature transmitter 

The iTEMP TMT85 is a configurable head-mounted temperature transmitter with two universal input channels, converting signals from RTDs (Pt100, etc.), thermocouples, resistance (Ω) and millivolt sensors into standardized FOUNDATION Fieldbus H1​ digital output. The TMT85-A1A2C+B3 configuration is built for critical process applications where signal reliability, long-term stability and advanced diagnostics matter more than price.
