Presentation

Pt100 compact thermometer, with optional integrated IO-Link and 4–20 mA transmitter, programmable PC

The compact thermometer measures the process temperature using a Pt100 sensor element (Class A, 4-wire). An optional integrated transmitter converts the Pt100 input signal. In the version with integrated electronics, the device automatically detects the connection variant (IO-Link or 4–20 mA).

Fast installation and easy commissioning :

- Small, compact design made entirely from stainless steel
- M12 connection with IP69 for easy electrical connection
- Pt100, 4-wire connection or universal output (IO-Link / 4–20 mA)
- Preset measuring range

Excellent metrological properties thanks to innovative sensor technology :

- Extremely short response times
- High level of measuring accuracy even with short immersion lengths
- Improved measuring accuracy with transmitter-sensor matching

Reliable operation ensured by approvals and certificates :

- Device safety to EN610101-1 and CSA C/US
- Electromagnetic compatibility to NAMUR NE21
- Diagnostics information to NAMUR NE43
- Hygiene-compliant design with 3-A marking
- Marine approval
