Krohne Optitemp TRA-C10, TRA-C20 and TRA-C30 temperature sensors

The Optitemp TRA-C10, TRA-C20 and TRA-C30 line of compact temperature sensors can be preconfigured with an integrated transmitter to meet the most common requirements for measuring range and immersion length, as well as process and electrical connections.

Although they are for different fields of application, the TRA-C10, TRA-C20 and TRA-C30 share the same basic design: equipped with Pt100 class A sensor element and build-in analog transmitter, they cover the temperature range from -50 to +150°C (+200°C without an integrated trasnmitter) for liquid and gaseous media. Accuracy is ±0.15% of measuring range. For immediate use, the measuring range is fixed and preconfigured to a 4-20 mA output with no programming required.

All three sensors come in standard immersion lengths 50 or 100 mm (or, on request, 25-500 mm). Classed IP67/65, the sensors are dust tight and can be used in wet outdoor environments. The solid mechanical design has no moving parts, making them highly resistant to mechanical stress.

The TRA-C10 is a hygienic compact temperature sensor suitable for OEM applications in the food and beverage, pharmaceutical or sanitary industries. It comes with process connection ISO 2852 DN25/38, and the electrical connection is a standard M12 connection. The TRA-C10 can be CIP cleaned.

The TRA-C20 is a compact temperature sensor for general process applications. It comes with G1/2 process connection and standard electrical connection valve EN 175301-803.

The TRA-C30 is a compat temperature sensor with process connection G½″ as standard and M12 electrical connection.
