Krohne has introduced Optitemp TRA-C10, TRA-C20 and TRA-C30, its new line of compact temperature sensors that follow the current trend where traditional temperature sensors are replaced with compact ones, especially in OEM applications.
Unlike traditional sensors that have to be configured by choosing from various combinations of measuring insert, thermowell and transmitter, the compact sensors are pre-configured with an integrated transmitter to meet the most common requirements in terms of measuring range, immersion length as well as process and electrical connections. Their main advantage is their size: in many process and OEM applications there is only limited space for sensors and these feature a small housing design.
Although they are intended for different fields of application, Optitemp TRA-C10, TRA-C20 and TRA-C30 share the same basic design. Equipped with Pt100 class A sensor element and build-in analogue transmitter, they cover the temperature range from -50 to 150°C for liquid and gaseous mediums. Accuracy is ±0.15% of measuring range.
All three compact sensors come in standard immersion lengths and the short transmitter response time indicates changing process conditions quickly to allow immediate reaction. Classed IP67/65, the sensors are dust tight and can be used in wet outdoor environments. The solid mechanical design has no moving parts, which makes the sensors highly resistant to mechanical stress or adverse environmental conditions.
Optitemp TRA-C10 is a hygienic compact temperature sensor aimed at OEM applications in the food and beverage, pharmaceutical or sanitary industries. It comes with process connection ISO 2852 DN25/38, electrical connection is a standard M12 and the device is suitable for CIP.
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 for international markets.
TRA-C30 is a compact temperature sensor with process connection G1/2 as standard and M12 electrical connection.
Non-standard combinations are also available on request.
