图尔克的Ri-DSU35是第一款可以用于爆炸危险区域的非接触电感式角度传感器，非常适合用于阀门控制

Turck's Ri-DSU35 is the first contactless inductive angle sensor that also has ATEX and IEC-Ex approval for use in zones 1 and 21. Compared to dual sensors, the Ri-DSU35 offers considerable benefits for the position measurement of valves and stop valves in Ex areas: As it can detect valve positions in the full 360° range, it is also possible to monitor three-way valves. This enable the cleaning setting to also be detected and positioned exactly. As the sensor comes in the same housing as the conventional dual sensor, it can be fitted as usual with the extensive range of Turck accessories.

图尔克的Ri-DSU35是第一款通过ATEX和IEC-Ex认证，可用于1区和21区危险场合的非接触电感式角度传感器。相比于双传感器式阀位回讯，Ri-DSU35在检测爆炸危险区域中阀门和截止阀的位置方面具有显著优势：它可以在整个360°范围内检测阀门位置，因此也能够监测三通阀。这使得阀位可以被准确检测和定位。由于该传感器采用与传统双传感器相同的外壳，它可以像往常一样使用图尔克各类安装附件。

The contactless measuring principle of the Ri-DSU35 operates absolutely wear-free, thus ensuring a long service life and constant precision. Through the 360° detection of the valve position, the sensor also enables predictive maintenance. The user can thus detect a worn seal as soon as the sensor outputs a value that deviates from the originally expected flap end position.

Ri-DSU35的非接触式测量原理是完全无磨损的，因而确保了长使用寿命和稳定的精度。通过阀门位置的360°检测，该传感器还可实现预测性维护。一旦传感器输出偏离最初预期阀瓣末端位置值时，用户就可以立即检测到磨损密封件。

The Ri-DSU35 is provided with a terminal chamber connection. The terminal strip can easily be removed to maintain the drive and then refitted afterwards. This reduces personnel requirements for servicing since the terminal strip acts like a connector and can be plugged error-free without any special electrical knowledge.

Ri-DSU35配有接线盒。接线端子可以方便地拆除以便维护驱动器，并在随后重新安装。由于接线端子起到了连接器的作用，并且无需专业电气知识即可无错误地插入，因此降低了对维护人员的要求。
