Turck expands line of valve position sensors

Automation manufacturer Turck has released two extensions to its line of inductive angle sensors for rotary actuators for harsh environments.

One of the new RI360-DSU sensing solutions includes a stainless steel Minifast connector and the other, using a terminal chamber, comes with ATEX and IECEx approvals. 

The sensors utilise the inductive resonant circuit measuring principle and introduce an open face sensor design for rotary valve sensing.

The RI360-DSU open faced inductive angle sensors deliver analogue or discrete outputs and provide flexible mounting options previously not available.

The sensors are able to monitor quarter turn valves and three-way valves, while also detecting the valve position during cleaning cycles.

Additionally, they are capable of detecting the wear of seals, thus saving downtime from seals that are worn from switching cycles.

For flexible operation, the sensors are available with switching or analogue outputs. 

“These products will not only allow for continuous 360° contactless position measurement, but now we have an Ex approved solution with the ability to be located within hazardous environments and a stainless steel connector option for use with harsh chemicals,” said Marty Cwach, product manager, Turck.

Featuring a protection rating of IP67 and a rugged, compact housing design, the RI360-DSU sensors provide a wear-free sensing solution in harsh applications.

The sensors provide optimal performance in temperatures ranging from -25°C to 75°C (EXI version limited to 70°C), making them suitable for a wide range of applications, including valve automation, steering position feedback, and dancer arm control.

The RI360P1-DSU35TC-ELI-EXI is available with ATEX and IECEx approvals while the RI360P1-DSU35-ELIU5X2-B1150/S1265 is available with a stainless steel Minifast connector.
