Intrinsically safe valve open/closed sensor for ATEX areas

June 2015 Sensors & Transducers

ATEX approved equipment and devices need to be strong and durable to withstand the elements that they will be exposed to in hazardous working environments. To this end, ifm electronic has designed and developed its newest line in ATEX protection.

The type IND inductive sensors are intrinsically safe and consist of two inductive sensors in a potted and robust housing with IP67 protection rating. They are equipped with connection for solenoids and two sensors are built-in: one sensor provides a signal when the valve is open, the other when it is closed.

The solenoid connection is optionally a standardised M20 x 1 connector or an M12 connection. The terminal chamber is easy to open and close, and since the terminal block can be removed, no new wiring is required if the sensor is replaced. The units are approved to ATEX categories 1D/1G and 2G.

The IND sensors provide easy access to the terminal chamber and feature a removable terminal block for easy wiring and a robust and resistant housing. They have a permanently legible label, and fit directly onto valve actuators.
