This is a Series SPTM-6V position transmitter, a flameproof smart-type unit for rotary motion sensing, certified Explosion Proof Ex d IIC T6, and fitted with a NAMUR-type lever for mechanical coupling to a valve or actuator shaft. Ex d IIC T6 certification means the enclosure is designed to contain any internal spark or explosion so it cannot ignite a surrounding hazardous atmosphere, and the NAMUR lever is a standardised mechanical interface for mounting to quarter-turn valve actuators.

The "smart" designation on this series typically indicates a transmitter with a configurable/microprocessor-based output rather than a simple mechanical switch, but exact output signal type (4-20mA, HART, or similar) is not confirmed in our record and should be checked before specifying it into a control loop.
