FAQ
It sits on top of the actuator and signals when the valve is fully open or fully closed, so the control system knows the valve position. A dome indicator also shows the position on site.
Choose the ITS 400: explosion proof Ex d IIC T6 for Zone 1 and 2, built to EN 50014 and 50018. For corrosive sites the ITS 500 has the same rating in a 316L or Duplex stainless housing. Tell us the zone and gas group and we’ll confirm the build.
Two mechanical SPDT switches are standard. Options include DPDT switches, P&F or Autonics proximity sensors, magnetic sensors, and a position transmitter with a 0–1 kΩ or 4–20 mA output.
Yes. The ITS series is IP67 as standard, with IP68 as an option on the ITS 400 and 500. For offshore and corrosive service, the ITS 500 has a 316L or Duplex stainless housing.
Mounting brackets follow VDI/VDE 3845 (NAMUR): SSIN1 and SSIN2 come with the switch box, SSIN3 and SSIN4 are optional. Send us the actuator make and size and we’ll supply the right bracket.
Tell us the actuator make and size, the area classification and the switch type you need, and we’ll match the box and bracket and quote it.
