Control and Feedback Systems Control Top SES

The control top SES is used for potentially explosive areas.The SES is characterized by proven sensor technology. The control module consists of an interface top, up to 2 sensors for valve position feedback and up to 3 solenoid valves which can also be installed subsequently.

  •  For open/close position feedback and actuator control
  •  Intrinsically safe sensors and solenoid valves

The SES is only available in PA 12/L material, because conductivity of the material is required for use in ATEX/Ex areas.

Features

  • Proven Namur sensors
  • Quick and easy adjustment of the sensors
  • Flexible modular system
  • Selection of solenoid valves
  • Can be subsequently upgraded / converted

Position recording
Proximity switches – the valve positions are recorded using two manually adjustable proximity switches for the non-actuated and actuated position.

Setting
Mechanical – the sensors are calibrated mechanically using the positioning spindles, which are subsequently secured to prevent adjustment.

Visualization
The position of the switch bar projecting from the control module makes it possible to detect what the position of the valve is.

 

Field of Application

Use in potentially explosive atmospheres is permitted:

With proximity switch up to zone 1 and 20
For connection to approved intrinsically safe equipment ATEX identification:
II 2G Ex ia IIC T6
II 1D Ex iaD 20 T97 °C

With solenoid valve up to zone 0 and 20
For connection to approved intrinsically safe equipment ATEX identification:
II 2G Ex ia IIC T6

With interface module
Not subject to Ex approval because it is a purely passive component
