SensoGate WA 130-FOS

Universal, pneumatically operated retractable fitting with modular design

High Availability

The sensor lock-gate principle allows rinsing the O-rings during the stroke movement. Therefore, the integrated O-rings are notably less exposed to stress than in conventional fittings. Wear is reduced and durability is increased.

Safety

The point of separation between the stroke cylinder and the calibrating chamber is double sealed and ventilated. This prevents media from escaping from the calibrating chamber into the drive unit, and conversely prevents compressed air from entering the calibration chamber. SensoLock prevents the immersion in the process when the sensor has been removed.

Plug & Play Installation

The central multiplug contains tubings for rinsing, cleaning, and calibration media, including limit switches and check valves and enables a fast, safe, and space-saving connection.

Easy Maintenance

The particular ease of maintenance of the sensor lock-gate is achieved by a well thought-out design that allows performing virtually all maintenance on the site without the aid of a workshop. Drive and immersion tube can simply be taken off by loosening a coupling nut, without complete dismantling. The immersion tube is divided by a bayonet coupling to allow replacing only the particularly stressed process-wetted part including calibration chamber which helps to reduce costs.

Efficient Rinsing

Another unique feature is the tangential routing of the rinsing media with high flow rates for optimum cleaning effect.
