Limit switches offering
Eclipse™ modular on/off valve monitor
The Eclipse platform by StoneL provides solid state valve monitoring capabilities in a very compact design for process on/off automated valves. The Eclipse is available with Universal voltage switching, Namur or bus networking control models in Ex I version.
Quartz™ explosionproof on/off valve monitor
The Quartz discrete valve monitor is available in explosionproof (QX), nonincendive and intrinsically safe (QN), low temperature (QC) and general purpose (QG) versions. The robust epoxy coated aluminum enclosure is extremely durable and well suited for use in corrosive, heavy wash-down environments. A broad range of switches, position transmitters and communication options are available to accommodate most applications.
Hawkeye™ linear point sensors
The Hawkeye sensor platform by StoneL provides solid state valve monitoring capabilities in a very compact design for linear valves like gate & globe valves. The Hawkeye is available with universal voltage switching or Namur sensors.
FieldLink™ accessories and tools for process networks
The FieldLink product group enables users to take advantage of field-based communication technologies to cut installation and maintenance costs and improve operating performance. With communication networks, vital predictive maintenance and performance measures may also be transmitted from field instruments to the asset management or operation control centers further reducing maintenance costs.
Easyflow by Neles™ limit switches, K-series
The Easyflow by Neles K-series features versatile limit switches for quarter turn actuators and valve assemblies. With the K-series limit switches our customers receive reliable end limit information of desired rotary travel. Available in selected market areas.
