Eclipse™
StoneL Eclipse features dual solid state sensors with optional communications neatly integrated into a sealed module. The Eclipse series is available in non-incendive and intrinsically safe versions (EN) for hazardous areas with a removable module and in a general purpose completely sealed micro-connector version (EG).

Quartz™
The Stonel Quartz is available in explosionproof (QX), nonincendive and intrinsically safe (QN), low temperature (QC) and general purpose (QG) versions. The robust epoxy coated anodized aluminum construction makes this platform extremely durable and well suited for use in corrosive, heavy wash down environments.

Visual indicator
Clearly view valve position status from up to 75 feet with StoneL stand alone visual Indicator. The indicator’s rugged Lexan® construction makes the indicator resistant to physical damage and tolerant to most corrosives.

Prism™ PI
The Stonel Prism PI integrates an advanced position sensing system and integral pneumatic control for sanitary diaphragm and other linear applications. Compact and durable, the PI is suited for corrosive, heavy washdown and hazardous areas.

Hawkeye™ HX
The explosionproof Stonel Hawkeye, with its stainless steel enclosure, is designed for service in harsh process environments. It features a solid state proximity sensor which is encased in a shock absorbent urethane potting material. Outputs for universal switching or NAMUR (EN 60947-5-6; I.S.) are standard options.

Hawkeye™ HK
The solid state Stonel Hawkeye sensor is ideal for point sensing in corrosive and hazardous process environments. The standard Red/Green LEDs also speed your setup and installation by confirming power up and switch status. The Hawkeye is FM and CSA approved for nonincendive applications and intrinsically safe circuits in hazardous areas
