Encoders and sensors used in the oil and gas industry must withstand high temperature and pressure, 
potentially explosive locations, and extreme shock and vibration, along with exposure to chemicals, dirt and 
moisture. Position sensors perform crucial functions in oil and gas applications and must operate reliably day 
in and day out to ensure an optimized yield. CARLEN Sensors is well aware of these unique upstream, 
midstream, and downstream requirements and has designed products that feature uncompromising quality 
and performance for these hazardous environments. Hard-anodized housings, gross leak tests, extended 
temperature ranges and a variety of sealing options are available on numerous CARLEN products.
