Lightning protection for transducers
Feb 03, 2009
Lightning protection for transducersThe manufacturer of KPSI Level and Pressure Transducers now offers lightning protection for its Series 300 small bore submersible level transducers for increased reliability. The Series 300 features protection against fast rising voltage transients with the use of two surge protection components, one located in the 0.75 inch OD 316 housing of the transducer and one located at the surface, grounded via DIN-rail or ground wire. The Series 300 is designed for small-bore applications to meet the rigorous environments encountered in a variety of water level measurements. With an option of welded 316 SS or titanium construction, this transducer family features a rugged, waterproof design and is ideal for ground water and surface water monitoring, down hole, dewatering, level control, and shipboard-use applications. Featuring a highly accurate pressure sensor assembly and optional chemical-resistant ETFE cable jacket, the Series 300 can stand up to the harshest environments that contain hostile fluids and gases. This transducer series offers custom level ranges up to 700 ft (210 m) H2O and an accuracy of up to „b0.05% FS. The Series 300 also features an analog output of 4-20 mA, 0-5 VDC or mV. Each transducer includes the latest Pressure Systems¡¦ SuperDry Long Life Vent Filter that prevents moisture from entering the vent tube for at least one year without maintenance. An optional aneroid bellows instead of a vent filter can be supplied with the Series 300 for applications where periodic maintenance is not practical and extremely high accuracy is not required.
