They can also sense minute pressure fluctuations, while subjected to very high static pressures. Series 102A4X ground isolated & 121A4X case isolated Hazardous Area Approved, dynamic ICP® pressure sensors satisfy such measurement requirements in monitoring, diagnostic, troubleshooting, and control applications typical of hazardous factory environments. Applications include monitoring dynamic pressure events, such as surges; pulsations; spikes; leak detection; combustion instability; and acoustics found in operation of compressors, pumps, pipelines and gas turbines. Sensors may be used with ICP® signal conditioning and permit use of a variety of inexpensive 2-wire cable systems. The lowimpedance signal may be transmitted over long cable distances, and sensors may be used in dirty environments without signal degradation. Series 102A4X ground isolation eliminates electrical noise from the structure under test; however, there is still a chance to pick up unwanted electrical noise from the environment. PCB® Series 121A4X case isolation eliminates all electrical noise from both environment and structure. As with all PCB® instrumentation, this equipment is complemented with toll-free applications assistance, 24-hour customer service, and is backed by a no-risk policy that guarantees satisfaction or your money refunded.
