Sensors for critical applications

Accelerometers with External Electronics
	The CA series of sensors are high-temperature, piezoelectric-based accelerometers designed for the long-term measurement and monitoring of absolute vibration in the most severe of environments (up to 700°C). Key features: Available in standard versions and in Ex versions certified internationally for use in hazardous areas. Suitable for high-temperature environments (up to 700°C) and safety-related applications such as IEC 61508 SIL 2 or ISO 13849 PL cCat 1 certified measurement chains. Qualified by major OEMs for industrial vibration monitoring. Visit this product webpage here.
Accelerometers with Integrated Electronics
	The CE and SE series of sensors are piezoelectric-based accelerometers that come with either attached electronics for higher temperature applications (up to 350°C) or integrated electronics for lower temperature applications (up to 120°C) with excellent low-frequency response (down to 0.2 Hz) . These sensors are suitable for the vibration monitoring in steam turbines, smaller hydro units using rolling element bearings and/or speed-reducing gears that require monitoring using accelerometers, compressors, pumps, and fans. Key features: Available in standard versions and in Ex versions certified internationally for use in hazardous areas. Attached or integrated electronics so installation is easier (no external signal conditioners and simpler cabling). Visit this product webpage here.
Moving-Coil Velocity Sensors
	Our CV21x and VE210 moving-coil velocity sensors have the advantages of being self-powered and providing a strong output signal in native velocity units (mm/s), so the signal to-noise ratio is excellent, and no integration is required. Key features: Velocity sensors using the moving-coil principle provide a high signal-to-noise ratio in the low frequency range. CV sensors are Ex certified for use in hazardous areas.

Dynamic pressure sensors
	The CP series of dynamic pressure sensors are high-temperature, piezoelectric-based pressure sensors designed for the long-term measurement and monitoring of combustor pulsations and combustion dynamics in gas turbines. Key features: Available in Ex versions certified internationally for use in hazardous areas. Suitable for high-temperature environments (up to 700°C) and safety-related applications such as IEC 61508 SIL 2 or ISO 13849 PL cCat 1 certified measurement chains. Allows high-temperature lean-combustion monitoring – the key to reducing NOx and other emissions. Visit this product webpage here.
Proximity probes
	The TQ series covers a broad measurement range from 2 to 12 mm and are designed to withstand pressures up to 100 bar from speed and vibration to large-displacement expansion measurement using pendulum probes. Key features: Available in standard versions and in Ex versions certified internationally for use in hazardous areas. Broad family of sensors with different measurement ranges (sensitivities), mounting options (standard, reverse orright-angle), and pressure capabilities (up to100 bar). Suitable for safety-related applications such as IEC 61508 SIL 2 or ISO 13849 PL c Cat1 certified measurement chains. Conforms to API 670 5th edition. Visit this product webpage here.
Air-gap sensors
	The LS series of air gap sensors covers a broad measurement range from 5 to 60 mm (linear), features enhanced filtering of noise and spikes and provides outputs for monitoring and protection, including a minimum gap signal for direct protection. Key features: Easy, fast and reliable installation with enhanced filtering of noise and spikes (induced by high excitation currents). Minimum gap signal for direct protection. Accurate and precise results over the full measurement and temperature ranges. Visit this product webpage here.
Housing expansion probes
	The AE219 housing expansion probes use LVDTs for the measurement of casing expansion on the high-pressure end/side of large steam turbines. Key features: Integrated electronics with a 4 to 20 mA output signal. IP55 protection rating (splashproof). Visit this product webpage here.
