Product Description:
HLR 750 Series of 3/4 inch diameter high reliability LVDT position sensors are specifically designed for use in gas turbine environments. These hermetically sealed AC-LVDTs are listed for Class I Division 1 intrinsically safe or Class I Division 2 non-incendive environments by Underwriters Laboratories. Although these ratings share a common LVDT, each set of approvals retains specific operating requirements [Ambient Temperature: -58°F to 212°F (100°C), Maximum Input: 6 V rms @ 2.5 kHz, and ONLY WHEN INSTALLED PER MACROSENSORS 011600000113 Standards] -or- [Ambient Temperature: -58°F to 300°F (150°C)], respectively. Constructed entirely of stainless steel for environmental robustness, they feature a through-bore design which makes the LVDTs’ cores accessible from both ends for better mechanical support and core guidance and facilitates clean-out in dusty or dirty locations. An HLR LVDT’s lead wires exit through a radially mounted 1/2-14 NPT male threaded conduit fitting for easy attachment to an explosion-proof junction box as well as rigid or flexible conduit.
