FLD-SSM-H Control and Monitoring Device for Panel Mount

FLD-SSM-H is a high-performance all in one monitoring module and controller built into one budget conscious package. Designed for detecting leaks of refined products or crude oil in extreme environmental conditions. The device is a DIN-rail mounted standalone leak detection controller. The maximum sensor length is limited to 100ft/30m per FLD-SSMH.

These sensor modules (FLD-SSM) offer industry-standard output communications:

  • analog outputs (0-10V)
  • dry contacts (2 SPDT Relays)
  • RS-485 serial interface
  • current loop (4-20mA)
For hazardous locations applications, the sensor cable FLD-HSC or FLD-O2W-SP sensor probe will be wired to the sensor module through a Zener barrier, with FLD-SSMH module installed in an area approved enclosure.
