815LT Submersible Smart Level-Pressure Transmitter

Models: 815LT
Ranges: 0-35 ft. w.c. to 0-575 ft. w.c.
Turndown: 5:1
Certifications: Unit: ATEX
Warranty: 3 Year

The 815LT submersible smart level-pressure transmitter is a rugged, compact, loop-powered instrument that is ideally suited for applications where the transmitter is frequently or continuously submerged in fluids. The transmitter’s vented cable design allows for reference to atmospheric pressure at all times in order to obtain highly accurate pressure or level readings. The 815LT is designed to measure gauge pressure or hydrostatic pressure for level output.

The 815LT is easily configured using HART®7 communication protocol and Modbus RTU Serial Communications. The transmitter can also be set by placing a magnet on the outside of the housing in order to reset the zero and span.

  • Compact, 316 Stainless Steel construction
  • IP68 housing Submersible up to 1200 feet
  • Cage option to protect sensor from solids and prevent build up
  • LCD remote mounted display option
  • HART®7 & Modbus RTU (RS-485) Communications available
  • Vent tube for reference to atmospheric pressure
  • 1-5 VDC (Low-Power) Mode of Operation
  • Configurable Normally-Open Solid-State Switch Output (SPST)
  • ±0.10% (URL) Continuous Output Accuracy
  • Turndown: 5 to 1
  • Zero and Span Magnetic Targets Located on Casting
  • EMC (EMI/RFI) Protection

Submersible Hydrostatic Level Transmitter

Submersible Hydrostatic Level Transmitter

Models: 510LT, 510SF
Ranges: 10 to 463 ftwc (3 to 140m)
Certifications: Unit: ATEX
Warranty: 1 Year

The 510 submersible level transmitter is an economical, loop-powered transmitter that accurately and reliably measures liquid level – especially in deep sump or well applications (200 to 300 feet). It’s compact size is ideal for feeding into smaller pipe sizes. The 510 features a corrosion-resistant stainless steel housing, Viton seals and a polyurethane cable jacket allow for compatibility with most liquids.

  • Nose cone with NPT(M) connection or flush sensor design
  • Unspliced cable lengths up to 3,000 ft.
  • Ranges from 10 to 463 ftwc
  • Compact, 316SS housing

SOR submersible transmitters indicate level by continuously monitoring the head pressures of the liquids, using high performance pressure sensors. SOR submersible transmitters have a corrosion resistant 316 stainless steel housing and a high-density Polyethylene (HDPE) cable jacket for compatibility with most liquids. PVC self-flushing nose cones on the 815LT and 510LT prevent clogging and are easily removed for calibration or rigid mounting. The transmitters are vented at the surface (through a tube in the cable) to reference atmospheric pressure.

  • Rugged
  • Economical
  • Compact
  • Prevents clogging
  • Easily removable
