Features

• Long operating life with a non-clog flush diaphragm tip for harsh applications
• Eliminates particulate or water droplets from entering the transducer using maintenance-free filter
• Suits harsh environments with choice of polyether polyurethane or ETFE cable materials for excellent chemical compatibility
• Increased life with lightning and surge protection utilizing dual arrestor technology, grounded to case, eliminating both power supply surges and lightning ground strike transients (surge protection is not guaranteed and is not covered by warranty)
• Meet application requirements with narrow body design allows the FBLT to fit into stilling wells and narrow installations
• Unit holds up in aggressive fluids with robust FKM fluoroelastomer diaphragm that is PTFE coated for a stick-resistant surface
• Avoid product leaks typically cause by oil or grease with diaphragm cavity that is filled with gel
• Flexible installation options with NPT connection to rigidly install in a pipe/conduit or use the A-625 hanging loop to attach a chain to remove from the installation

Options

• Cables can be ordered shorter or longer in polyurethane or ETFE.
• Other ranges are available and can be ordered in psi, ft w.c., or m w.c.
• NPT connection. Add suffix -NPT, for a 1/2" NPT connection to connect conduit, piping, or cable hanger, 316 SS.
• FC Factory calibration certificate

Approvals

• CE Approval
• RoHS Letter of Compliance

Questions

Question

Our client has an MBLT pressure transmitter that appears to be malfunctioning due to scale buildup. The transmitter is installed to measure leachate level in a one-year old municipal sanitary landfill. What can we use to remove scale from the transmitter without damaging the transmitter?

Answer

If the issue is due to build-up which consequently plugs the small sensing holes, you might take a look at our PBLT2 or FBLT series. They are both more rugged and designed for sludge and slurries, whereas the MBLT and SBLT2 are better suited for cleaner applications such as ground water and wells.
