FCI liquid level switches ensure high-reliability liquid level and interface sensing with the FLT93 Series. No moving parts, SIL 2 rated, and engineered for Eastern Canada’s harshest industrial processes
The FCI FLT93 Series is the most robust solution for simultaneous level, flow, and temperature monitoring in Eastern Canada’s harshest industrial processes. With no moving parts to wear or foul, the FlexSwitch provides a “set-and-forget” reliability that mechanical switches simply cannot match.
Pump Protection: Immediate dry-run detection to prevent bearing and seal damage.
Interface Control: Precise detection between water/oil or liquid/foam layers.
Safety Systems: SIL 2 rated for critical high/low level alarms in chemical and nuclear environments.
Drain Line Monitoring: High-sensitivity detection of even the smallest liquid presence.
The FLT93 utilizes advanced thermal dispersion technology. By measuring the heat transfer difference between a heated and a reference RTD, it provides a trip-point sensitivity that remains stable regardless of changes in process pressure or density.
Operating Range: -40°C to 454°C (-40°F to 850°F).
High Pressure Integrity: Tested to 3500 psig (240 bar).
Materials: Standard 316L Stainless Steel; optional Hastelloy C or Titanium for corrosive media.
Dual-Relay Versatility: Two independent 6A SPDT relays, field-configurable for any combination of level, flow, or temperature.
Temperature Compensation: Unlike basic thermal switches, the FLT93 stays accurate even if your process temperature swings by 100°F.
Universal Power: One unit supports 24 Vdc, 115 Vac, or 230 Vac, simplifying your spare parts inventory.
Ruggedized Construction: The all-welded thermal sensing element is designed for decades of service in high-vibration and high-pressure environments.
If you are looking to integrate the FLT93 into your local infrastructure, we recommend these primary configurations:
The FCI FLT93S FlexSwitch is the heavy-duty version designed for high-temperature and high-pressure applications. It is the ideal choice for heavy industrial plants requiring maximum durability and SIL 2 compliance.
For applications requiring a faster response time in lighter liquids or gases, the FCI FLT93F FlexSwitch features a smaller sensing element that reacts quickly to rapid changes in the process media.
