Series-SBLTX
UL Certified Submersible Level Transmitters - Piezoresistive, 316 SS Housing
- Meets application requirements with slim design with bullet nose design which protects the diaphragm from damage
- 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) on SBLT2 models
- Eliminates particulate or water droplets from entering the transducer using maintenance-free filter
- Peace of mind with UL approved intrinsically safe on SBLTX models for use in hazardous locations when used with proper barrier
- Decrease ownership cost with durable, 270 lb tensile strength shielded and vented cable and excellent chemical compatibility
- Flexible installation options with NPT connection to rigidly install in a pipe/conduit or use a A-625 hanging loop to attach a chain to remove from the installation
- Minimal downtime with standard 72 hour lead time

Supported Applications
The Series SBLTX Submersible Level Transmitter is a piezoresistive sensing device designed to measure liquid height above a reference point in a tank relative to atmospheric pressure. The series supports applications involving compatible liquids, including air economizers, groundwater monitoring, environmental remediation, and water tanks.
Operating Conditions & Performance
The Series SBLTX features an accuracy of ±0.25% FS with a response time of 50 ms. The compensated temperature range is -4 to 176°F (-20 to 80°C). Process and ambient operating limits depend on the cable type: ETFE cables support -4 to 176°F (-20 to 80°C), while Polyurethane cables support -4 to 149°F (-20 to 65°C). The thermal effect is less than ±0.02% FS/°F.
Power requirements are specified as 10-28 VDC with a maximum loop resistance of 900 Ω at 30 VDC. The output signal is 4-20 mA DC, 2-wire. The pressure limit is rated at 2X FS. Mounting orientation requires the unit to be suspended in the tank below the level being measured.
Configuration Options
The Series SBLTX offers configurable options for measurement ranges and cable lengths, with additional configurations available upon consultation with the factory. The series supports a 316 SS housing with wetted materials including 316L SS body components, PVC bullet nose, Polyether polyurethane or ETFE cables, and Fluoroelastomer seals.
Key configurable dimensions include:
- Cable Type: Standard Polyurethane (blank) or ETFE (-ETFE).
- Intrinsic Safety Options: Available with -ATEX designation for intrinsically safe configurations.
- Process Connections and Mounting Accessories: Includes options such as 1/4" NPT male (-P1), 1/4" NPT female (-P2), 1/4" BSPT male ISO 228 R (-P3), 1/4" BSPT female ISO 228 RC (-P4), and a 3/4" clean-out type (-P11).
- Electrical Connection: Wire pigtail with shielded, vented cable featuring a ventilation tube to compensate for atmospheric pressure changes.
The series is UL listed for use in Hazardous (Classified) Locations using Intrinsic Safety "ia" protection. Approvals include CE and UKCA. Specific classifications cover Class I Div. 1 Groups A, B, C, D; Class II Div. 1 Groups E, F, G; Class III Div. 1; Class I Zone 0 AEx ia IIC T4 Ga; Zone 20 AEx ia IIIC T135°C Da.
Key Product Differences
The Series SBLTX is distinguished from the non-hazardous location Series SBLT2 by its intrinsic safety certifications and specific power requirements. While both series share a piezoresistive sensing element in a 316 SS housing, the SBLTX operates on a 10-28 VDC supply compared to the SBLT2's 10-30 VDC range.
Temperature limits also vary by cable type and series. The Series SBLTX supports an extended low-temperature limit of -4°F (-20°C) for both ETFE and Polyurethane cables, whereas the Series SBLT2 starts at 0°F (-18°C). Additionally, the Series SBLTX does not include lightning and surge protection features found in the Series SBLT2. The overall length ranges from 7-3/16 [182.56] to 7-7/16 [188.91], with a diameter of Ø1 [Ø25.40].
