Overview
The KULITE BG Series solid-state pressure transducers are high-stability, silicon-based piezoresistive sensors engineered for precision static and dynamic pressure measurement in demanding environmental and industrial monitoring applications. Unlike traditional strain-gauge or capacitive transducers, the KULITE BG series utilizes a monocrystalline silicon diaphragm with ion-implanted piezoresistors, providing exceptional linearity, hysteresis-free response, and long-term zero stability—critical attributes for continuous gas pressure monitoring in fixed-location environmental stations, stack emission systems, and confined-space ventilation safety networks. These transducers operate on the principle of piezoresistive effect: applied pressure induces mechanical strain in the silicon diaphragm, resulting in a proportional change in electrical resistance measured via a Wheatstone bridge configuration. Designed for integration into OEM gas detection and alarm platforms, the BG series delivers calibrated analog output (typically 0–5 VDC or 4–20 mA) compatible with standard PLCs, SCADA systems, and data loggers compliant with IEC 61000-6-2/4 electromagnetic immunity standards.
Key Features
- Silicon-on-sapphire (SOS) or silicon-on-insulator (SOI) sensing element architecture for superior thermal stability and corrosion resistance
- Full-scale pressure ranges from 0–1 psi to 0–5,000 psi, with standard configurations optimized for low-range environmental gas pressure monitoring (e.g., 0–100 psi, 0–250 psi)
- Operating temperature range: –55 °C to +175 °C (dependent on model and housing), enabling deployment in outdoor enclosures, HVAC ducts, and industrial exhaust manifolds
- Hermetically sealed stainless steel (316L) or Inconel housings rated to IP67/NEMA 4X for dust and moisture ingress protection
- Compensated accuracy: ±0.25% FS typical (including nonlinearity, hysteresis, and repeatability) over compensated temperature range (–40 °C to +85 °C)
- Integrated temperature sensor (PT1000 or digital I²C output) for real-time thermal compensation in software-defined calibration routines
Sample Compatibility & Compliance
The KULITE BG series is suitable for clean, dry, non-corrosive gases—including ambient air, nitrogen, carbon dioxide, methane, and compressed instrument air—as well as mildly aggressive media when configured with optional Hastelloy C-276 diaphragms. It is not intended for use with halogenated refrigerants, hydrogen sulfide, or condensing vapors without protective isolation systems. All BG-series transducers comply with RoHS 2011/65/EU and REACH SVHC regulations. For use in safety-critical gas alarm systems, models can be supplied with SIL 2 certification per IEC 61508 and ATEX/IECEx Zone 1 approval (with appropriate barrier or intrinsically safe interface). Documentation packages include traceable NIST-traceable calibration certificates and full material declarations required under EU MDR Annex II for integration into certified environmental monitoring hardware.
Software & Data Management
While the BG series operates as a stand-alone analog/digital transducer, it integrates seamlessly with industry-standard data acquisition ecosystems. Raw output signals interface directly with programmable logic controllers (PLCs), distributed control systems (DCS), and EPA-compliant continuous emission monitoring systems (CEMS). When paired with York Instrument’s proprietary configuration utility (available for Windows/Linux), users can perform field recalibration, linearization coefficient updates, and temperature-compensation profile loading via RS-485 Modbus RTU or USB-C interface. Audit trails, calibration history, and firmware version logs are stored internally with timestamped metadata—supporting GLP/GMP documentation requirements and FDA 21 CFR Part 11 compliance when deployed in regulated environmental testing laboratories.
Applications
- Static pressure monitoring in HVAC airflow balancing and duct leakage testing per ASHRAE Standard 111
- Differential pressure measurement across HEPA filters and scrubber beds in air quality control systems
- Stack gas velocity estimation using pitot-static tube arrays coupled with KULITE differential pressure modules
- Low-pressure monitoring in landfill gas collection headers and biogas upgrading skids
- Calibration reference standards for portable gas detectors undergoing ISO 17025-accredited verification
- Long-term barometric compensation in ambient VOC monitoring networks (e.g., PID/FID-based analyzers)
FAQ
Can the KULITE BG series be used for explosive gas environments?
Yes—when specified with ATEX/IECEx-certified housings and connected through approved intrinsic safety barriers, select BG models meet Zone 1 hazardous area requirements.
Is NIST-traceable calibration included with shipment?
Each unit ships with a factory calibration certificate referencing NIST-traceable standards; optional on-site calibration verification services are available through York Instrument’s global service network.
What is the expected service life under continuous operation?
With proper installation and environmental protection, mean time between failures (MTBF) exceeds 100,000 hours per MIL-HDBK-217F prediction models for industrial-grade variants.
Do BG-series transducers support digital communication protocols beyond analog output?
Yes—RS-485 Modbus RTU, CAN bus (ISO 11898-2), and I²C interfaces are available as factory-configurable options on most BG submodels.
Are custom pressure ranges or electrical outputs available?
York Instrument offers engineering support for application-specific configurations including non-standard full-scale ranges, dual-output hybrids (analog + digital), and custom mounting flanges per ANSI B16.5 or DIN 11851 specifications.
