Import 5 Psi-D-4v-Mil Amplified Middle Pressure Sensor — Buy in wholesale FOB from Supplier in China

The 5 PSI-D-4V-MIL from Week Technology is an amplified, temperature-compensated piezoresistive pressure sensor rated for ±5 psi differential measurement with ratiometric 4 volt output. The device employs a silicon micromachined stress concentration enhanced structure with ASIC-based internal compensation, packaged in a housing designed to reduce parasitic stress and strain from mounting. Supply voltage range spans 4.5 to 5.5 volts with output scaling proportionally, and operating temperature compensation covers -40 degrees C to +125 degrees C. Each unit ships calibrated for zero and span, though calibration traceability to national standards is not specified in the source data.

Construction centres on a silicon sensing element with piezoresistive elements diffused into a micromachined diaphragm; stress concentration features amplify strain at the gauge locations to improve sensitivity and linearity. The proprietary package technology referenced by Week Technology addresses thermal expansion mismatch between silicon die and housing material, a common failure mode in uncompensated sensors. Working fluid compatibility is limited to non-corrosive, non- professionally ionic media: dry air, inert gases and similar clean environments. Exposure to moisture, saline atmospheres or aggressive chemicals will degrade performance and void implied reliability.

Primary applications sit in medical instrumentation, environmental control systems and HVAC equipment where clean, dry pressure measurement at modest ranges is required. The MIL suffix suggests military-grade packaging or screening, though buyers should confirm whether this denotes full MIL-STD-883 environmental testing or simply a package style. Ratiometric output simplifies interface with ADC reference circuits, as output span tracks supply voltage. Buyers must confirm with Week Technology the exact calibration certificate provided, long-term drift specifications, and whether lot acceptance testing includes thermal cycling or mechanical shock per MIL-PRF-38534.

Week Technology Ltd. is headquartered at 16 Floor, Building 3, Zhongke Mansion, Shenzhen 518067, Guangdong Province, placing it within the Nanshan technology district corridor. The supplier holds imported tier and harbour trust tier classifications. Response metrics show 0.00 response rate with zero average response hours, indicating potential delays in initial enquiry handling. The company specialises in pressure sensing technology with proprietary packaging and ASIC compensation capabilities, positioning within the component supply chain for medical and environmental equipment manufacturers.

No employee count, factory ownership details, revenue, client roster or specific quality certifications appear in the source profile. The address at a multi-tenant office building rather than a dedicated manufacturing campus suggests design and sales functions may be centralised there, with production potentially at subcontractor or partner facilities. Buyers should verify whether Week Technology performs wafer fabrication, sensor assembly and calibration in-house, and whether they hold ISO 13485 for medical device components or ISO/IEC 17025 for calibration laboratory accreditation.
