Import Auto Pressure Transducer (Ceramic) (Apt) — Buy in Bulk from Supplier in Taiwan

The Auto Pressure Transducer (Ceramic) from Avertronics Inc. employs a ceramic capacitor sensing element for precision pressure measurement in automotive and industrial applications. Unlike piezoresistive designs, ceramic capacitive transducers offer inherent corrosion resistance, minimal hysteresis, and excellent long-term stability in media such as refrigerant, engine oil, and brake fluid. Avertronics integrates all signal conditioning circuitry within the compact sensor housing, reducing interconnect complexity and electromagnetic interference susceptibility. The ceramic membrane separates the pressure medium from the electronics, a construction particularly suited to aggressive fluids and wide temperature excursions.

Ceramic capacitor pressure sensors typically use alumina (Al2O3) or zirconia-based ceramics for the sensing membrane, with capacitance change proportional to diaphragm deflection under pressure. Avertronics' design incorporates onboard ASIC signal processing to deliver calibrated analogue or digital output (voltage, current, or protocol such as SENT or LIN) directly from the sensor head. The monolithic ceramic element eliminates welded or bonded joints that fatigue in cyclic pressure applications. Standard pressure ranges for automotive APT products span 0.5 to 50 bar, with burst pressure typically 3-4 times rated full scale. Overpressure and reverse-pressure protection are integrated at the mechanical stop and electronic clamp levels.

Primary buyers include automotive Tier-1 and Tier-2 suppliers producing engine management systems, HVAC control modules, transmission hydraulics, and industrial process equipment. The sensor suits any application requiring media compatibility with aluminium, ceramics, and fluorosilicone or EPDM seals. Buyers should confirm with Avertronics the exact output protocol, pressure range, connector type, and electromagnetic compatibility test scope (CISPR 25, ISO 11452) for their vehicle programme. Packaging, minimum order quantities, and lead times are not specified in the source data and require direct enquiry.

Avertronics Inc. is headquartered at No.10, Gongyequ 19th Rd., Nantun Dist., Taichung 40850, Taiwan, placing it within one of the island's established electronics manufacturing clusters. The supplier carries an 'imported' tier and 'harbor' trust tier designation. The response rate shows 0.00 percent with zero average response hours, indicating that platform messaging mayisb unreliable and direct outreach is advisable. No information is provided on founding year, employee count, production floor area, revenue, or named automotive OEM approvals, so buyers must request these details independently.

The company focuses on pressure sensing technology for automotive and industrial markets, with this ceramic capacitive transducer representing a core product line. The source description positions Avertronics as offering flexible supply arrangements, though no minimum order quantities, price bands, or lead times are verifiable from the data provided. The profile does not disclose specific quality certifications such as IATF 16949, ISO 9001, or AEC-Q100 qualification status for the sensor. Buyers should verify whether Avertronics operates an automotive-grade production line with statistical process control, and whether they provide PPAP documentation for new sensor programmes.
