High-precision column-type pressure sensor

Main Features:

This series comprises high‑precision column‑type pressure sensors specially developed for the commercial vehicle, construction machinery, and heavy‑duty vehicle sectors. Featuring an all‑stainless‑steel column‑type housing with standard hydraulic connectors, these sensors incorporate a high‑accuracy piezoresistive pressure sensing element and an integrated signal‑conditioning circuit. They can be directly mounted in hydraulic systems, brake lines, and fuel systems to enable precise measurement of hydraulic oil pressure, brake pressure, and fuel pressure, making them widely suitable for meeting the powertrain, hydraulic system, and safety‑control requirements of commercial vehicles, construction equipment, and specialized vehicles.

Core Features

High-strength column-type structure, designed to withstand heavy-duty vehicle operating conditions. It features an all-stainless-steel column-type housing, offering excellent resistance to impact, vibration, and high pressure. It can withstand the heavy loads, intense vibrations, and harsh environmental conditions of heavy vehicles, ensuring a long service life.
High precision and wide-temperature-range stability : Featuring a built-in high-precision piezoresistive pressure sensing element and a temperature-compensation circuit, it delivers stable, high‑accuracy pressure measurement across a wide temperature range of –40°C to +150°C, providing reliable data support for automotive ECUs and control systems.
Standard hydraulic fitting design for easy installation. It employs standard hydraulic fittings, enabling direct connection to the hydraulic lines of commercial vehicles and construction machinery without the need for additional adapters, thus simplifying installation and maintenance and ensuring compatibility with the hydraulic system specifications of mainstream heavy-duty vehicles.
Media resistance and high protection rating : The stainless steel probe exhibits excellent resistance to corrosion by hydraulic oil, brake fluid, fuel, and other media, with a high ingress protection rating that effectively prevents the ingress of moisture and contaminants, making it suitable for long-term operation in the complex fluid environments found in vehicles.
