Basic Piezoresistive Pressure Sensors
The basic piezoresistive pressure sensors are specifically designed for enhanced compatibility with fluid pressure measurement. These fluid pressure sensors deliver a temperature-compensated, wide-range mV-output signal. With pressure ranges spanning from 70 to 1000 bar and from 1 to 1450 psi. The feature of higher sensitivity, smaller temperature error, and better long-term stability makes the pressure sensing element reliable and stable.

Small Size Pressure Sensors
Small-sized pressure sensors are ideal for applications with stringent dimensional requirements. The advantages of the small pressure elements include their small diameters and reduced heights, providing a compact size that saves space and meets the installation requirements of narrow spaces. Our small-diameter pressure sensors boast diameters ranging from Φ12.6mm to Φ19mm and heights as low as 6.5mm. The compact-size mini pressure sensors are perfect for seamless integration into medical equipment, hydraulic testing, handheld diagnostic devices, and compact industrial probes. Our small-diameter OEM sensor cores feature high media compatibility despite their reduced footprint.

Anti-corrosive Pressure Sensors
Anti-corrosive pressure sensors are specifically designed for measuring pressure in corrosive liquids, fluids, and gases. Industries such as chemical processing, oil and gas, marine, and wastewater treatment often exposure to corrosive substances. Anti-corrosive pressure elements withstand a certain level of corrosive effects. With diaphragm materials such as Tantalum, Titanium, Hastelloy C, and stainless steel 316L, these sensors are well-suited for measuring pressure in challenging environments like seawater or corrosive media, including acid etching, stress corrosion, alkalis, chlorides, chlorine compounds, nitric acid, and sulfuric acid, among others.

Differential Pressure Sensors
Differential pressure elements typically consist of two pressure ports and two sensing elements that measure the pressure difference between the two ports. They are available in various configurations and are compatible with different media types, making them versatile for a broad range of applications. The differential pressure sensor ranges from 350 mbar to 35 bar. Featuring optional external resistors for temperature compensation and an all-welded structure, it is suitable for various fluid media. These water differential pressure sensors and differential air pressure sensors are widely used in industrial process control and other related fields for accurate differential pressure measurement.

Frequently Asked Questions
What is the difference between an OEM pressure sensor element and a pressure transmitter?
A: An OEM pressure sensor element (or core) is the raw sensing component, typically a stainless steel capsule, that provides a millivolt (mV) output. A pressure transmitter is a finished device that includes the sensor element plus conditioning electronics to provide standard industrial outputs like 4-20mA or 0-10V, housed in a complete protective casing.
Do your OEM pressure cores include temperature compensation?
A: Our high-precision pressure cores come with integrated temperature compensation circuits. This ensures accuracy across a wide temperature range, typically from -20°C to +85°C, minimizing thermal zero and span shifts.
Can these pressure sensing elements be used with corrosive media?
A: Yes. For applications involving harsh chemicals or seawater, we offer corrosion-resistant materials such as Tantalum, Hastelloy C, or specialized coatings. Our standard 316L stainless steel isolated diaphragms are suitable for most non-corrosive liquids and gases.
