Product Introduction
-
Our Isolated Pressure Sensing Cell is a high-performance piezoresistive pressure sensor featuring an all-metal isolation structure. Utilizing a precision silicon sensing die housed in a stainless steel enclosure (Ø12.6mm), it transmits media pressure through an isolated diaphragm to accurately convert pressure into stable electrical signals and effectively protecting the internal sensing die from corrosive and viscous media.
-
Each sensing cell undergoes rigorous testing and calibration to ensure exceptional reliability across a wide pressure range (0-100kPa to 60MPa), with an operating temperature of -40°C to 125°C and rapid 1.0ms response time.
-
This 12.6mm isolated pressure sensing cell is designed to meet the demanding requirements of test and measurement, hydraulics, and process control, achieving extremely low drift and stable performance.

Kind Tips
- Media Compatibility Check
Always ensure the measured media is chemically compatible with the sensor's wetted materials (typically 316L Stainless Steel isolation diaphragm). Incompatible media can cause corrosion and sensor failure.
- Do Not Exceed Pressure Limits
The applied pressure must never exceed the sensor's rated pressure and especially its burst pressure limit. Avoid pressure spikes or water hammer effects in the system, which can cause irreversible damage.
- Operating Environment Considerations
Ensure the sensor operates within its specified temperature range (e.g., -40°C to 125°C). Avoid rapid thermal shock, which can affect measurement accuracy and potentially damage the sensor.
- Proper Handling, Transportation & Storage
Handle with care to prevent mechanical shock or impact that could affect calibration.
For long-term storage, keep the sensor in its original packaging in a dry, cool environment free of corrosive gases. Regular checks are recommended.
FAQ
Q: What is an isolated pressure sensor, and why is it better than a non-isolated type?
A: An Isolated Pressure Sensor, like our Isolated Pressure Sensing Cell, features a physical barrier (typically a stainless steel diaphragm) that separates the process media from the internal sensing element. This isolation is superior for measuring corrosive or viscous media, as it protects the sensor from damage, ensures long-term stability, and prevents media contamination, which is a common point of failure in non-isolated sensors.
Q: What is the operating temperature range of your isolated pressure sensing cell?
A: The operating temperature range of a pressure sensor refers to the temperature range within which the sensor can function normally and produce accurate, reliable measurements. Operating temperature is a critical parameter because it affects the sensor's internal components, such as the sensing element and electronic components. If temperatures exceed the specified operating range, sensor performance may be compromised, measurements may become inaccurate or unreliable, and in severe cases, the sensor may fail.
Q: Is this pressure sensor compatible with my specific media?
A: Yes, our sensing cell is designed for harsh media compatibility. The all-metal isolated diaphragm is made from 316L stainless steel, which is highly resistant to a wide range of corrosive media, including water, oils, most chemicals, and viscous fluids.
