Kind Tips
1. Temperature Limitations
The 19mm isolated pressure sensing cell is rated for maximum temperatures of 125°C (with high-temperature versions available to 150°C). Exposure to higher temperatures-such as near furnaces or exhaust systems-can permanently damage internal components.
2. Pressure Range Requirements
Operate only within the specified pressure range. Overpressure events exceeding 1.5x rated range may cause permanent deformation of the sensing diaphragm, resulting in signal drift, measurement errors, or complete failure.
3. Installation & Handling
Protect the pressure port during transportation and installation to prevent contamination by dirt, debris, or particulate matter that could compromise measurement accuracy or damage the diaphragm.
FAQ
Q: What is the primary advantage of an isolated pressure sensing cell?
A: The key advantage is media isolation. A stainless steel isolation diaphragm separates the process media from the internal sensing chip, protecting it from corrosive, viscous, or particulate-laden media. This significantly improves long-term reliability and accuracy in harsh environments.
Q: Can you customize the electrical connection interface?
A: Yes. We provide various options such as connectors, flying leads, or cable outlets to match your system's design requirements.
Q: How should I protect the sensor from overpressure?
A: Avoid exceeding 150% of the rated pressure range. For applications with pressure spikes or pulsation, we recommend installing a snubber or pressure limiter.
Q: What is the warranty period and what does it cover?
A: The product has a one-year warranty. During this period, we will repair or replace any product quality issues and provide ongoing strong technical support.
