Good value for industrial use
We installed these in our water treatment facility. They work well, though the installation manual could be more detailed. Overall satisfied with the performance.

Works as described
Solid sensor for air pressure applications. It took a day to calibrate perfectly with our system, but once set, it has been flawless.

Durable and reliable
Been using this for oil pressure monitoring in a harsh environment for three months. No corrosion or drift in values. Highly recommended.

Best ceramic sensor we've tried
We switched from metal sensors to these ceramic ones to avoid corrosion issues. This model has exceeded our expectations in longevity and accuracy.
Q: What is the maximum temperature this module can withstand continuously?
A: The CJ18-20A is rated for continuous operation up to 135°C. Exposure to temperatures beyond this limit may affect accuracy or damage the sensor.
Q: Is this sensor compatible with corrosive chemicals?
A: The ceramic material offers excellent resistance to many corrosive substances, but we recommend checking the chemical compatibility chart for your specific fluid before installation.
Q: Does this come with a calibration certificate?
A: Standard units include a factory test report. A full ISO-traceable calibration certificate is available as an add-on option at checkout.
Q: Can I get this with an M12 electrical connector?
A: Yes, we offer optional M12 connectors. Please select the appropriate variant from the dropdown menu or contact us directly for a custom order.
Q: What is the lead time for bulk orders of 500 units?
A: For orders of 500 units or more, the typical lead time is 2-3 weeks depending on current stock levels and customization requirements.
