Works as described for oil pressure
No issues with compatibility regarding engine oil. The response time is quick. Documentation could be slightly more detailed regarding wiring diagrams.

Robust build quality
The ceramic housing feels incredibly durable. We use these for compressed air systems in a dusty environment, and they have held up perfectly for six months.

Good value for water level sensing
Using it in a water tank application. It works well and the corrosion resistance is excellent. Only giving 4 stars because the threading required a specific adapter for our setup.

Excellent industrial grade sensor
We tested this against a calibrated lab standard and it was spot on. Highly recommend for anyone needing a reliable resistive pressure module.

Accurate and reliable
Replaced several faulty sensors with the CJ18-20A model. The accuracy is consistent across all units we purchased. Great for OEM integration.

Perfect for hydraulic monitoring
Installed this sensor on our hydraulic press line. The ceramic element handles the pressure spikes without any drift. Very stable readings compared to our old units.
Q: Does this come with a mating connector?
A: The standard package includes the sensor module only. Mating connectors and cables are available as separate accessories in our store.
Q: Can I use this for high-temperature steam?
A: While the sensor handles up to 135°C, direct exposure to high-pressure steam may require a cooling siphon or diaphragm seal to protect the internal elements. Please contact us for steam-specific configurations.
Q: Is this sensor compatible with diesel fuel?
A: Yes, the ceramic material is chemically resistant and suitable for diesel fuel applications within the specified pressure and temperature ranges.
Q: What is the warranty period for this item?
A: This product comes with a standard 12-month manufacturer warranty covering defects in materials and workmanship under normal use.
Q: What is the maximum burst pressure for the CJ18-20A?
A: The burst pressure is typically 3 times the full-scale range. For a 20 Bar unit, this would be approximately 60 Bar, but please consult the specific datasheet for your ordered range.
