Good industrial sensor

Works exactly as described. The IP68 rating holds up well against dust and water spray in our loading dock environment. Delivery was faster than expected.

Solid build quality

The construction feels very robust. It has survived a harsh winter outdoors without any issues. I took off one star only because the cable could be slightly longer for our specific pit setup, but otherwise excellent.

Perfect for heavy logistics

We installed four of these sensors on our new truck scale last month. The calibration was straightforward, and the readings have been incredibly stable even with frequent heavy traffic. Highly recommended for industrial use.

5 FAQ

Q: Can this be used in freezing temperatures?

A: Absolutely. The operating temperature range is -35°C to +65°C, so it is designed to function correctly in freezing environments provided it is installed according to guidelines.

Q: Is this sensor compatible with most standard junction boxes?

A: Yes, the QS-D40t uses standard wiring color codes and impedance values, making it compatible with the majority of commercial weighbridge junction boxes and indicators.

Q: How many sensors are typically needed for a standard truck weighbridge?

A: Most standard truck weighbridges require either 4, 6, or 8 sensors depending on the platform length and design. Please consult your scale blueprint or contact our engineering team for a specific recommendation.

Q: Do you provide calibration certificates with the unit?

A: Each sensor undergoes factory testing, and a test report is included in the package. For official legal-for-trade calibration, local certified technicians must verify the complete scale system after installation.

Q: What is the warranty period for this model?

A: This sensor comes with a standard 2-year manufacturer warranty covering defects in materials and workmanship under normal operating conditions.
