- Vent Tube: Hollow tube in center of cable to allow for changes in pressure without affecting the accuracy of the readings
FAQs about Sensor Cable
How do I select a cable insulation and jacket that are right for my application?
Many factors come into play here. It is necessary to consider temperature, voltage, abrasion resistance, flexibility, and chemical compatibility. Galaxy often works with customers to learn about where the cable will be used and what its function will be to help select the materials for optimum performance. See table above describing various choices/options.
What is the reason for a vent tube in a cable?
The vent tube can be made of either nylon or polyethylene and runs the length of the cable down its core. It allows for changes in atmospheric pressure so as not to affect the pressure reading in gauge type sensors.
