Description

This enclosure allows a vented depth sensor to be vented close to the monitoring point, whilst preventing moisture, or debris, getting into the vent tube of the sensor. The enclosure has one gland to allow for the depth sensor and a second for the signal cable going back to the monitoring equipment. This allows an expensive cable to the sensor to be long enough to exit the media, whilst running a standard lower cost cable back to the monitoring equipment.

Advantages of local venting:

• Accuracy: It improves the accuracy of the vented sensor by compensating at the monitoring location and not at a higher elevation, or a long distance away.
• Vent Tube Blockage: Shorter vented cable lessens the chance of the vent being blocked due to cable pinching, or debris getting into the tubing.
• Reduced Cable Cost: Allows the use of standard, less expensive cable for the long run back to a control device.
• Protection: The enclosure can also protect the sensor connections from moisture and other environmental factors.
• Ease of Maintenance: Venting is done at a local point, so maintenance is easier.
• Cable Damage: If creatures chew through the cable, it is more likely to be the low cost cable rather than the expensive cable of the sensor
• Sensor Damage: If the sensor is damaged, it is just the sensor that needs to be replaced with short cable.
