The Multipoint Blast Eye system is the latest Blast Eye device designed for use with hot-hole blasting applications. It is designed to measure multiple temperatures along a single sensor cable and is designed to be economical and reusable with only the sensor cable being disposable. The system was designed and is manufactured in South Africa, and consists of two elements:
- The Reader unit
- Sensor cable
The Reader Unit
The reader unit is an electronic device that, when connected to a sensor cable, measures the temperature at each sensor location and displays the status in an easy-to-understand manner. The status is displayed on an LCD display as well as other audio and visual indicators. The readers have the following features:
- The units are reusable
- Low and high temperature alarm thresholds (can be set according to customer requirements)
- Powered by replaceable AA batteries with a typical life of over 80 hours
- Low battery alert
- Support up to 12 sensors
- Easy to understand audio and visual alarms
- Robust design, including a spike for inserting into the ground
- Individually barcoded for asset and use tracking
- User friendly operation
The Sensor Cables
The sensor cables consist of a connector together with a specified length of cable and a specified number of sensors along its length. As these cables are fed down the hole to be blasted, they are disposable, and as such are designed to be as economical as possible. Each cable has an additional 2m to allow the reader to be placed away from the hole as well as a tail of 2m on the end to allow a weight to be attached if required, or for the cable to be tied into a blasting sleeve. These cables can be customized in any number of ways, so please contact us with your configuration requirements. The sensor cables feature the following:
- Temperature measurement range of -55°C to 125°C
- Sensors are over-molded for robustness and waterproofing
- Manufactured to order: Standard sensor spacing is 5m, but can be customized according to customer requirements
- Colour coded for easy identification
- Customizable up to 60m and 12 sensors
