Micromate External Trigger Cable

The External Trigger Cable can be used to remotely trigger a Micromate unit or to synchronize the triggering of up to six units. At the end of the External Trigger Cable there are two leads; a change in the state of these leads will cause the Micromate unit to start monitoring. They can be connected to start and once that connection is broken, the unit will start to record, or they can be separated initially and when they make a connection the Micromate will start to record. The External Trigger Cable connects to the auxiliary port (factory installed option) on the Micromate unit and comes complete with a 2 m (6.5 ft) cable. The External Trigger Cable can also be used with Instantel’s 100 ft or 250 ft extension cables.

Application Examples

  • Twist the two leads together and use an energy source, such as a blast, to break the two leads apart, triggering the Micromate unit to start recording. Typically, the two leads are tied together and then wrapped around a detonator or explosive before being lowered into a borehole. When the explosives detonate, the two leads on the external trigger cable will break apart and automatically trigger the unit to start recording. This will give you time 0 or when the blast started. As each hole in the blast design is detonated it will create a peak in the waveform. Using time 0, you can calculate the time between each peak and compare it to the time delays between each hole and row in your blast design. You can then use this data to help you design a more controlled and precise blast.
  • Velocity propagation of the rock is a key part of blast design. Using the External Wire Trigger Cable you can measure accurate velocity propagation values from the rock you are blasting. The External Wire Trigger Cable can be used to synchronize event recordings on up to six monitoring units. After connecting an External Trigger Cable to each unit and tying their leads together, when one Micromate unit is triggered and begins recording, the other connected Micromate units will also begin to record. The time it takes for the vibration to travel from one Micromate unit to the next can be used to get an accurate velocity propagation value.
Micromate Remote Alarm Controller

The Remote Alarm Controller is used to indicate when the Micromate unit has exceeded the trigger levels you’ve configured. When you connect lights or sirens to the Remote Alarm controller, you can receive audible or visual alerts that your activities are near or have exceeded the trigger levels. Trigger levels on the Micromate can be set based on your project’s requirements and can be different for each job. With an early warning system, you can manage vibration or noise inducing activities before concerns develop.

The Remote Alarm Controller connects to the auxiliary port on the Micromate monitoring unit, a factory installed option. The auxiliary port can be installed on existing Micromate units when they are returned to Instantel for calibration. The Remote Alarm Controller comes complete with a 2 m (6.5 ft) cable but it can also be used with Instantel’s 30 m (100 ft) or 75 m (250 ft) extension cables.

Micromate Portable Printer

Micromate Portable Printer

Some monitoring applications require hard copy reports to be printed in the field. The Micromate provides a USB interface which can be used to connect an external printer for in-field printing. The Portable Printer is battery operated and can easily be transported to the site and connected to the Micromate to print the event reports right in the field.

Micromate Protective Boot and Cover

The protective boot and cover have been specifically designed to protect the Micromate unit and provide flexibility when mounting the unit. The robust protective boot and separate protective cover offer an easy-on, easy-off installation. The Micromate Boot can be mounted to a wall permanently and then when needed, the Micromate can easily be fit into the Boot.

The clear protective cover has been designed to hinge at either end. It protects the Micromate’s screen against damage and the elements while offering the operator easy access to the unit’s touch screen. The cover panel is designed to prevent water from pooling on the unit. Each end of the cover has a curved lip to help prevent drainage directly onto the connectors, while the sides drain to the outside of the boot.

The protective boot is made of a durable silicon based compound. This material has been designed to handle temperature extremes in excess of -50°C and 100°C (-58°F to 212°F) and still remain flexible. Construction sites, mines, quarries and other job sites are constantly changing and can often have adverse weather conditions. The Boot protects the Micromate unit from any accidental dropping, crushing or other impacts. The Micromate Protective Boot and Cover is an inexpensive way to protect your investment in the Micromate monitoring unit.
