The SDM-CD8S controls the pumps in this system. It is an 8-channel solid-state dc controller that has a voltage range of 8 to 26 Vdc. The SDM-CD8S can deliver up to 1.5 A per channel with a maximum of 6 A total for all channels.
The CS106 measures barometric pressure for the range of 500 to 1100 millibars (below sea level as in a mine to 18,000 feet above sea level). A 12 V switching circuit is included in the sensor; a datalogger control port is used to control 12 Vdc power to the sensor, reducing power consumption.
The 6290 provides a Phillips head screwdriver. This screwdriver can drive the #505 screws into the #6044 grommets, which are in turn seated into the square holes in our enclosure backplates.
The 8125 is a small, flat-bladed screwdriver that is extremely useful for opening the guillotine terminals on our dataloggers and measurement control devices.
