DART CS107L temperature probes

Soil Temperature measurements, in degrees centigrade, were taken from in-situ temperature probes installed at each of the DART sites, both inside and outside of archaeological features. Measurements were taken every 30 minutes between May 2011 and June 2013. The data were logged locally and collected, downloaded and processed every month. Temperature is one of the variables that determine the propogation of energy during geophysical survey, is an important component of plant germination and crop growth and underlies differential thawing. It is postulated that the multi-temporal temperature measurements when analysed with the geotechnical, weather, BEC and APT data will help determine why geophysical surveys vary over the same position, associated issues about vegetation mark formation and thermal detection criteria.

resource.description Soil Temperature data, recorded every 30 minutes, were collected using thermal probes, over a depth of approximately 1m. The probes were installed between May and August 2011. Readings were taken until the boxes either flooded (Autumn 2012 HHQF, HHCC, DDCF) or were removed from the ground (June 2013). The temperature probes were placed, wherever possible, alongside the TDR probes. The location of each probe can be found on the section drawings in the excavation collection. The large number of probes in the 'heavy' soils required the use of two multiplexors which meant that two data files were created for each site (given the suffix A (where all the probes were installed in the archaeology) and N (where all the probes were installed in the 'natural'). The probes in the well draining soils were given the suffix B to refer to installation in 'Both' archaeology and 'natural'. The exact locations for the probes are as follows: DDCF: DDPF: HHQF: HHCC: The probes measure resistive change and convert this into temperature using the Steinhart and Hart equation The aim is to provide a better understanding of when contrast between archaeological features and the surrounding soil matrix occurs and what causes this contrast in order to optimise geophysical surveys. SPECIFIC INFORMATION ON TEMPERATURE PROBES AND SETTINGS Soil temperature data at different depths was measured using Campbell Scientific 107-L thermal probes with 5m of cable in half bridge circuit. The 107 is a rugged, accurate probe that measures temperature of air, soil, or water from -35 degree to +50 degree C. It easily interfaces with most Campbell Scientific dataloggers and can be used in a variety of applications. The 107 consists of a thermistor encapsulated in an epoxy-filled aluminum housing. The housing protects the thermistor allowing the probe to be buried in soil or submerged in water. The 107 is suitable for shallow burial only. Placement of the cable inside a rugged conduit may be advisable for long cable runs especially in locations subject to digging, mowing, traffic, use of power tools, or lightning strikes.

The CFM100 stores the datalogger's data on a removable CompactFlash (CF) card. The CFM100/CF card combination can be used to expand the datalogger's memory, transport data/programs from the field site(s) to the office, and upload power up functions. The module connects to the 40-pin peripheral port on a CR1000 or CR3000 datalogger. Technical Description: The CFM100 includes a card slot that can fit one Type I or Type II CF card. Only industrial-grade CF cards should be used with our products. Although consumer-grade cards cost less than industrial-grade cards, the consumer-grade cards are more susceptible to failure resulting in both the loss of the card and its stored data. Industrial-grade cards also function over wider temperature ranges and have longer life spans than consumer-grade cards. Data stored on the card can be retrieved either by removing the card and carrying it to a computer or through a communications link with the datalogger. The computer can read the CF card either with the computer's PCMCIA slot and the CF1 adapter or the computer's USB port and the 17752 Reader/Writer. CFM100 Specifications: Typical Access Speed: 200 to 400 kbits s-1. Memory Configuration: User selectable; ring (default) or fill-and-stop. Power Requirements: 12 V supplied through the datalogger's peripheral port. CF Card Requirements: Industrial-grade; storage capacity of 2 GB or less.

Typical current drain: RS-232 Port Active Writing to Card: 30 mA Reading Card: 20 mA RS-232 Port Not Active Writing to Card: 20 mA Reading Card: 15 mA. Low Power Standby: 700 to 800 microA.
