How to use

With 8 digital inputs and 8 digital (logic) inputs, with the DS-108 you can monitor temperatures and the status (on/off, open/closed) of items of equipment or inputs.

Setting up the DS-108 is easy; secure the various temperature probes to the equipment to be monitored, plug each into the datalogger connect the logic inputs to the rear of the datalogger; the digital inputs accepts +2V to +30Vdc as a logic 1, voltages below +2V are considered logic 0. The logger has a +5V (400mmA) output to power external signal conditioning circuitry.

Connect the USB lead to the PC and open the software. The DS-108 is powered from the PC USB port, so a separate power supply is not needed.

In the software set the sampling period. Note, the DS-108 sends all temperatures and digital input statuses to the PC every second, setting the sampling period does not vary this, it does however let you save the data less frequently, for example every 30 seconds, Settable from 1 second to 60 seconds or 1 minute to 60 minutes.

Once set the software will start to display and save the data from the datalogger. You can choose to view a dashboard with alarm levels set and shown or you can view a graph of the temperatures and digital inputs.

Some real-life examples of use of the DS-108:-
Temperature profile of a commercial refrigerator was monitored, the internal temperature was correlated to the external ambient temperature, compressor activity, door open/closed and fan activity.
A renewable energy home heating system was monitored, temperatures of the hot water storage tank, boiler, feed and return pipes were correlated to the heating demand, boiler activity, and various valve positions (open/closed).
A battery charging system was monitored, temperature of battery packs, charger and ambient temperature, also recorded was the charge status (charging or not) as well as current demand, battery delivering power or not.
New underfloor heating system, DS-108 was used to monitor temperatures of, home floor, walls, ambient, whether or not heat demand was on/off as well as valve position (open/closed).
Engine testbed, used to monitor engine, air and coolant temperatures, digital inputs used to log fan on/off and ram air (on/off).

FAQ

Q1. How does a DS-108 record data?

A. The DS-108 sends data to the PC every second, the PC software we provide takes this data and saves it according to your settings. You can also view a graph of the data, a dashboard, or indeed minimise the program to allow background logging. All the data 8 external temperature channels, 1 internal temperature channel and 8 digital voltage input channel statuses are all displayed and saved to disk.

Q2. How long can it record for?

A. It can record continuously. at the end of each day the software automatically starts a new data file for that day and continues to save data until you stop it.

Q3. Can the software be run on Linux or a MAC?

A. No, only PC Windows based at present, however we are developing the software to run on these other ‘platforms’.
