Communications and data retrieval
Delta-T offers a range of communication solutions:
RS232 cable - for distances up to 50m a weatherproof RS232 cable can connect the logger to a PC.
GSM modem - DL2e and GP1 software supports GSM modem communications. Range unlimited, subject to network coverage. Enables automatic data collection from remote sites.
PSTN modem - DL2e and GP1 software support landline communications over the national telephone network.
PDA - Pocket DeltaLINK software is available to allow the GP1 and DL6 loggers to be connected to a PDA (iPAQ 2200 Series). With Pocker DeltaLINK, users can collect and graphically view data in the field (and reconfigure the logger, if desired).

Power supply options, including solar panels
All the Delta-T loggers have internal batteries which often provide sufficient power to operate the logger for several months (longer in the case of the GP1). Should additional power be required, several options are available:
Mains power - Some Delta-T loggers can be used with mains power adaptors.
DL2e Logger has a weatherproof socket that can accept 7 – 15V DC.
GP1 Logger can be accept 12V DC power via its external IP68 socket.
DL6 Logger can only be run from its internal batteries.
Rechargeable 12V batteries - Additional batteries with capacities ranging from 1.8 Ah to 115 Ah can be supplied, complete with an appropriate mains charger. Special housings are available for the larger battery sizes.
Solar Recharging systems - Solar charging systems are supplied complete with mounting brackets, a voltage regulator, casing, cabling and waterproof connectors. Rechargeable batteries and battery boxes are ordered separately. Delta-T can assist with calculating the power requirements for any combination of sensors and loggers, including the correct sizing of solar panels for specific geographical locations.
Enclosures, cable routing and power handling
Complex systems can involve a large number of cables and terminal connections. There may also be modems, solar panels, external batteries and relays to wire-in. To assist customers we can supply weatherproof enclosures, complete with wiring kits.
The cost of the enclosure includes the fitting and partial pre-wiring of any loggers, power supplies, relay and modems ordered at the same time. This makes installation in the field faster and simpler.
For battery powered installations we offer the M-ENCL-B Enclosure and Wiring Kit, based on a lockable, IP54 rated, steel enclosure. Fitted inside the enclosure is a fully assembled back-plate mounted wiring system, with DIN rail, trunking, sensor power distribution and fused input power terminals.
For mains powered installations we offer the M-ENCL-M version which is similar to the M-ENCL-B, but also includes a mains transformer and isolator.
Masts
Delta-T masts come complete with everything needed to assemble and install them on-site. Our standard mast is 2m high; taller options can be quoted on request. We can also quote for customised masts with, for example, additional cross arms, non-standard fixings or with telescopic action.
Further details and advice on logger and weather station accessories can be obtained from your Delta-T distributor or direct from Delta-T Devices.
