Figure 2: Assembly with Sensor-Interface (9.1756.x0.100)

The datalogger DLx-MET is a complete measurement system serving for the acquisition and

storing of at minimum 10 meteorological parameters (e.g. temperature or radiation). Additionally in

the version 9.1756.x0.100 a so-called Sensor-Interface (SIF, see Figure 2) printed circuit board

with several measuring channels is connected to the serial interface COM2. Optional measuring of

other parameters or special sensors with serial output can be done by connecting the so-called

Sensor-Interface or a serial sensor to the serial interface COM2 or COM3 (RS485 2W, 2-Wire, half-

duplex). The serial interfaces COM1 (used for commands and data output) and COM2 are

adjustable from operation mode RS232 to RS485-4W (4-Wire, full-duplex). See below Figure 3 for

a overview of all interfaces.

Figure 3: Interfaces of the datalogger

The instrument is battery-operated (12V), thus allowing it to be set up according to model and

sensor equipment at site without any mains supply for some hours or even days (applies not for

sensors measured by the Sensor-Interface). The exchangeable storage battery is situated in the

data logger case. With an optional 12V solar panel it is possible to load the battery.

Additionally a mains power supply (230VAC) can be used, which also supplies (24VAC) the heating

of sensors and the Sensor-Interface (apply only for 9.1756.x0.100). In this case the battery serves

for bridging in case of power failure. The following figure shows the supply possibilities.

Figure 4: Block diagram supply

In order to protect the accumulator against discharging the measurement of the sensors is

interrupted in case the voltage is below 10,5 V (thus the current consumption is minimized). Then,

6 - 56 021579/06/09

the voltage is measured every 5 minutes; when it is higher than 11,0 V the normal measuring

routine is continued.

An integrated lithium battery buffers the contents of the data memory and the clock operation when

no other power supply is available. This means that the saved values and the time are not lost even

when there is no additional power supply.

The housing can be locked, is impermeable to jet-water (IP65), and is a very stable construction.

For shielding against electromagnetic fields the housing is made of stainless steel. In addition,

operation is guaranteed for temperatures ranging from – 30 °C to 60 °C.

The instrument can be easily operated either by means of three keys, via serial interface COM1 or

via USB. The three keys are referred to in the following as"<∆>", "<∇>"ON, and "<ENTER>" (see

Figure 5). A three-line, alphanumeric liquid crystal display (LCD) serves as indicating instrument.

The scanning of the measuring values is selectable in the range from 1 second to 60 minutes. For

each of the 10 internal sensors the scanning, and further processing can be switched on or off

separately. The optional sensors connected to the Sensor-Interface are processed if the datalogger

receives a telegram over the serial interface COM2 (apply only for 9.1756.x0.100).

The measuring values are stored in a memory (CMOS-RAM) with a storing rate of 1 to 60 minutes

for mean values and 1 minute to 6 hours for extreme values. The memories are organized as so-

called ring memory with a capacity of 1.4MB (mean) and 0.5MB (extreme) . If the capacity of the

ring memory is exhausted, the next step is to overwrite the oldest record. The reading-out of the

data can be carried out via the serial interface COM1, USB or via a Secure Digital Memory Card

(SD Card, see chap.5.2 for working types).

There is a so-called switch output available for the supply of an optional GSM-modem; by means of

this contact output the modem can be supplied at up to 6 selectable times a day.

It is possible to synchronize the internal time automatically by means of a separately connectable

DCF77-receiver module (reception range up to 2000km around Frankfurt(Main)/Germany).

For checking the sensors or the measuring inputs the datalogger can be turned into the

maintenance-mode. While this mode is active the measuring values of all the sensors cannot get

into the memory. I.e. values detected during the maintenance-mode are displayed, however, are

not taken into consideration for the calculation of mean- or extreme values.

2.1 MOUNTING

The datalogger is designed for wall-mounting or installation on a mast.

For proper protection against lightning strikes we strongly recommend to connect a preferably short

cable (≤1m) with a cross section greater than 6mm² between the case (see Figure 1, Grounding

Earth) and the mast (if used) with an earth terminal (e.g. grounding bound or main equipotential

bonding conductor). This connection is also necessary when mains (230VAC) is connected to the

datalogger.

It exists two case variants:

• 9.1756.10.x00x (case version A)

• 9.1756.00.x00x (case version B)

For the mast-installation of case version A seven different pipe clips with a diameter from 46 to

137mm are available. For mast-installation with case version B see chap. 2.1.2

2.1.1 Wall-mounting

For mounting on a wall or likewise use the 4 mounting holes:

• diameter 10mm, see

• (applies for 9.1756.00.x0x)

• diameter 8.4mm, see Figure 7 (applies for 9.1756.10.x0x)
