Manual MWS 55 / MWS 88 / MWS 10 and Sensors 55
3.4.9 Ultraviolet-radiationsensor (UV-Sensor) (Option)
measures ultraviolet radiation (UV-A) in mW/m². The spectral range is 320nm..395nm.
Range: 0 to 50000 mW/m²
Measuring accuracy: +/-10%
3.4.10 Additional Sensor
Any kind of sensors can be integrated as additional sen sors. The information signal must be
applied as volt age in the range between 0 V and + 4.095 V or it has to be adapted to MWS 55 by
a special amplifier. Negative or high er voltages are blocked, but out of security reasons, should
be avoided in any case!
The signals are linearized with up to 8 programmable inpterpolation value pairs by the MWS 55.
We can deliver a temperature sensor for measuring the soil or water temperature and a sensor
for measuring the temperature of the road surface.
The MWS 55 can be equipped with an input for current signals (0..20mA). The signal of the cur-
rent input is applied to pin6 and pin7 of the additional sensors socket. The sensors output has the
sensor identifier ZC in that case sensor ZB can't be used in paralled to the current measurment!
Additional sensors can be voltage supplied by the weather station as long as their current con-
sumption is below 100 mA.
NOTE
If current consumption exceeds this value, we cannot grant that MWS 55 weather station works
properly !!!
If they need higher currents, the sensors must have an external power supply and its ground has
to be connected to the MWS 55-ground (Pin 1 of the 8-pole connector socket).
You can call for adjustment instructions of the additional inputs at any time.
3.4.11 Connecting an Additional Sensor
Additional sensors are connected to MWS 55 at the 8-pole socket.
The socket is allocated as follows:
Pin1 : GND
Pin2 : Input for precipitation sensor (TTL-pulse) - MWS 55, MWS 88, Sensors 55
Pin2 : Input for TTL-pulses - MWS 10
Pin3 : Input for analog additional sensor 4 (0..4.095V)
Pin4 : Input for analog additional sensor 5 (0..4.095V)
Pin5 : Input for analog additional sensor 1 (0..4.095V)
Pin6 : Input for analog additional sensor 2 (0..4.095V)
(option: I- for current input 0..20mA)
Pin7 : Input for analog additional sensor 3 (0..4.095V)
(option: I+ for current input 0..20mA)
Pin8 : Output operating voltage (9..28VDC) maximum 100mA
