PM15PS
Sensor for humidity and temperature
with RS232 signal level converter

for digital transfer of the measurement values
Rod design
with exchangeable „Plug and Measure Unit“ PMU
Description
The PM15PS transmitter by Galltec+Mela combines digital
Plug-and-Measure technology with the advantages of a
digital RS232 output, making it suitable for data transfer via
a network or the Internet.
Equipped with the serial Sub-D jack, the PM15PS is suitable for being installed in systems and also for local applications, for example with a laptop.
Like all Plug-and-Measure sensors, the PM15PS is equipped with a digital PMU: The capacitively measured humidity
values and the temperature values measured by using a
PT1000, are calculated in the calibrated Plug-and-Measure
Unit PMU, with the calibration values stored there, and are
passed on as digital measurement values. The PMU measuring heads are exchangeable and can be factory-calibrated
and readjusted using software.

Software „VisualPMU“ (Freeware)
This simple and very clear visualisation software supports
the data output of a sensor via a serial interface on the PC
or Laptop without an additional power supply.
For USB connections, a USB adapter can be supplied.

The relative humidity, the dew point and the temperature (°C
or F) can be displayed and can be depicted as a graph. Apart
from that, the programme has a simple data logger function.
Recorded data can be exported to other programmes.
This freeware version can be obtained from our Homepage
www.galltec-mela.de as a free of charge download..
