MicroLog External Input Sensors
Below are the specifications for the optional external sensors that are
available for the MicroLog external
input channels available on the EC600, EC650, EC700 and EC750 Data Loggers.
DT132 External Temperature Sensor with Probe
This MicroLog sensor takes external
temperature measurements in a wider range than the
internal temperature sensor. With a faster response
time than the internal sensor, it enables measuring
materials that cannot be measured with the internal
sensor. Download the

0-10 Voltage Sensor
A general sensor that will measure
any device or transmitter that produces a linear
analog 0-10V output. The voltage can easily be
converted to the correct measured units with the
help of the MicroLab program. Download the
0-10 Volt Sensor PDF file.
| Range |
0-10V |
| Accuracy |
±3% before calibration |
| Input Impedance |
3M |
| Calibration |
Two point calibration |
| OV Protection |
+30V |
| Resolution |
0.05V |
0 - 20 mAmp External Current Sensor
This MicroLog external sensor can sample
any device or transmitter, producing a linear current
between 0-20 mA. The 0-20 mA can be converted to
the correct measured units by using MicroLab's calibration
option. Download the 0-20
mAmp External Sensor PDF file.
| Range |
0-20mA |
| Resolution |
±0.1mA |
| Accuracy |
±3% before calibration |
| Calibration |
Two point calibration |
| OC Protection |
55mA |
External Contact Adapter
This MicroLog sensor monitors Reed
Relay contacts and switch status (open/closed), to
identify the correlation between phenomena such
as temperature change and door status. Download
