Completely Automated Wireless Monitoring and Archiving

Many CAS DataLoggers customers utilize Accsense A1-09 Wireless Voltage Data Loggers to record and monitor voltage for their critical applications in healthcare, health sciences, and research and manufacturing. These wireless data logger pods are specifically designed to hook up to 6 analog inputs, allowing an increase in the number of sensors per pod and significantly reducing the user’s cost per measurement. This brief technical guide outlines the 3 easy steps needed to connect and properly scale 0-5V signals to these devices. All you’ll require is the Accsense A1-09 pod itself and up to 6 sensors with 0-5V outputs.


  1. First you’ll wire up the data logger. The A1-09 pod can take up to 6 analog inputs and 2 digital (switch) inputs. To wire a current input, either pin 1 or pin 10 can be used as the ground, and pins 4-9 will be the signal return.  As an example, the input for ‘channel 1’ will be on terminal 4, ‘channel 2’ on pin 5, etc.


  1. Once your sensors are wired up, you’ll need to scale them so that they read in the proper engineering units.  In order to do this, you’ll need the ‘Accsense Online Calibration Coefficients Utility’. This utility is pretty straightforward. The default setting when you first open the utility will be set for 4-20ma, so you will need to change it to 0-5V.  Set the ‘Physical Input Range’ boxes as the bottom and top measurements that your transducer is capable of (i.e. 0-5000 PSI).


  1. Once you enter these numbers, press ‘Calculate,’ and now the ‘Coefficient’ boxes will populate.  These values will be entered into the ‘Advanced’ tab in the preferences for the probe.  (The preferences icon will be located on the far right of the webpage).  Make sure to check in the ‘General’ tab that the units are set properly.

Now when you start taking readings, you will see everything scaled properly and with the correct units on both the graph and in the downloaded data.

Accsense data logging systems enable wireless or wired monitoring to record common parameters such as temperature, current, voltage, and many more. The Accsense wireless monitoring system will automatically send data to a secure server where it is stored. With the data coming in, you can setup sophisticated alarms to monitor the data to send out email, pager or phone notifications whenever an alarm goes off. Additionally, operators can use a standard web browser to sign in to retrieve reports and graphs or modify the system configuration from anywhere an internet connection is available.
