Analog Sensor

The analog sensor compatible with DTect-IT is a four channel, USB bus powered sensor with optical isolation and input protection. The sensor has the following specifications:

• Resolution: 16 bit
• Sample Rate: 16 ksps

Each channel is configurable within DTect-IT to various input and output modes. Each channel can be set to the following input modes:

• Voltage Mode- This mode has a range of -10V to +10V with the following options:
• ± 10 V
• ± 5 V
• ± 2.5 V
• 0-10 V
• 0-5 V
• Current Mode- This mode has a range of ± 25 mA.

Analog Sensor Module

Current Mode

Any device that can output a 4 to 20 mA analog current signal can be attached to the analog sensor and utilized by DTect-IT. This type of output is common in pressure and coolant sensors. DTect-IT receives the signal through the analog sensor and transforms the varying current based on the programmed settings of the analog sensor. DTect-IT correlates the 4 to 20 mA signal to a programmed range of data to be utilized by analyses.

For example, if using the analog sensor to read a current signal from a temperature sensor rated for -40°C to 85°C, the range of current that is associated with the range of temperature that needs to be monitored needs to be programmed in the Analog Channels tab. The low range of the current (4 mA) could be associated with -20 °C and the high range (20 mA) could be associated with 40 °C. As the current signal varies, the data output from DTect-IT would range from -20 to 40 °C.
