Auto-Id Sensors - Texas Instruments CBL 2 Reference Manual

Auto-ID Sensors

The CBL 2 contains provisions for the auto-ID sensor resistor values listed below. If
needed, a conversion equation is loaded automatically for some of the auto-ID values.
IDENT
Valu e 1 Sensor Type
2.2K Thermocouple °C
33K TI Voltage sensor
6.8K Current sensor
3.3K Resistance sensor
22K Extra long temperature sensor for °C
68K CO gas sensor (PPM)

100K Oxygen gas sensor (PCT)
150K C V voltage sensor (V)
220K C V current sensor (A)
10K Stainless steel or TI temperature sensor
15K Stainless steel or TI temperature sensor for °F
4.7K TI Light sensor
1K Ex heart rate sensor (BPM)
47K Voltage sensor

1
IDENT values are resistance values in ohms (tolerance ±5%).
2
Operation 3 is a mathematical conversion of voltage to a current reading (1V=1A).
There is no circuitry inside the CBL 2 unit to convert current to voltage; this must be
done in the external probe.
